[R1] Tenable Network Monitor Version 6.5.1 Fixes Multiple Vulnerabilities

High
← View More Security Advisories

Synopsis

Tenable Network Monitor leverages third-party software to help provide underlying functionality. Several of the third-party components (OpenSSL, expat, curl, libpcap, libxml2) were 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 opted to upgrade these components to address the potential impact of the issues. Tenable Network Monitor 6.5.1 updates OpenSSL to version 3.0.16, expat to version 2.7.0, curl to version 8.12.0, libpcap to version 1.10.5 and libxml2 to to version 2.13.8 to address the identified vulnerabilities.

Additionally, two separate vulnerabilities were discovered, reported and fixed:

  • When installing Tenable Network Monitor to a non-default location on a Windows host, Tenable Network Monitor versions prior to 6.5.1 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location. - CVE-2025-24916
  • In Tenable Network Monitor versions prior to 6.5.1 on a Windows host, it was found that a non-administrative user could stage files in a local directory to run arbitrary code with SYSTEM privileges, potentially leading to local privilege escalation. - CVE-2025-24917

Solution

Tenable has released Tenable Network Monitor 6.5.1 to address these issues. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus-network-monitor).
