The Disaster Recovery Framework (DRF) master server in Cisco Unified Communications products, including Unified Communications Manager (CUCM) 5.x and 6.x, Unified Presence 1.x and 6.x, Emergency Responder 2.x, and Mobility Manager 2.x, does not require authentication for requests received from the network, which allows remote attackers to execute arbitrary code via unspecified vectors.
SQL injection vulnerability in Cisco Unified CallManager/Communications Manager (CUCM) 5.0/5.1 before 5.1(3a) and 6.0/6.1 before 6.1(1a) allows remote authenticated users to execute arbitrary SQL commands via the key parameter to the (1) admin and (2) user interface pages.
Unspecified vulnerability in Cisco Unified Communications Manager (CUCM) 5.0, 5.1, and 6.0, and IOS 12.0 through 12.4, allows remote attackers to execute arbitrary code via a malformed SIP packet, aka CSCsi80102.
