Improper access control vulnerability in the repair process for McAfee Agent for Windows prior to 5.7.4 could allow a local attacker to perform a DLL preloading attack using unsigned DLLs. This would result in elevation of privileges and the ability to execute arbitrary code as the system user, through not correctly protecting a temporary directory used in the repair process and not checking the DLL signature.
Una vulnerabilidad de control de acceso inapropiado en el proceso de reparación de McAfee Agent para Windows versiones anteriores a 5.7.4, podría permitir a un atacante local llevar a cabo un ataque de precarga de DLL usando DLL sin firmar. Esto daría lugar a una elevación de privilegios y a la posibilidad de ejecutar código arbitrario como usuario del sistema, al no proteger correctamente un directorio temporal usado en el proceso de reparación y no comprobar la firma de la DLL
This vulnerability allows local attackers to escalate privileges on affected installations of McAfee Endpoint Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the installer. The issue results from incorrect permissions set on a resource used by the installer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
