CVE-2012-1335: Buffer overflow in the Cisco WebEx Recording Format (WRF) player T27 L through SP11 EP26, T27 LB through SP...

Security readout for executives and security teams

A legacy Cisco WebEx recording player could be made to run attacker-controlled code if it opens a specially crafted WRF recording file. This is primarily an endpoint and file-handling risk, not evidence of an exposed internet service flaw. Exposure is likely limited to systems with the affected Cisco WebEx WRF player installed, especially where users handle archived or externally supplied WebEx recording files. The provided sources do not identify affected operating systems or deployment prevalence. Treat as a high-priority legacy software cleanup item if WebEx WRF playback is still used. The business risk is code execution from a malicious recording file, but urgency is reduced where the player is absent or untrusted WRF files are blocked. Mitigation focus: Inventory endpoints for the listed Cisco WebEx WRF player versions.; Review Cisco advisory cisco-sa-20120404-webex for vendor-approved updates or replacements.; Upgrade or remove vulnerable WebEx Player installations according to Cisco guidance..
