CVE-2025-67791 is a security vulnerability identified in multiple versions of DriveLock, specifically versions 24.1 through 24.1.*, 24.2 through 24.2.*, and 25.1 through 25.1.*. The root cause is an incomplete configuration related to agent authentication within the DriveLock tenant environment. DriveLock agents communicate with the DriveLock Enterprise Service (DES) to enforce endpoint security policies and data protection. Due to this incomplete authentication setup, an attacker with network access can impersonate any DriveLock agent on the network. This impersonation allows the attacker to potentially bypass security controls, manipulate endpoint policies, or gain unauthorized access to sensitive data managed by DriveLock. The vulnerability does not require user interaction but does require network access to the DES. No public exploits have been reported yet, and no official CVSS score has been assigned. The lack of agent authentication means that the trust model between agents and the DES is broken, which can lead to significant security breaches if exploited. DriveLock is widely used in enterprise environments, especially in Europe, for endpoint protection and data loss prevention, making this vulnerability particularly concerning for organizations relying on this product for compliance and security.

For European organizations, the impact of CVE-2025-67791 can be substantial. DriveLock is commonly deployed in regulated industries such as finance, healthcare, and manufacturing, where endpoint security and data protection are critical. Successful exploitation could allow attackers to impersonate legitimate security agents, potentially disabling or altering security policies, exfiltrating sensitive data, or spreading malware undetected. This compromises confidentiality, integrity, and availability of protected systems. The breach of endpoint security controls could lead to regulatory non-compliance, financial losses, reputational damage, and operational disruption. Since the vulnerability requires network access but no user interaction, insider threats or attackers who have gained initial footholds in the network could escalate privileges or move laterally more easily. The absence of known exploits provides a window for proactive defense, but organizations must act swiftly to prevent exploitation.

Organizations should immediately review and correct the agent authentication configuration within their DriveLock tenant to ensure that all agents are properly authenticated before communicating with the DES. Network segmentation should be enforced to limit access to the DriveLock Enterprise Service to only authorized systems. Monitoring and logging of agent communications should be enhanced to detect any anomalous or unauthorized impersonation attempts. Although no patches are currently available, organizations should stay alert for vendor updates or security advisories and apply patches promptly once released. Conducting internal penetration testing or red team exercises to simulate agent impersonation attacks can help validate defenses. Additionally, implementing multi-factor authentication and strict access controls for network segments hosting DriveLock components can reduce the risk of exploitation. Finally, educating IT and security teams about this vulnerability will improve incident response readiness.
