Description:
Tan Chew Keong has reported a vulnerability in CGI::Session, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to an input validation error in the "File" driver when handling the "CGISESSID" cookie value. This can be exploited to cause the "File" driver to read session data from arbitrary files outside of the session data directory via directory traversal sequences.
Successful exploitation requires that the target application using CGI::Session is on Windows and that an attacker is able to place a file containing valid session data on a known location on the target system.
The vulnerability is reported in version 3.94, 3.95, and 4.33. Other versions may also be affected.
