CVE-2008-3806

TITLE

Cisco IOS In UDP Vulnerability in packet processing

DESCRIPTION

Cisco IOS 12.0 through 12.4 on Cisco 10000, uBR10012 and uBR7200 series devices handles external UDP packets that are sent to 127.0.0.0/8 addresses intended for IPC communication within the device, which allows remote attackers to cause a denial of service (device or linecard reload) via crafted UDP packets, a different vulnerability than CVE-2008-3805. Provided by Cisco Systems Cisco IOS The denial of service (DoS) There are vulnerabilities. This vulnerability is CVE-2008-3805 This is a different vulnerability.See the "Summary" for the impact of this vulnerability. Ios is prone to a denial-of-service vulnerability. ---------------------------------------------------------------------- Do you need accurate and reliable IDS / IPS / AV detection rules?

Successful exploitation requires that the device is configured with Network Address Translation (NAT) SCCP Fragmentation Support. 4) A memory leak in the processing of Session Initiation Protocol (SIP) messages can be exploited to cause a DoS for all voice services. 5) Multiple unspecified errors exist in the processing of SIP messages, which can be exploited to cause a reload of an affected device. 6) An unspecified error in the IOS Intrusion Prevention System (IPS) feature when processing certain IPS signatures that use the SERVICE.DNS engine can be exploited to cause a DoS via specially crafted network traffic. 7) A security issue exists in the processing of extended communities with Multi Protocol Label Switching (MPLS) Virtual Private Networks (VPN), which can lead to traffic leaking from one MPLS VPN to another. This security issue does not affect Cisco IOS releases based on 12.1. NOTE: This security issue was introduced with CSCee83237. Cisco IOS images that do not include CSCee83237 are reportedly not affected. 8) An unspecified error within the Multi Protocol Label Switching (MPLS) Forwarding Infrastructure (MFI) can be exploited to cause a DoS via specially crafted network packets. Successful exploitation requires access to the MPLS network. 9) An unspecified error within the Application Inspection Control (AIC) can be exploited to cause a reload of an affected device via specially crafted HTTP packets. 10) An unspecified error in the processing of Layer 2 Tunneling Protocol (L2TP) packets can be exploited to cause an affected device to reload via a specially crafted L2TP packets. Successful exploitation requires that the L2TP mgmt daemon process is running. This process may be enabled e.g. via Layer 2 virtual private networks (L2VPN), Layer 2 Tunnel Protocol Version 3 (L2TPv3), Stack Group Bidding Protocol (SGBP), or Cisco Virtual Private Dial-Up Networks (VPDN). 11) An unspecified error exists in the processing of IPC messages. This vulnerability is reported in Cisco 10000, uBR10012, and uBR7200 series devices. 12) A security issue is caused due to the device automatically enabling SNMP with a default community string, which can be exploited to gain control an affected system. Successful exploitation requires that a device is configured for linecard redundancy. SOLUTION: Update to the fixed version (please see the vendor's advisories for details). PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
