WinRAR before 5.30 β5 lets local users elevate rights

CVE-2015-5663 · published 10 years ago
Summary

The version of WinRAR released before the 5.30 beta 5 update can be tricked by a specially named file to run code with higher privileges than a normal user. This means someone with access to the computer could potentially gain more control over the system. Updating WinRAR to version 5.30 beta 5 or later resolves the issue.
