CVE-2006-2322: The transparent proxy feature of the Cisco Application Velocity System (AVS) 3110 5.0 and 4.0 and earlier,...

Security readout for executives and security teams

Cisco AVS appliances could, by default, let outsiders use the device as a TCP relay. In business terms, an exposed system could be abused to hide traffic, reach other services through the appliance, or create trust-boundary confusion. The source bundle does not provide CVSS, active exploitation evidence, or a confirmed patch detail. Exposure is most likely where legacy Cisco AVS 3110 or 3120 appliances still exist and have transparent proxy reachable from untrusted networks. The bundle’s affected-product metadata is sparse, so inventory confirmation is essential. Prioritize discovery first. This is a legacy Cisco appliance issue with potentially serious relay abuse, but the provided evidence lacks CVSS and exploitation confirmation. Escalate if any affected AVS device is internet-facing or bridges sensitive internal networks. Mitigation focus: Inventory Cisco AVS 3110 and 3120 appliances and versions.; Check Cisco advisory for corrected software or configuration guidance.; Restrict transparent proxy access from untrusted networks..
