VAR-201302-0391

Vulnerability from variot - Updated: 2025-04-11 20:08

Cisco Unified Communications Manager (CUCM) 8.6 before 8.6(2a)su2, 8.6 BE3k before 8.6(4) BE3k, and 9.x before 9.0(1) allows remote attackers to cause a denial of service (CPU consumption and GUI and voice outages) via malformed packets to unused UDP ports, aka Bug ID CSCtx43337. Successful exploits could allow a remote attacker to trigger a memory leak or cause denial of service condition resulting in the interruption of voice services. This issue is documented by the Cisco bug ID CSCtx43337. This component provides a scalable, distributed and highly available enterprise IP telephony call processing solution
