DriveLock Agent Authentication Bypass Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2025-67791

The vulnerability involves authentication between DriveLock agents and the DriveLock Enterprise Service (DES). While these components communicate over a network, they are typically deployed within an internal, managed enterprise environment rather than being directly exposed to the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

An issue in DriveLock's enterprise service allows attackers to impersonate legitimate agents, potentially leading to unauthorized access and control if exploited. The primary concern is confirming the relevance and exposure of this vulnerability within your environment.

Attackers can impersonate trusted agents.
Protects sensitive system configurations and data.
Assess if DriveLock is used and if agents are protected.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by impersonating a DriveLock agent on the network, leveraging an incomplete agent authentication configuration to gain unauthorized access to the DriveLock Enterprise Service. This could allow them to manipulate or access sensitive data and systems managed by DriveLock.

Requires network access and no user interaction.
Triggered by an incomplete agent authentication setup.
Risk of unauthorized agent impersonation and data compromise.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, an incomplete agent authentication configuration in DriveLock tenants could allow an attacker to impersonate any DriveLock agent on the network when interacting with the DriveLock Enterprise Service.

Unauthorized administrative control.

Operational Fix

Recommended remediation, mitigation, and detection steps

Security teams and platform owners are likely responsible for addressing this critical vulnerability in the DriveLock Enterprise Service. The immediate first step is to inventory all DriveLock agent and DES instances, determine their network reachability and business criticality, and identify the specific system owners accountable for each. A phased remediation plan, prioritizing the most exposed or critical systems, should then be developed and executed.

Assign ownership to security and platform teams.
Verify agent and DES instance reachability.
Plan remediation based on exposure and criticality.

Frequently asked questions

What is DriveLock?

DriveLock is an endpoint security software suite designed to manage device control, application security, and full-disk encryption. It uses a central component called the DriveLock Enterprise Service (DES) to coordinate policies and monitor status across various devices within an organization. Agents installed on individual computers or servers communicate with the DES to receive instructions and report system activity.

What does CWE-287 mean for CVE-2025-67791?

CWE-287 refers to Improper Authentication. In the context of CVE-2025-67791, this means the system fails to correctly verify the identity of an entity before granting access. Because of an incomplete configuration in how DriveLock tenants handle agent authentication, the system cannot reliably distinguish between a legitimate agent and an unauthorized party, allowing an attacker to impersonate a trusted agent.

How is this vulnerability triggered?

An attacker triggers this bug by communicating directly with the DriveLock Enterprise Service while impersonating a legitimate agent. This vulnerability does not require any specific action or interaction from a user on the system. It specifically results from an incomplete authentication configuration within the tenant setup; it is not triggered by standard, correctly configured agent-to-server communication.

Is my network vulnerable to CVE-2025-67791?

According to Halo Surface Signal, this vulnerability is considered unlikely to be directly reachable from the public internet. DriveLock agents and the Enterprise Service are typically deployed within internal, managed enterprise networks. While an attacker needs network access to attempt this, your primary concern should be internal systems where agents communicate with the DES over your local infrastructure.

What should I do to address this issue?

Start by identifying all deployed DriveLock agents and DES instances in your environment. Confirm the current software version for each, as the vulnerability affects specific versions from 24.1 through 25.1. Once identified, consult the official vendor documentation provided in the security bulletin to apply the necessary configuration updates or patches to secure the agent authentication process.
