Description

Endian Firewall version 3.3.25 and prior allow authenticated users to delete arbitrary files via directory traversal in the remove ARCHIVE parameter to /cgi-bin/backup.cgi. The remove ARCHIVE parameter value is used to construct a file path without sanitization of directory traversal sequences, which is then passed to an unlink() call.
