The manipulation of the argument printer_vo with an unknown input leads to a missing authentication vulnerability. The CWE definition for the vulnerability is CWE-306. The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (VA/SaaS deployments) contain a blind server-side request forgery (SSRF) vulnerability reachable via the /var/www/app/console_release/lexmark/dellCheck.php script that can be exploited by an unauthenticated user. When a printer is registered, the software stores the printer’s host name in the variable $printer_vo->str_host_address. The code later builds a URL like 'http://:80/DevMgmt/DiscoveryTree.xml' and sends the request with curl. No validation, whitelist, or private‑network filtering is performed before the request is made. Because the request is blind, an attacker cannot see the data directly, but can still: probe internal services, trigger internal actions, or gather other intelligence. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.
