RSA Authentication Manager

RSA Authentication Manager does not use PHP and is not affected by these vulnerabilities. Security scanners may flag files that are present but unused, such as process-request.php sample files from the ExtJS RemoteTree extension included in the bundled UI toolkit library, and standard SUSE Linux operating system files, including the macros.php RPM build-macro file and the x-php.xml MIME type definition. None of these files is executed or served by Authentication Manager.

Customers are not required to take any action, including applying product updates or making configuration changes.

Customers using PHP outside of RSA products should contact their respective provider for recommendations on supported updates.
