CVE-2007-1826: Unspecified vulnerability in the IPSec Manager Service for Cisco Unified CallManager (CUCM) 5.0 before 5.0(...

Unspecified vulnerability in the IPSec Manager Service for Cisco Unified CallManager (CUCM) 5.0 before 5.0(4a)SU1 and Cisco Unified Presence Server (CUPS) 1.0 before 1.0(3) allows remote attackers to cause a denial of service (loss of cluster services) via a "specific UDP packet" to UDP port 8500, aka bug ID CSCsg60949.

Security readout for executives and security teams

This is an old Cisco voice and presence service flaw that could let a remote attacker disrupt cluster services by sending a crafted UDP packet to port 8500. The business risk is service interruption, not data theft, based on the supplied sources. Exposure is most likely in legacy Cisco Unified CallManager 5.0 or Unified Presence Server 1.0 environments where UDP port 8500 is reachable from untrusted or poorly segmented networks. Treat this as a legacy service availability risk. Prioritize if affected voice or presence systems still support business operations, especially where network segmentation is weak. Mitigation focus: Upgrade CUCM 5.0 to 5.0(4a)SU1 or later vendor-fixed guidance.; Upgrade CUPS 1.0 to 1.0(3) or later vendor-fixed guidance.; Restrict UDP port 8500 to trusted cluster-management paths only..
