Fortinet FortiProxy Out-of-bound Write in sslvpnd (FG-IR-24-255)

medium Nessus Plugin ID 211865

Synopsis

The version of FortiProxy installed on the remote host is missing one or more security-related updates.

Description

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.

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

Solution

Please upgrade to FortiProxy version 7.4.6 or later.
