Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the Wazuh Agent, an open-source platform for threat detection, could allow authenticated attackers to exploit NTLM authentication to escalate privileges and execute remote code. This issue has been addressed in version 4.13.0. The main concern at this time is to confirm if this specific technology is in use and if so, assess its exposure.
- Allows attackers to gain system control.
- Potentially serious security control bypass.
- Confirm use and evaluate exposure.
Attack Path
How an attacker could exploit the issue
An attacker with existing privileged access to a Wazuh agent can initiate a connection to a malicious server by crafting specific configuration settings. This allows the attacker to trick the agent into authenticating to their controlled server using NTLM. If successful, this can lead to privilege escalation or remote code execution on the affected system.
- Requires authenticated agent access.
- Triggers NTLM authentication via UNC paths.
- Leads to privilege escalation and RCE.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, authenticated attackers could force NTLM authentication through malicious UNC paths in Wazuh Agent configurations. This could lead to NTLM relay attacks that escalate privileges and allow remote code execution on affected systems.
- Wazuh agent authentication credentials.
-Malicious UNC paths in agent configurations. -Privilege escalation and remote code execution.
Operational Fix
Recommended remediation, mitigation, and detection steps
Action for this CVE advisory primarily falls to teams managing Wazuh deployments, which may include security operations, infrastructure, or platform engineering. The initial practical step is to identify all systems running the affected Wazuh Agent, confirm their business criticality and network exposure, and then engage the accountable owners to plan remediation.
- Platform or Security Operations teams own this.
- Verify agent deployment and network reachability.
- Plan phased upgrades during maintenance windows.
