A vulnerability in the clear audit log feature of ACOS software could allow a non-write privileged administrative user to clear the audit log. Additionally, in some circumstances, the action of clearing the audit log would not itself be subsequently logged. An attacker could exploit this vulnerability to mask evidence of prior malicious activity. Accordingly, the following vulnerabilities are addressed in this document.
