Summary

CVE-2025-34206 is a critical-severity Cleartext Storage of Sensitive Information (CWE-312) vulnerability in Vasion Virtual Appliance Application. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 39th 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 map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — 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-2025-34206 is a critical vulnerability in Vasion Print (formerly PrinterLogic) Virtual Appliance Host and Application, affecting both VA and SaaS deployments. It stems from the mounting of host configuration and secret material under /var/www/efs_storage into numerous Docker containers using overly-permissive filesystem permissions. This exposure includes sensitive files such as secrets.env, GPG-encrypted blobs in .secrets, MySQL client keys, and application session files, which become accessible across multiple containers. The issue is classified under CWE-312 (Cleartext Storage of Sensitive Information) and CWE-732 (Incorrect Permission Assignment for Critical Resource), with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

An attacker who gains control of or reaches any affected Docker container can read or modify these exposed artifacts. Potential impacts include credential theft, remote code execution through manipulation of the Laravel APP_KEY, takeover of Portainer for container orchestration, and full compromise of the environment. The vulnerability requires no privileges or user interaction and is exploitable over the network with low complexity.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the access control policy that defines permissions on resources, thereby stopping incorrect assignments from remaining exploitable.

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

Directly requires assignment of only the minimum necessary permissions, preventing overly broad grants on critical resources.

Directly requires defining, enforcing, and reviewing access permissions and least privilege on resources.

PR.DS-01 full match
prevents

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

PR.PS-01 mostly match
prevents

Hardened baselines and configuration management explicitly include correct permission settings for critical resources.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.

prevents

Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.

prevents

Documented authorization, expiry rules, and audit logging of privileged accounts make it harder for critical resources to retain overly permissive or stale permission assignments.

prevents

Requiring explicit configuration of access controls and permissions for files, applications and services counters the assignment of overly permissive default or incorrect file-system rights.

prevents

Enforcing differentiated permissions on the source-code repository and program listings stops the assignment of overly broad default or inherited permissions to critical resources.

prevents

By defining and enforcing secure permission settings in configuration templates, the control reduces the likelihood that critical resources receive incorrect permission assignments.
