Fortinet FortiOS Buffer Overflow (FG-IR-21-206)

medium Nessus Plugin ID 163262

Language:

Synopsis

The remote host is affected by a buffer overflow vulnerability.

Description

The remote host is running a version of FortiOS that is 6.0.x through 6.0.14, 6.2.x through 6.2.10, 6.4.x through 6.4.8, or 7.0.x through 7.0.2. It is, therefore, affected by a stack-based buffer overflow vulnerability. An authenticated, remote attacker can exploit this issue, via specially crafted command line arguments, to execute unauthorized code or commands.

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

Solution

Update FortiOS to version 6.2.11, 6.4.9, 7.0.4, or later.
