Print Virtual Appliance Host: Server-Side Request Forgery
CVE-2025-34225 is a high-severity server-side request forgery vulnerability in Print Virtual Appliance Host from Vasion, with a CVSS 3.1 base score of 8.6 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 25.1.102 as the first without the flaw, so updating Print Virtual Appliance Host to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.81% chance of exploitation within 30 days, higher than 58% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Print Virtual Appliance Host to 25.1.102 or a later version.
- Update Print Application to 25.1.1413 or a later version.
- Update Virtual Appliance Application to 25.1.1413 or a later version.
- Read the advisory on help.printerlogic.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
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 server-side request forgery (SSRF) vulnerability. The `console_release` directory is reachable from the internet without any authentication. Inside that directory are dozens of PHP scripts that build URLs from user‑controlled values and then invoke either 'curl_exec()` or `file_get_contents()` without proper validation. Although many files attempt to mitigate SSRF by calling `filter_var', the checks are incomplete. Because the endpoint is unauthenticated, any remote attacker can supply a hostname and cause the server to issue requests to internal resources. This enables internal network reconnaissance, potential pivoting, or data exfiltration. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.

The underlying weakness: Server-Side Request Forgery
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.
How developers prevent this class of flaw
- If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
- If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
