Technical ContextAI · show details
This vulnerability is classified as Missing Authentication for Critical Function (CWE-306), which allows attackers to access critical functionality without authentication. Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to 22.0.1049 and Application prior to 20.0.2786 (VA and SaaS deployments) configure the SSH client within Docker instances with the following options: UserKnownHostsFile=/dev/null, StrictHostKeyChecking=no, and ForwardAgent yes. These settings disable verification of the remote host’s SSH key and automatically forward the developer’s SSH‑agent to any host that matches the configured wildcard patterns. As a result, an attacker who can reach a single compromised container can cause the container to connect to a malicious SSH server, capture the forwarded private keys, and use those keys for unrestricted lateral movement across the environment. This vulnerability has been identified by the vendor as: V-2024-027 - Insecure Secure Shell (SSH) Configuration. Affected products include: Vasion Virtual Appliance Application, Vasion Virtual Appliance Host. Version information: prior to 22.0.1049.

Executive ViewAI
CVE-2025-34207 presents notable security risk, a missing authentication vulnerability rated CVSS 7.9. Attackers could bypass security controls to gain unauthorized access to protected resources and sensitive data. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls; (2) Enable MFA where possible; (3) Monitor authentication logs for anomalous access.
