Debian DSA-2259-1 : fex - authentication bypass

medium Nessus Plugin ID 55066

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that F*EX, a web service for transferring very large files, is not properly validating authentication IDs. While the service properly validates existing authentication IDs, an attacker who is not specifying any authentication ID at all can bypass the authentication procedure.

The oldstable distribution (lenny) does not include fex.

Solution

Upgrade the fex packages.

For the stable distribution (squeeze), this problem has been fixed in version 20100208+debian1-1+squeeze1.
