Nessus Network Monitor < 6.5.1 Multiple Vulnerabilities (TNS-2025-10)

high Nessus Plugin ID 237289

Language:

Synopsis

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

Description

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2025-10 advisory.

 - In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used. (CVE-2025-32415)

 - 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)

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

Solution

Upgrade to Nessus Network Monitor 6.5.1 or later.
