CVE-2024-1243Remote code execution and local privilege escalation in Wazuh Windows agent via NetNTLMv2 hash theft
Critical 9.5
In plain English
A critical-severity improper input validation in Wazuh Agent from Wazuh. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.6% (higher than 51% of all known vulnerabilities).
Official description
Improper input validation in the Wazuh agent for Windows prior to version 4.8.0 allows an attacker with control over the Wazuh server or agent key to configure the agent to connect to a malicious UNC path. This results in the leakage of the machine account NetNTLMv2 hash, which can be relayed for remote code execution or used to escalate privileges to SYSTEM via AD CS certificate forging and other similar attacks.
