CVE-2025-34198: Vasion Virtual Appliance Application

Critical severity, CVSS 9.8. EPSS: 0.8% chance of exploitation in the next 30 days.

Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.951 and Application prior to 20.0.2368 (VA and SaaS deployments) contain shared, hardcoded SSH host private keys in the appliance image. The same private host keys (RSA, ECDSA, and ED25519) are present across installations, rather than being uniquely generated per appliance. An attacker who obtains these private keys (for example from one compromised appliance image or another installation) can impersonate the appliance, decrypt or intercept SSH connections to appliances that use the same keys, and perform man-in-the-middle or impersonation attacks against administrative SSH sessions. This vulnerability has been identified by the vendor as: V-2024-011 — Hardcoded SSH Host Key.

Affected products

• Vasion Virtual Appliance Application: before 20.0.2368 (fixed in 20.0.2368)
• Vasion Virtual Appliance Host: before 22.0.951 (fixed in 22.0.951)
