Nessus Network Monitor < 6.3.1 Multiple Vulnerabilities (TNS-2023-43)

critical Nessus Plugin ID 186472


An instance of Tenable NNM installed on the remote system is affected by multiple vulnerabilities.


According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.3.1. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-43 advisory.

- Nessus Network Monitor leverages third-party software to help provide underlying functionality. Several of the third-party components (HandlebarsJS, OpenSSL, and jquery-file-upload)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. Nessus Network Monitor 6.3.1 updates HandlebarsJS to version 4.7.8, OpenSSL to version 3.0.12, and jquery-file-upload to version 10.8.0. Tenable has released Nessus Network Monitor 6.3.1 to address these issues. The installation files can be obtained from the Tenable Downloads Portal ( (CVE-2018-9206, CVE-2021-23369, CVE-2021-23383, CVE-2023-5363)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Nessus Network Monitor 6.3.1 or later.
