CVE-2024-1244

Improper input validation in the OSSEC HIDS agent for Windows prior to version 3.8.0 allows an attacker in with control over the OSSEC server or in possession of the agent's 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.

Summary		(es) La validación de entrada incorrecta en el agente HIDS de OSSEC para Windows (versión anterior a la 3.8.0) permite a un atacante con control sobre el servidor OSSEC o en posesión de la clave del agente configurarlo para que se conecte a una ruta UNC maliciosa. Esto provoca la filtración del hash NetNTLMv2 de la cuenta de la máquina, que puede retransmitirse para la ejecución remota de código o utilizarse para escalar privilegios al SYSTEM mediante la falsificación de certificados de AD CS y otros ataques similares.
