Name of the Vulnerable Software and Affected Versions FortiOS versions 7.2.0 and below FortiOS versions 7.0.6 and below FortiOS versions 6.4.9 and below

Description The issue is related to errors in managing the RSA SSH cryptographic key, which may allow a remote attacker to perform a man-in-the-middle (MITM) attack. This could potentially be exploited by an unauthenticated attacker.

Recommendations For FortiOS versions 7.2.0 and below, update to a version above 7.2.0 to resolve the issue. For FortiOS versions 7.0.6 and below, update to a version above 7.0.6 to resolve the issue. For FortiOS versions 6.4.9 and below, update to a version above 6.4.9 to resolve the issue. As a temporary workaround, consider restricting access to the RSA SSH host key to minimize the risk of exploitation.
