CVE-2011-1426: n/a vulnerability

CVE-2011-1426: The OpenURLInDefaultBrowser method in RealNetworks RealPlayer 11.0 through 11.1 and 14.0.0 through 14.0.2,...

The OpenURLInDefaultBrowser method in RealNetworks RealPlayer 11.0 through 11.1 and 14.0.0 through 14.0.2, and RealPlayer SP 1.0 through 1.1.5, launches a default handler for the filename specified in the first argument, which allows remote attackers to execute arbitrary code via a .rnx filename corresponding to a crafted RNX file.

Security readout for executives and security teams

This is an old RealPlayer remote code execution issue. A vulnerable RealPlayer component can open a crafted RNX-related filename in a way that may run attacker-controlled code. Business risk is mainly legacy desktop exposure where affected RealPlayer versions remain installed. Exposure is likely limited to endpoints that still have the listed legacy RealPlayer versions installed or file associations that route RNX content to RealPlayer components. Prioritize as a legacy endpoint hygiene issue with high impact if present. It is unlikely to matter in modern standard builds, but any retained affected RealPlayer installation should be remediated or removed. Mitigation focus: Inventory endpoints for affected RealPlayer and RealPlayer SP versions.; Apply RealNetworks guidance from the April 12, 2011 player security advisory.; Remove RealPlayer where there is no current business requirement..
