Microsoft XML Parser (MSXML) and XML Core Services Unsupported

critical Nessus Plugin ID 62758


The remote Windows host contains unsupported XML parsers.


The remote host contains one or more unsupported versions of the Microsoft XML Parser (MSXML) or XML Core Services.

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.

Note that support for MSXML 3.0 and 6.0 is based on the support policy of the operating system on which it is installed. Support for MSXML 5.0 is based on the Microsoft Office lifecycle policy.


Upgrade the software packages responsible for the unsupported DLL versions or upgrade to a supported version of Windows (Vista / 2008 or later). Alternatively, uninstall the outdated MSXML or XML Core Services.
