Summary

CVE-2025-34228 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Vasion Virtual Appliance Application. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 49% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-34228 is a server-side request forgery (SSRF) vulnerability affecting Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 25.1.102 and Application versions prior to 25.1.1413 in VA/SaaS deployments. The vulnerable component is the `/var/www/app/console_release/lexmark/update.php` PHP script, which is exposed to the internet without authentication. This script constructs URLs from user-controlled input and executes them using `curl_exec()` or `file_get_contents()` without proper validation, allowing arbitrary request issuance by the server.

Any unauthenticated remote attacker can exploit this vulnerability over the network with low complexity, as indicated by its CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N) and associated CWEs-306 (Missing Authentication for Critical Function) and CWE-918 (SSRF). By supplying a malicious hostname, attackers can force the server to connect to internal resources, enabling network reconnaissance, lateral pivoting to other systems, or exfiltration of sensitive data from the internal network.

Vendor security bulletins for PrinterLogic SaaS and VA deployments, along with advisories from VulnCheck and researcher Pierre Kim, confirm the vulnerability has been remediated in later versions, though the exact patch introduction date remains unclear. Security practitioners should upgrade to Vasion Print Virtual Appliance Host 25.1.102 or later and Application 25.1.1413 or later, and verify exposure of the affected endpoint.

Vulnerability Data

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 `/var/www/app/console_release/lexmark/update.php` script is reachable from the internet without any authentication. The PHP script…

builds URLs from user‑controlled values and then invokes either 'curl_exec()` or `file_get_contents()` without proper validation. 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.

Mitigating Controls (NIST 800-53 r5) AI

Directly mandates unique identification and authentication of users before access to functions requiring identity.

Extends the same authentication requirement to non-organizational users accessing critical functionality.

Requires authentication of services before they can invoke or expose critical functions.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

PR.AA-03 full match
prevents

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.PS-06 mostly match
prevents

Secure development practices directly include input validation and destination allow-listing that prevent SSRF.

DE.CM-09 partial match
prevents

Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover and record SSRF flaws in web applications.

PR.AA-01 partial match
prevents

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.AA-05 partial match
prevents

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

prevents

The control explicitly calls for authentication before any critical function is reached, eliminating the possibility of bypassing authentication for high-value operations.

prevents

Operational threat data describing SSRF campaigns can be used to tighten outbound-request allow-lists and detection rules before attackers exploit them.

prevents

Mandating authentication requirements for critical functions at the requirements-gathering stage ensures that essential operations are not left unprotected by missing login or verification mechanisms.

mitigates

Mandating authentication for network services and critical functions stops attackers from invoking sensitive operations without credentials, closing gaps where authentication is absent for important capabilities.

prevents

Security engineering principles insist on authentication and authorization for every critical function, eliminating entry points that lack any access control mechanism.

none

Requiring strong authentication and access-privilege enablement for remote connections ensures that critical functions cannot be invoked without proper verification, closing a gap that would otherwise allow unauthenticated use.
