[R1] LCE 6.0.9 Fixes Multiple Third-party Vulnerabilities

High

Synopsis

Tenable Log Correlation Engine leverages third-party software to help provide
underlying functionality. Two separate third-party components (OpenSSL, jQuery)
were found to contain vulnerabilities, and updated versions have been made
available by the providers.

Out of caution and in line with good practice, Tenable opted to upgrade the
bundled OpenSSL and jQuery components to address the potential impact of these
issues. LCE 6.0.9 updates OpenSSL to version 1.1.1k and jQuery to version 3.5.1
to address the identified vulnerabilities.

Solution

Tenable has released Log Correlation Engine 6.0.9 to address these issues. The
installation files can be obtained from the Tenable Downloads Portal ( https://
www.tenable.com/downloads/log-correlation-engine ).

This page contains information regarding security vulnerabilities that may
impact Tenable's products. This may include issues specific to our software, or
due to the use of third-party libraries within our software. Tenable strongly
encourages users to ensure that they upgrade or apply relevant patches in a
timely manner.

Tenable takes product security very seriously. If you believe you have found a
vulnerability in one of our products, we ask that you please work with us to
quickly resolve it in order to protect customers. Tenable believes in
responding quickly to such reports, maintaining communication with researchers,
and providing a solution in short order.
