Fortinet FortiWeb RADIUS Protocol CVE-2024-3596 (FG-IR-24-255)

critical Nessus Plugin ID 232300

Language:

Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of FortiWeb installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-24-255 advisory.

- RADIUS Protocol under RFC 2865 is susceptible to forgery attacks by a local attacker who can modify any valid Response (Access-Accept, Access-Reject, or Access-Challenge) to any other response using a chosen- prefix collision attack against MD5 Response Authenticator signature. (CVE-2024-3596)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

For 7.0.x / 7.2.x, see vendor advisory. For 7.4.x, upgrade to FortiWeb version 7.4.5 or later. For 7.6.x, upgrade to FortiWeb version 7.6.1 or later.
