Operating System Unsupported Version Detection in banner reporting (PCI-DSS check)

Critical Nessus Plugin ID 122403


The OS version reported in banners possesses one or more vulnerabilities.


A service banner response from the remote host indicates an operating system install at a level that indicates the operating system running on the remote host is no longer supported.

Lack of support implies that no new security patches for the product will be released by the vendor. As a result, it is likely to contain security vulnerabilities.

This plugin only runs when 'Check for PCI-DSS compliance' is enabled in the scan policy. It does not run if local security checks are enabled. It runs off of self-reported OS versions in banners and fingerprinting.


Upgrade to a version of the operating system that is currently supported.
