medium Nessus Plugin ID 209806

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-20-126 advisory.

 - A stack-based buffer overflow vulnerability in FortiWeb 6.3.0 through 6.3.7 and version before 6.2.4 may allow a remote, unauthenticated attacker to crash the httpd daemon thread by sending a request with a crafted cookie header. (CVE-2020-29019)

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 FortiWeb version 6.2.4/6.3.8 or later.
