A Server-Side Request Forgery (SSRF) vulnerability has been identified in the embedded web server in various Lexmark devices. This vulnerability can be leveraged by an attacker to force the device to send an arbitrary HTTP request to a third-party server. Successful exploitation of this vulnerability can lead to internal network access / potential data disclosure from a device.
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.
