    HI Community Members,

    I wanted to ask if Incapsula is providing off-the-shelf protection against CVE-2020-5902? Do i need to create any custom rules for this?

    Hi Nikhil,
    Although this CVE refers to a vulnerability found in F5 devices only, given a case that such device is behind our Cloud WAF, it will be blocked out of the box.

    Hi Nikhil,

    While the CVE-2020-5902 is blocked by Imperva, pls review your setup
    - is the site has IRA blocked in WAF setting?
    - is the Origin open to Internet if not add only Imperva IP to reach Origin?
    - Is F5 before FW or self or TMUI port was open to internet ?
    From their KB - https://support.f5.com/csp/article/K52145254
    Important: If your BIG-IP system has TMUI exposed to the Internet and it does not have a patched version of software installed, there is a high probability that it has been compromised and you should follow your internal incident response procedures. Please see the Indications of compromise section below.
    Note: Authenticated users accessing the Configuration utility will always be able to exploit this vulnerability until a fixed release is installed.
    Review SIEM for /tmui and check the response and best reach out to F5 support for latest update.

    Thanks
    Abhishek
