Name of the Vulnerable Software and Affected Versions: Sympa versions prior to 6.2.32

Description: The issue is related to a directory traversal vulnerability in the wwsympa.fcgi template editing function of the Sympa mailing list manager. This vulnerability can be exploited via specially crafted HTTP GET/POST requests, potentially allowing a remote attacker to elevate privileges and create or modify files on the server filesystem.
