CVE-2025-34231
Published: 29 September 2025
Summary
CVE-2025-34231 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Vasion Virtual Appliance Application. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 46.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 AC-4 (Information Flow Enforcement) and SC-7 (Boundary Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the CVE by requiring validation of user-controlled parameters used to build URLs before invoking processCurl() or file_get_contents(), preventing SSRF exploitation.
Enforces information flow control policies to block unauthorized outbound requests from the vulnerable script to internal resources, mitigating reconnaissance, leakage, pivoting, and exfiltration.
Monitors and controls communications at external and internal boundaries, preventing SSRF-induced requests from reaching or scanning internal networks.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unauthenticated SSRF in public-facing endpoint (T1190) enables internal network service discovery (T1046), use of the server as an internal proxy for pivoting (T1090.001), and exfiltration of internal data via SSRF responses (T1041), facilitating reconnaissance, credential leakage, pivoting, and data exfiltration.
NVD 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 blind and non-blind server-side request forgery (SSRF) vulnerability. The '/var/www/app/console_release/hp/badgeSetup.php' script is reachable from the Internet without any authentication…

and builds URLs from user‑controlled parameters before invoking either the custom processCurl() function or PHP’s file_get_contents(); in both cases the hostname/URL is taken directly from the request with no whitelist, scheme restriction, IP‑range validation, or outbound‑network filtering. Consequently, any unauthenticated attacker can force the server to issue arbitrary HTTP requests to internal resources. This enables internal network reconnaissance, credential leakage, pivoting, and data exfiltration. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.
Deeper analysisAI
CVE-2025-34231 is a blind and non-blind server-side request forgery (SSRF) vulnerability in Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 25.1.102 and Application versions prior to 25.1.1413, affecting both VA and SaaS deployments. The issue resides in the '/var/www/app/console_release/hp/badgeSetup.php' script, which is exposed to the internet without authentication. This script builds URLs directly from user-controlled parameters and invokes either the custom processCurl() function or PHP's file_get_contents() without whitelisting hostnames, scheme restrictions, IP-range validation, or outbound network filtering.
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction, achieving high-impact confidentiality breaches in a scoped context, as reflected in its CVSS v3.1 score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N). Exploitation forces the server to issue arbitrary HTTP requests to internal resources, enabling internal network reconnaissance, credential leakage, pivoting, and data exfiltration.
PrinterLogic security bulletins for SaaS and VA deployments, along with advisories from VulnCheck and researcher Pierre Kim, confirm the vulnerability has been remediated, though the specific version introducing the patch remains unclear. Security practitioners should upgrade to Virtual Appliance Host version 25.1.102 or later and Application version 25.1.1413 or later, and consult the referenced advisories for full details on mitigation.
This SSRF vulnerability is documented as part of 83 vulnerabilities identified by Pierre Kim in Vasion/PrinterLogic products.
