CVE-2008-3807

TITLE

Cisco uBR10012 Runs on series devices Cisco IOS of SNMP Service community name vulnerability

DESCRIPTION

Cisco IOS 12.2 and 12.3 on Cisco uBR10012 series devices, when linecard redundancy is configured, enables a read/write SNMP service with "private" as the community, which allows remote attackers to obtain administrative access by guessing this community and sending SNMP requests. Cisco uBR10012 routers are high-performance network devices. The routers are prone to a weak default configuration issue. A remote attacker may exploit this issue to gain complete access to the vulnerable device. Cisco uBR10012 routers are vulnerable. This issue is being tracked by Cisco bug ID CSCek57932. ---------------------------------------------------------------------- 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 can be exploited to reload an affected device via a specially crafted UDP packet sent to port 1975. 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. This vulnerability affects Cisco uBR10012 series devices running IOS. SOLUTION: Update to the fixed version (please see the vendor's advisories for details). PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
