Secunia Research has discovered a vulnerability in WinGate, which can be exploited by malicious users to disclose potentially sensitive information and bypass certain security restrictions.
The vulnerability is caused due to an input validation error in the IMAP service during handling of the "CREATE", "SELECT", "DELETE", "RENAME", "COPY", "APPEND", and "LIST" commands. This can be exploited by an authenticated user to read other users' emails, create/rename arbitrary directories on the system, and delete certain directories via directory traversal attacks.
The vulnerability has been confirmed in versions 22.214.171.1244 and 126.96.36.1996. Other versions may also be affected.
Solution: Update to version 6.1.4 Build 1099 or later.
