Summary

CVE-2025-34216 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Vasion Virtual Appliance Application. Its CVSS base score is 10.0 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 48% 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 IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

CVE-2025-34216 affects Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.1026 and Application versions prior to 20.0.2702, specifically in VA deployments. The vulnerability involves unauthenticated REST API endpoints that expose configuration files, clear-text passwords, and the Laravel APP_KEY used for cryptographic signing. This issue, identified by the vendor as V-2024-018 (RCE & Leaks via API), is rated at CVSS 9.8 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and maps to CWEs 306 (Missing Authentication for Critical Function) and 312 (Cleartext Storage of Sensitive Information).

Any unauthenticated remote attacker can exploit these endpoints over the network with low complexity and no privileges required. By retrieving the APP_KEY, the attacker can forge valid signed requests to the application, enabling remote code execution on the appliance. Additionally, the exposure of clear-text passwords provides immediate access to credentials for further compromise.

Vendor security bulletins at help.printerlogic.com detail mitigation through upgrading to Virtual Appliance Host version 22.0.1026 or later and Application version 20.0.2702 or later. Independent advisories from VulnCheck and researcher Pierre Kim confirm the issue and emphasize patching as the primary remediation, with no workarounds specified for affected versions.

Vulnerability Data

Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1026 and Application prior to version 20.0.2702 (VA deployments only) expose a set of unauthenticated REST API endpoints that return configuration files and clear‑text passwords. The same endpoints also disclose…

more

the Laravel APP_KEY used for cryptographic signing. Because the APP_KEY is required to generate valid signed requests, an attacker who obtains it can craft malicious payloads that are accepted by the application and achieve remote code execution on the appliance. This vulnerability has been identified by the vendor as: V-2024-018 — RCE & Leaks via API.

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.

SC-28 requires cryptographic or equivalent protection of sensitive data at rest, directly stopping cleartext storage in accessible resources.

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

Access enforcement requires prior authentication before any authorization decision for critical functions.

PR.AA-03 full match
prevents

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

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

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.

PR.IR-01 partial match
prevents

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

prevents

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

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

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

mitigates

Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.

A.8.11 Data masking partial match
mitigates

Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.
