CVE-2008-3802

TITLE

Cisco IOS of SIP In implementation SIP Service disruption related to message processing (DoS) Vulnerabilities

DESCRIPTION

Unspecified vulnerability in the Session Initiation Protocol (SIP) implementation in Cisco IOS 12.2 through 12.4, when VoIP is configured, allows remote attackers to cause a denial of service (device reload) via unspecified valid SIP messages, aka Cisco bug ID CSCsk42759, a different vulnerability than CVE-2008-3800 and CVE-2008-3801. The problem is Bug ID : CSCsk42759 It is a problem. this is CVE-2008-3800 and CVE-2008-3801 Is a different vulnerability.Service operation disrupted by a third party (DoS) There is a possibility of being put into a state. Devices running Cisco IOS with SIP enabled are prone to multiple denial-of-service vulnerabilities. These issues are tracked by the following Cisco bug IDs and CVEs: CSCse56800 (CVE-2008-3799) CSCsg91306 (CVE-2008-3800) CSCsl62609 (CVE-2008-3801) CSCsk42759 (CVE-2008-3802) An attacker can exploit these issues to deny service to legitimate users. Cisco IOS is the Internet operating system used on Cisco networking equipment. A remote attacker causes a denial of service by unidentifying a valid SIP message. ---------------------------------------------------------------------- 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. 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. 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.
