An Exposure of Sensitive Information to an Unauthorized Actor vulnerability [CWE-200] in FortiOS SSL-VPN may allow a remote unauthenticated attacker to bypass the patch developed for the symbolic link persistency mechanism observed in some post-exploit cases, via crafted HTTP requests. An attacker would need first to have compromised the product via another vulnerability, at filesystem level.
This vulnerability can only be abused as a consequence of a threat actor exploiting a known vulnerability to implement read-only access to vulnerable FortiGate devices, at file system level.
Products that never had SSL-VPN enabled, are not impacted by this issue.
Virtual Patch named "FG-VD-60389.0day." is available in FMWP db update 26.033
