A Server-Side Request Forgery (SSRF) vulnerability in SMA1000 appliance firmware versions 12.4.3-02676 and earlier allows a remote, unauthenticated attacker to cause the SMA1000 server-side application to make requests to an unintended IP address.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
