[R1] Nessus Versions 8.15.3 and 10.1.1 Fix Multiple Third-Party Vulnerabilities

Critical
← View More Security Advisories

Synopsis

Nessus leverages third-party software to help provide underlying functionality. One of the third-party components (Expat) was found to contain vulnerabilities, and an updated version has been made available by the provider.

Out of caution and in line with best practice, Tenable has opted to upgrade the Expat component to address the potential impact of the issue. Nessus 10.1.1 and Nessus 8.15.3 update Expat to version 2.4.4 to address the identified vulnerability.

Solution

Tenable has released Nessus 10.1.1 and Nessus 8.15.3 to address these issues. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus).
