HylaFAX hfaxd with PAM Password Policy Bypass

high Nessus Plugin ID 20387

Language:

Synopsis

The remote fax server fails to properly validate passwords.

Description

The remote host is running HylaFAX, a fax / pager server application for Linux / unix.

The version of HylaFAX installed on the remote host does not check passwords when authenticating users via hfaxd, its fax server. An attacker can exploit this issue to bypass authentication using a valid username and gain access to the system.

Solution

Rebuild HylaFAX with PAM support or upgrade to HylaFAX version 4.2.4 or later.
