**How could an attacker exploit this vulnerability?** Exploitation of this vulnerability requires that an attacker send a malicious link to the victim via email, or that they convince the user to click the link, typically by way of an enticement in an email or Instant Messenger message. In the worst-case email attack scenario, an attacker could send a specially crafted email to the user without a requirement that the victim open, read, or click on the link. This could result in the attacker executing remote code on the victim's machine. When multiple attack vectors can be used, we assign a score based on the scenario with the higher risk (UI:N).

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.
