Kiteworks Email Protection Gateway versions prior to 9.5.0
Description
A Server-Side Request Forgery (SSRF) weakness allows a remote, unauthenticated attacker to force the gateway to send crafted requests to internal or unintended network destinations. This occurs when the gateway performs an online certificate status check for an inbound message. Depending on the reachable services, this could lead to the disclosure of sensitive internal information or the disruption of gateway operations.
Recommendations
Update Kiteworks Email Protection Gateway to version 9.5.0 or later.
Fix
SSRF
