CVE-2025-34192 is a critical vulnerability identified in Vasion Print Virtual Appliance Host versions prior to 22.0.893 and Application versions prior to 20.0.2140 (macOS/Linux clients). These versions rely on OpenSSL 1.0.2h-fips, a cryptographic library released in May 2016 and declared end-of-life in 2019. Since OpenSSL 1.0.2h-fips is no longer supported, any vulnerabilities discovered after its end-of-life remain unpatched, exposing systems to known cryptographic weaknesses. The use of this unmaintained third-party component (CWE-1104) results in potential security flaws in TLS/SSL processing and cryptographic operations, which attackers could exploit remotely without any authentication or user interaction. The affected daemons may emit deprecation warnings but continue to operate with vulnerable cryptographic functions. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges or user interaction required (PR:N/UI:N), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no exploits have been observed in the wild yet, the vulnerability's criticality demands urgent attention. The vendor has acknowledged the issue as V-2023-021 but has not yet provided patch links, emphasizing the need for organizations to proactively manage risk. This vulnerability undermines the security posture of Vasion Print deployments, potentially allowing attackers to intercept or manipulate sensitive print job data or disrupt printing services.

For European organizations, the impact of CVE-2025-34192 is significant due to the critical role printing infrastructure plays in business operations and document handling. Exploitation could lead to unauthorized disclosure of sensitive information transmitted via print jobs, manipulation or interception of print data, and denial of service conditions affecting printing availability. This is particularly concerning for sectors handling confidential or regulated data such as government agencies, financial institutions, healthcare providers, and large enterprises. The vulnerability's remote exploitability without authentication increases the attack surface, enabling external threat actors to target exposed Vasion Print appliances directly. Compromise could facilitate lateral movement within networks or serve as a foothold for further attacks. Additionally, the use of outdated cryptography may conflict with European data protection regulations (e.g., GDPR) that mandate strong security controls, potentially exposing organizations to compliance risks and reputational damage.

1. Immediately inventory all Vasion Print Virtual Appliance Host and Application deployments to identify affected versions. 2. Engage with Vasion for official patches or updated versions that replace the outdated OpenSSL library; prioritize upgrading to versions 22.0.893 or later for the appliance and 20.0.2140 or later for macOS/Linux clients. 3. If patches are not yet available, isolate vulnerable appliances from untrusted networks and restrict access using network segmentation and firewall rules. 4. Monitor network traffic for unusual TLS/SSL activity or anomalies that could indicate exploitation attempts, using intrusion detection/prevention systems tuned for cryptographic protocol anomalies. 5. Implement compensating controls such as VPN tunnels or encrypted channels external to the vulnerable appliance to protect print data in transit. 6. Review and update cryptographic policies to disallow deprecated protocols and ciphers. 7. Conduct regular vulnerability scanning and penetration testing focused on print infrastructure. 8. Maintain an incident response plan tailored to potential exploitation scenarios involving print services. 9. Educate IT and security teams about the risks of using unmaintained third-party components and enforce strict software lifecycle management practices.
