Custom audit files bring tremendous power and flexibility when assessing the configuration of your assets. Two separate vulnerabilities that utilize this custom Audit functionality were identified, reported and fixed. With the release of Nessus Agent 8.3.4, Tenable has mitigated the reported issues by enabling the ability to sign and verify custom audit files.
1. CVE-2022-32973 – An authenticated attacker could create an audit file that bypasses PowerShell cmdlet checks and executes commands with administrator privileges.
2. CVE-2022-32974 – An authenticated attacker could read arbitrary files from the underlying operating system of the scanner using a custom crafted compliance audit file without providing any valid SSH credentials.
