Descriptions

Under certain conditions, Nessus Network Monitor could allow a low privileged user to escalate privileges to NT AUTHORITY\SYSTEM on Windows hosts by replacing a specially crafted file.

Bajo ciertas condiciones, Nessus Network Monitor podría permitir que un usuario con pocos privilegios escale privilegios a NT AUTHORITY\SYSTEM en hosts de Windows reemplazando un archivo especialmente manipulado.

This vulnerability allows local attackers to escalate privileges on affected installations of Tenable Nessus Network Monitor. 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 configuration of OpenSSL. The process loads an OpenSSL configuration file from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
