Attackers can redirect requests from the Sonicwall SMA1000 remote access solution. A security patch provides a remedy.
Manipulated connections
In a warning message, the network technology provider explains that attackers can redirect requests to servers they control (CVE-2025-40595 “high”) as part of a server-side request forgery (SSRF) attack.
In the context of a remote access solution, which employees are supposed to use to establish secure connections with their devices, this can have far-reaching consequences. Attacks should be possible remotely and without authentication.

So far, there have been no reports of ongoing attacks. Network admins should nevertheless react promptly and install version 12.4.3-02963 (platform-hotfix) to close the gap in the appliance work-place interface.
