CVE-2015-4283: Cisco Videoscape Policy Resource Manager (PRM) 3.5.4 allows remote attackers to cause a denial of service (...

Security readout for executives and security teams

This flaw can let a remote attacker overwhelm Cisco Videoscape Policy Resource Manager 3.5.4, consuming CPU and memory and disrupting TCP service. The business impact is service availability, not confirmed data theft or code execution based on this bundle. Exposure appears limited to Cisco Videoscape Policy Resource Manager 3.5.4 deployments, especially TCP services reachable from untrusted networks. The bundle does not identify other affected versions, CPEs, or default exposure conditions. Prioritize if Videoscape PRM supports customer-facing or revenue-critical video services. With no evidence of active exploitation or data compromise in the bundle, treat this as an availability risk requiring inventory and vendor-guidance follow-up. Mitigation focus: Review Cisco advisory alertId 40050 for official fixes or workarounds.; Identify any Cisco Videoscape PRM 3.5.4 systems in the environment.; Reduce untrusted network reachability to PRM TCP services where operationally possible..
