FortiClient before 4.3.5.472 on Windows, before 4.0.3.134 on Mac OS X, and before 4.0 on Android; FortiClient Lite before 4.3.4.461 on Windows; FortiClient Lite 2.0 through 2.0.0223 on Android; and FortiClient SSL VPN before 4.0.2258 on Linux proceed with an SSL session after determining that the server's X.509 certificate is invalid, which allows man-in-the-middle attackers to obtain sensitive information by leveraging a password transmission that occurs before the user warning about the certificate problem.

Security readout for executives and security teams

Older FortiClient VPN products could continue an SSL connection even after detecting an invalid server certificate. Because a password was transmitted before the warning, a person controlling the network path could intercept credentials during a man-in-the-middle scenario. Exposure is mainly legacy endpoint VPN clients running versions below the fixed thresholds listed in the CVE. Modern environments are exposed only if those old clients remain installed or unmanaged. Prioritize remediation if legacy FortiClient VPN software remains in use. The business risk is theft of VPN credentials, which can enable remote access compromise despite the absence of confirmed active exploitation in the supplied sources. Mitigation focus: Upgrade affected FortiClient products to versions at or above the CVE thresholds.; Check Fortinet/FortiGuard guidance for current supported remediation advice.; Remove unsupported legacy FortiClient and FortiClient Lite installations..
