[R1] Tenable.sc 5.20.0 Fixes Multiple Vulnerabilities
Critical
Synopsis
Tenable.sc versions 5.14.0 through 5.19.1 were found to contain a remote code
execution vulnerability which could allow a remote, unauthenticated attacker to
execute code under special circumstances. An attacker would first have to stage
a specific file type in the web server root of the Tenable.sc host prior to
remote exploitation.
Also, Tenable.sc leverages third-party software to help provide underlying
functionality. One of the third-party components (Apache) was found to contain
vulnerabilities, and updated versions have been made available by the
providers.
Out of caution, and in line with best practice, Tenable has upgraded the
bundled components to address the potential impact of these issues. Tenable.sc
5.20.0 updates Apache to version 2.4.52 to address the identified
vulnerabilities.
Solution
Tenable has released Tenable.sc 5.20.0 to address these issues. The
installation files can be obtained from the Tenable Downloads Portal ( https://
www.tenable.com/downloads/tenable-sc ).
