Technical details

A Server-Side Request Forgery (SSRF) vulnerability (CWE-918) exists in the Work Place interface of SonicWall SMA1000 appliances. The flaw allows a remote, unauthenticated attacker to send crafted requests that force the appliance to initiate outbound network connections to arbitrary destinations. This can be leveraged to scan internal network segments, interact with internal services behind the firewall, or potentially exfiltrate sensitive metadata. The vulnerability affects specific firmware versions in the 12.4.3 and 12.5.0 branches. Users are advised to consult SonicWall's PSIRT for specific patch availability.
