Low
← View More Security Advisories

Synopsis

Nessus versions 8.11.0 and earlier were found to be maintaining sessions longer than the permitted period in certain scenarios. The lack of proper session expiration could allow attackers with local access to login into an existing browser session.

Solution

Tenable has included a fix in Nessus 8.11.1 to address this issue. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus).
