How do I protect WAF 3.x from the Log4j vulnerability and ‘Log4Shell’ exploits?

    Description

    This article outlines configuration changes required on WAF 3.x to address the Log4j vulnerability.

    Resolution

    Although WAF 3.x uses Log4j, it only comes into action when enabled by the ‘Cloud Management’ feature.

    The ‘Cloud Management’ feature is disabled by default so customers are protected from the Log4j vulnerability.

    To avoid exploitation of the Log4j vulnerability customers should disable (uncheck) the ‘Cloud Management’ feature. Disabling the ‘Cloud Management’ feature won’t affect WAF functionality as ‘Cloud Management’ is a deprecated feature.

    A firmware upgrade on WAF is not required.

    To disable the 'Cloud Management' feature please go to System | Administration page:

    Image

    NOTE: WAF 2.2.x and earlier versions don’t use Log4j.
