A path traversal vulnerability in Tenable Agent 11.2.0 and 11.1.3 and lower allows a privileged attacker to write arbitrary files outside the intended plugin directory, potentially leading to remote code execution.
This vulnerability allows an attacker to create a junction, enabling the deletion of arbitrary files with SYSTEM privileges. As a result, this condition potentially facilitates arbitrary code execution, whereby an attacker may exploit the vulnerability to execute malicious code with elevated SYSTEM privileges.
A vulnerability has been identified where weak file permissions in the Nessus Agent directory on Windows hosts could allow unauthorized access, potentially permitting Denial of Service (DoS) attacks.
In Tenable Agent versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could arbitrarily delete local system files with SYSTEM privilege, potentially leading to local privilege escalation.
In Tenable Agent versions prior to 10.8.5 on a Windows host, it was found that a non-administrative user could overwrite arbitrary local system files with log content at SYSTEM privilege.
