VAR-200710-0496
Vulnerability from variot - Updated: 2023-12-18 12:39Cisco Unified Communications Manager (CUCM, formerly CallManager) 5.1 before 5.1(2), and Unified CallManager 5.0, allow remote attackers to cause a denial of service (kernel panic) via a flood of SIP INVITE messages to UDP port 5060, which triggers resource exhaustion, aka CSCsi75822. Cisco Unified Communications Manager is prone to a denial-of-service vulnerability and a buffer-overflow vulnerability. Successfully exploiting these issues allows remote attackers to crash affected devices by triggering kernel panics or to execute arbitrary machine code. These issues facilitate the complete remote compromise of affected devices. Versions of Cisco Unified Communications Manager in the 5 and 6 series prior to 6.0(1) are affected by these issues. A denial of service vulnerability exists in the CUCM Session Initiation Protocol (SIP) stack
