CVE-2013-3461: Cisco Unified Communications Manager (Unified CM) 8.5(x) and 8.6(x) before 8.6(2a)su3 and 9.x before 9.1(1)...

Cisco Unified Communications Manager (Unified CM) 8.5(x) and 8.6(x) before 8.6(2a)su3 and 9.x before 9.1(1) does not properly restrict the rate of SIP packets, which allows remote attackers to cause a denial of service (memory and CPU consumption, and service disruption) via a flood of UDP packets to port 5060, aka Bug ID CSCub35869.

Security readout for executives and security teams

This flaw can let a remote attacker disrupt Cisco Unified Communications Manager by overwhelming its SIP handling. The business impact is voice service degradation or outage, not data theft based on the supplied sources. Exposure is most relevant where Cisco Unified CM SIP services are reachable from untrusted or broadly reachable networks. Internet-facing or poorly segmented voice infrastructure would raise urgency. Prioritize remediation if Unified CM supports critical voice operations or is reachable beyond trusted voice networks. Treat as business continuity risk rather than confirmed breach risk. Mitigation focus: Inventory Cisco Unified CM versions and identify 8.5(x), vulnerable 8.6(x), and vulnerable 9.x systems.; Upgrade to Cisco fixed releases: 8.6(2a)su3, 9.1(1), or later vendor-supported guidance.; Restrict SIP/UDP 5060 reachability to trusted voice infrastructure where operationally possible..
