Name of the Vulnerable Software and Affected Versions FortiOS versions prior to 7.2.5 FortiOS versions prior to 7.0.12 FortiOS versions prior to 6.4.13 FortiOS versions prior to 6.0.17 FortiProxy versions prior to 7.2.4 FortiProxy versions prior to 7.0.10 FortiProxy versions prior to 2.0.13 FortiProxy version 1.2 FortiProxy version 1.1

Description A heap-based buffer overflow in the SSL-VPN component may allow a remote attacker to execute arbitrary code or commands by sending specifically crafted requests. A heap-based buffer overflow occurs when a program writes more data to a heap memory block than it can hold, potentially corrupting memory and allowing for unauthorized code execution.

Recommendations As a temporary workaround, disable SSL-VPN. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
