CVE-2025-34229: CWE-306 Missing Authentication for Critical Function in Vasion Print Virtual Appliance Host
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/hp/installApp.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://<host‑address>: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.
AI Analysis
Technical Summary
Vasion Print Virtual Appliance Host versions before 25.1.102 and Application versions before 25.1.1413 contain a blind SSRF vulnerability in the /var/www/app/console_release/hp/installApp.php script. When registering a printer, the software stores the printer's host name and later constructs a URL using this host name to send an HTTP request via curl without validating or filtering the host address. This lack of authentication and input validation allows unauthenticated attackers to cause the server to send requests to arbitrary hosts, potentially probing internal network services or triggering internal actions. The vulnerability is tracked as CWE-306 (Missing Authentication for Critical Function) and CWE-918 (Server-Side Request Forgery). The CVSS v4.0 base score is 6.9, indicating medium severity. The vulnerability has been confirmed as fixed, though the exact patch version or date is not specified.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to cause the vulnerable server to send HTTP requests to arbitrary hosts, including internal network services. This can be used to gather intelligence about internal network topology or trigger internal actions. The blind nature of the SSRF means the attacker does not receive direct response data, limiting the impact to indirect probing or triggering. There are no known exploits in the wild. The vulnerability does not require user interaction or privileges.
Mitigation Recommendations
The vulnerability has been confirmed as remediated by the vendor, though the exact patch version or date is not specified. Users should upgrade to Vasion Print Virtual Appliance Host version 25.1.102 or later and Application version 25.1.1413 or later to ensure the fix is applied. Until upgraded, restrict access to the vulnerable script and monitor for suspicious activity related to SSRF attempts. Check the vendor advisory or contact Vasion support for the precise patch details and remediation guidance.
