CVE-2011-1426
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe OpenURLInDefaultBrowser method in RealNetworks RealPlayer versions 11.0-11.1, 14.0.0-14.0.2, and SP 1.0-1.1.5 improperly handles the filename argument, allowing remote attackers to execute arbitrary code by supplying a crafted RNX file that gets processed by the system's default handler.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine if RealPlayer is installedCheck your system for RealPlayer by looking in Add/Remove Programs (Windows) or Applications folder (Mac), or search for RealPlayer executables on the systemAffected if RealPlayer is present on the system
-
Identify the installed RealPlayer versionOpen RealPlayer and navigate to Help > About, or check the program's version property, or examine the version information of the RealPlayer executable in Program FilesAffected if The installed version matches 11.0, 11.1, 14.0.0, 14.0.1, 14.0.2, or any SP version from 1.0.0 through 1.1.5
-
Check RNX file associationVerify if .rnx files are associated with RealPlayer as the default handler by examining file type associations in your operating system settingsAffected if RealPlayer is set as the default handler for RNX files and those files can be opened automatically
You are affected if RealPlayer versions 11.0-11.1, 14.0.0-14.0.2, or SP 1.0-1.1.5 are installed and RNX files can be processed by the application.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patches from RealNetworks to update to a non-vulnerable RealPlayer version, or uninstall RealPlayer if unnecessary, as the vulnerability allows complete system compromise via the OpenURLInDefaultBrowser method.
