VARIoT IoT vulnerabilities database

Multiple TCP/IP and ICMP implementations, when using Path MTU (PMTU) discovery (PMTUD), allow remote attackers to cause a denial of service (network throughput reduction for TCP connections) via forged ICMP ("Fragmentation Needed and Don't Fragment was Set") packets with a low next-hop MTU value, aka the "Path MTU discovery attack." NOTE: CVE-2004-0790, CVE-2004-0791, and CVE-2004-1060 have been SPLIT based on different attacks; CVE-2005-0065, CVE-2005-0066, CVE-2005-0067, and CVE-2005-0068 are related identifiers that are SPLIT based on the underlying vulnerability. While CVE normally SPLITs based on vulnerability, the attack-based identifiers exist due to the variety and number of affected implementations and solutions that address the attacks instead of the underlying vulnerabilities. A vulnerability exists in the reliance of the Border Gateway Protocol (BGP) on the Transmission Control Protocol (TCP) to maintain persistent sessions. Sustained exploitation of this vulnerability could lead to a denial-of-service condition affecting a large segment of the Internet community. Normal operations would most likely resume shortly after the attack stopped. many OS Implemented in Path MTU Discovery (PMTUD) Then IP This problem was exploited because the anti-splitting flag in the header was set ICMP Receiving messages contains a vulnerability that significantly degrades the network performance of the system.PMTUD Network performance decreases in systems that enable TCP The communication speed of the connection may decrease. Multiple vendor implementations of TCP/IP Internet Control Message Protocol (ICMP) are reported prone to several denial-of-service attacks. ICMP is employed by network nodes to determine certain automatic actions to take based on network failures reported by an ICMP message. Reportedly, the RFC doesn't recommend security checks for ICMP error messages. As long as an ICMP message contains a valid source and destination IP address and port pair, it will be accepted for an associated connection. The following individual attacks are reported: - A blind connection-reset attack. This attack takes advantage of the specification that describes that on receiving a 'hard' ICMP error, the corresponding connection should be aborted. The Mitre ID CAN-2004-0790 is assigned to this issue. A remote attacker may exploit this issue to terminate target TCP connections and deny service for legitimate users. - An ICMP Source Quench attack. This attack takes advantage of the specification that a host must react to receive ICMP Source Quench messages by slowing transmission on the associated connection. The Mitre ID CAN-2004-0791 is assigned to this issue. A remote attacker may exploit this issue to degrade the performance of TCP connections and partially deny service for legitimate users. - An attack against ICMP PMTUD is reported to affect multiple vendors when they are configured to employ PMTUD. By sending a suitable forged ICMP message to a target host, an attacker may reduce the MTU for a given connection. The Mitre ID CAN-2004-1060 is assigned to this issue. A remote attacker may exploit this issue to degrade the performance of TCP connections and partially deny service for legitimate users. **Update: Microsoft platforms are also reported prone to these issues. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HP SECURITY BULLETIN HPSBUX01164 REVISION: 4 SSRT4884 rev.4 - HP-UX TCP/IP Remote Denial of Service (DoS) NOTICE: There are no restrictions for distribution of this Security Bulletin provided that it remains complete and intact.

The latest Transport Functionality is available to B.11.23 customers in the HP-UX 11i v2 September 2004 release. Customers using TOUR on B.11.23 can apply the workaround (set ip_pmtu_strategy= 0 and filter ICMP) or upgrade to the HP-UX 11i v2 September 2004 release. After upgrading the action for B.11.23 Networking.NET2-KRN listed above should be implemented. <http://www.uniras.gov.uk/niscc/docs/al-20050412-00308.html? lang=en> There are three issues reported in NISCC VU#532967: CVE number: CAN-2004-0790 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0790> CVE number: CAN-2004-0791 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0791> CVE number: CAN-2004-1060 <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1060> Workarounds are available for all three of these issues. Until binary files are available for B.11.04 the workarounds should be used. ->Binary files are available for CAN-2004-0790 and CAN-2004-0791 for HP-UX B.11.00 and B.11.22. Since PHNE_33159 is now available for B.11.11 the preliminary binary files for B.11.11 have been removed from the ftp site. ->Since PHNE_32606 is now available for B.11.23 the preliminary binary files for B.11.23 have been removed from the ftp site. Note: If the TOUR (Transport Optional Upgrade Release) product is installed the binary files cannot be used. Until the TOUR product is revised there are several options: B.11.11 1. Use the workarounds. or 2. Remove TOUR and install the binary files. B.11.23 1. Use the workarounds. or 2. Upgrade to the HP-UX 11i v2 September 2004 release and install the binary files. TOUR(Transport Optional Upgrade Release) is available from <http://www.hp.com/go/softwaredepot>. Workaround for CAN-2004-1060 may not be necessary. =================================== Although changes in the binary files and patches for CAN-2004-0790 and CAN-2004-0791 do not prevent the exploit of CAN-2004-1060, they do make it less likely to succeed. The sequence number check suggested in section 5.1 of <http://www.ietf.org/internet-drafts/ draft-gont-tcpm-icmp-attacks-03.txt> has been implemented. Customers should consider whether this check reduces the risk of the exploit to the point that setting ip_pmtu_strategy=0 is not required. If the workaround for CAN-2004-1060 is to be used, please note the following: ================================================= HPSBUX01137 recommends setting ip_pmtu_strategy = 0 or 3 as a workaround for the problem of CAN-2005-1192. CAN-2004-1060 has a different root cause and cannot be worked around with p_pmtu_strategy=3. To work around both CAN-2005-1192 and CAN-2004-1060 ip_pmtu_strategy=0 must be used. Please refer to the Manual Actions section below for a summary of the required actions. Workarounds: CAN-2004-0790 and CAN-2004-0791 Filter out the following ICMP messages: Type 3, Code 2 (Destination Unreachable, Protocol Unreachable) Type 3, Code 3 (Destination Unreachable, Port Unreachable) Type 4, Code 0 (Source Quench) CAN-2004-1060 Set ip_pmtu_strategy=0. Note: Filtering "Protocol Unreachable" and "Port Unreachable" should not be done without careful testing. Filtering these out may interfere with the correct functioning of network components. Filtering "Source Quench" should present little risk. Setting ip_pmtu_strategy=0 ================== Edit /etc/rc.config.d/nddconf to add the following: TRANSPORT_NAME[n]=ip NDD_NAME[n]=ip_pmtu_strategy NDD_VALUE[n]=0 where 'n' is the next available index value as described in the nddconf comments. This value will take effect when the system is rebooted. Until the system can be rebooted use the following command to read the /etc/rc.config.d/nddconf file and set the tunable parameters: /usr/bin/ndd -c The ip_pmtu_strategy parameter can be displayed by the following command: /usr/bin/ndd -get /dev/ip ip_pmtu_strategy Note: Since open connections will remain potentially vulnerable until they are closed and certain internal data structures are released it is recommended that the system be rebooted. Note: There is a defect that will cause "ndd -c" to fail if there are more than 10 directives in /etc/rc.config.d/nddconf. That defect is fixed in the following patches: B.11.11 - PHNE_25644 or subsequent B.11.04 - PHNE_26076 or subsequent B.11.00 - PHNE_26125 or subsequent Preliminary binary files ============== ->Preliminary binary files are available for B.11.00 and B.11.22. Patches are available for B.11.11 and B.11.23. The patches and the preliminary binary files address CAN-2004-0790 and CAN-2004-0791 only. Although changes in the patches and binary files for CAN-2004-0790 and CAN-2004-0791 do not prevent the exploit of CAN-2004-1060, they do make it less likely to succeed.

HP Tru64 UNIX 5.1B-3 HP Tru64 UNIX 5.1B-2/PK4 HP Tru64 UNIX 5.1A PK HP Tru64 UNIX 4.0G PK4 HP Tru64 UNIX 4.0F PK8 BACKGROUND: Special Instructions for the Customer The Internet Control Message Protocol (ICMP) (RFC 792) is used in the Internet Architecture to perform fault-isolation and recovery (RFC816), which is the group of actions that hosts and routers take to determine if a network failure has occurred. The industry standard TCP specification (RFC 793) has a vulnerability whereby ICMP packets can be used to perform a variety of attacks such as blind connection reset attacks and blind throughput-reduction attacks. Path MTU Discovery (RFC 1191) describes a technique for dynamically discovering the MTU (maximum transmission unit) of an arbitrary internet path. This protocol uses ICMP packets from the router to discover the MTU for a TCP connection path. HP has addressed these potential vulnerabilities by providing a new kernel tunable in Tru64 UNIX V5.1B and 5.1A, icmp_tcpseqcheck. In Tru64 4.0F and 4.0G, HP has introduced two new kernel tunables, icmp_tcpseqcheck and icmp_rejectcodemask. icmp_tcpseqcheck The icmp_tcpseqcheck variable mitigates ICMP attacks against TCP by checking that the TCP sequence number contained in the payload of the ICMP error message is within the range of the data already sent but not yet acknowledged. This behavior protects TCP against spoofed ICMP packets. Set the tunable as follows: icmp_tcpseqcheck=1 (default) Provides a level of protection that reduces the possibility of considering a spoofed ICMP packet as valid to one in two raised to the thirty-second power. icmp_tcpseqcheck=0 Retains existing behavior, i.e., accepts all ICMP packets icmp_rejectcodemask In the Requirements for IP Version 4 Routers (RFC 1812), research suggests that the use of ICMP Source Quench packets is an ineffective (and unfair) antidote for congestion. Thus, HP recommends completely ignoring ICMP Source Quench packets using the icmp_rejectcodemask tunable. The icmp_rejectcodemask is a bitmask that designates the ICMP codes that the system should reject. For example, to reject ICMP Source Quench packets, set the mask bit position for the ICMP_SOURCEQUENCH code 4, which is two to the 4th power = 16 (0x10 hex). The icmp_rejectcodemask tunable can be used to reject any ICMP packet type, or multiple masks can be combined to reject more than one type. Note: the ICMP type codes are defined in "/usr/include/netinet/ip_icmp.h". Set the tunable as follows: icmp_rejectcodemask = 0x10 Rejects ICMP Source Quench packets icmp_rejectcodemask = 0 (default) Retains existing behavior, i.e., accepts all ICMP packets Adjusting the variables The ICMP sequence check variable (icmp_tcpseqcheck) can be adjusted using the sysconfig and sysconfigdb commands: # sysconfig -q inet icmp_tcpseqcheck inet: icmp_tcpseqcheck = 1 # sysconfig -r inet icmp_tcpseqcheck=0 icmp_tcpseqcheck: reconfigured # sysconfig -q inet icmp_tcpseqcheck inet: icmp_tcpseqcheck = 0 # sysconfig -q inet icmp_tcpseqcheck > /tmp/icmp_tcpseqcheck_merge # sysconfigdb -m -f /tmp/icmp_tcpseqcheck_merge inet # sysconfigdb -l inet inet: icmp_tcpseqcheck = 1 Similarly, the icmp_rejectcodemask variable can be adjusted using the sysconfig and sysconfigdb commands: # sysconfig -q inet icmp_rejectcodemask inet: icmp_rejectcodemask = 0 # sysconfig -r inet icmp_rejectcodemask=0x10 icmp_rejectcodemask: reconfigured # sysconfig -q inet icmp_rejectcodemask inet: icmp_rejectcodemask = 16 # sysconfig -q inet icmp_rejectcodemask > /tmp/icmp_rejectcodemask_merge # sysconfigdb -m -f /tmp/icmp_rejectcodemask_merge inet # sysconfigdb -l inet inet: icmp_rejectcodemask = 16 RESOLUTION: Until the corrections are available in a mainstream release patch kit, HP is releasing the following Early Release Patch (ERP) kits publicly for use by any customer. The ERP kits use dupatch to install and will not install over any installed Customer Specific Patches (CSPs) that have file intersections with the ERPs.

X-Micro WLAN 11b Broadband Router 1.2.2, 1.2.2.3, 1.2.2.4, and 1.6.0.0 has a hardcoded "super" username and password, which could allow remote attackers to gain access. It has been reported that the firmware shipped with the X-Micro 11b Broadband Router has built-in an administrative account that cannot be disabled. According to the author of the report, the built-in administration webserver listens on both internal and external interfaces. Attackers may authenticate with the "super" account from outside of the LAN and gain control of the device through this web interface. Once authenticated, it is possible for attackers to install new firmware on the device. The account, username and password "1502", appears to be a backdoor and may provide remote attackers possessing knowledge of the account with complete control over the device. X-Micro WLAN 11b is a wireless broadband router. There is a \"super\" account in the firmware, and its password is also \"super\".

FloosieTek FTGatePro Mail Server is a versatile mail server that includes anti-virus integration, anti-spam, NAT SAM integration and more. The FTGate WEB mail server lacks sufficient filtering for user submission parameters, and remote attackers can exploit this vulnerability to obtain user sensitive information. The problem is that 'individual.fts' lacks filtering for the \"Display name\" field. The attacker builds a malicious WEB page to entice the user to access the information such as the sensitive COOKIE of the target user. It has been reported that FTGate is prone to multiple remote input validation vulnerabilities; a cross-site scripting issue and an HTML injection vulnerability. These issues are due to a failure of the application to properly sanitize user supplied input before using it in dynamic web content. The cross-site scripting issue could permit a remote attacker to create a malicious link to the vulnerable application that includes hostile HTML and script code. If this link were followed, the hostile code may be rendered in the web browser of the victim user.
