CVE-2025-34232: Vasion Print (formerly PrinterLogic) Blind SSRF via Lexmark dellCheck.php
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://<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.
Security readout for executives and security teams
Plain-English summary
CVE-2025-34232 lets an unauthenticated attacker make Vasion Print send hidden web requests from the server to other systems. The attacker does not directly see responses, but could map internal services or trigger reachable internal endpoints. This matters most where Vasion Print can reach sensitive internal networks.
Executive priority
Treat as a timely patch and network-containment item, not an emergency unless Vasion Print can reach sensitive internal services. Prioritize internet-exposed or broadly reachable deployments first.
Technical view
The issue is a blind SSRF in /var/www/app/console_release/lexmark/dellCheck.php. A stored printer host address is inserted into an HTTP URL and requested with curl without validation, allowlisting, or private-network filtering. Sources identify CWE-918 and CWE-306, CVSS 4.0 score 6.9.
Likely exposure
Exposure is likely limited to organizations running Vasion Print Virtual Appliance Host before 25.1.102 or Print Application before 25.1.1413 in VA or SaaS deployments, especially if unauthenticated users can reach printer registration-related functionality.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. The vulnerability is network-reachable, unauthenticated, and low-complexity, but blind SSRF limits direct data return. Practical risk depends on internal services reachable from the Vasion Print server.
Researcher notes
The key sink is curl requesting http://<printer-host>:80/DevMgmt/DiscoveryTree.xml using $printer_vo->str_host_address without host validation or private-network filtering. Avoid assuming data exfiltration from the SSRF alone because the cited issue is blind.
Mitigation direction
Upgrade Vasion Print VA Host to 25.1.102 or later.
Upgrade Vasion Print Application to 25.1.1413 or later.
Review Vasion security bulletins for deployment-specific guidance.
Restrict unauthenticated access to printer registration-related surfaces where possible.
Limit outbound access from Vasion systems to required destinations only.
Monitor Vasion systems for unexpected outbound HTTP to internal hosts.
Validation and detection
Inventory Vasion Print VA and SaaS deployment versions.
Compare installed versions with Vasion security bulletins.
Review web logs for requests to the Lexmark dellCheck.php path.
Review outbound telemetry from Vasion hosts to unexpected internal services.
Confirm upgraded deployments no longer accept unsafe printer host inputs.

CWE-306: Credential and account abuse lookup
Authentication and credential weaknesses can make valid-account abuse and credential telemetry useful review starting points. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
CWE-918: Information exposure and cloud metadata lookup
Information exposure and SSRF weaknesses can make discovery, cloud metadata, and credential material review relevant. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references SSRF or metadata access, so cloud discovery and credential material review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
