The helper application in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.5.3041, and 3.0.x before 3.0.629, on Linux and Mac OS X downloads a client executable file (vpndownloader.exe) without verifying its authenticity, which allows remote attackers to execute arbitrary code via the url property to a Java applet, aka Bug ID CSCsy05934.

Security readout for executives and security teams

Older Cisco AnyConnect clients on Linux and Mac OS X could be tricked into running attacker-supplied code because a helper downloaded a client executable without verifying authenticity. This is most urgent where legacy AnyConnect clients remain deployed. Exposure is likely limited to organizations still running affected Cisco AnyConnect Secure Mobility Client versions on Linux or Mac OS X, especially legacy VPN launch or upgrade workflows involving the Java applet helper. Treat as a legacy-client cleanup priority. The business risk is code execution on endpoints used for VPN access, but urgency depends on whether affected Mac or Linux clients still exist. Mitigation focus: Upgrade affected AnyConnect clients to 2.5.3041, 3.0.629, or later supported releases.; Use Cisco’s advisory for exact fixed builds and deployment guidance.; Prioritize Linux and Mac OS X endpoints with legacy AnyConnect installations..
