What is CVE-2019-3928?

The Crestron AM-100 and AM-101 devices are vulnerable to an authentication bypass flaw that enables unauthorized users to retrieve the presentation passcode. This vulnerability arises from how the devices handle certain OIDs (Object Identifiers), specifically iso.3.6.1.4.1.3212.100.3.2.7.4, which exposes sensitive presentation control features. An attacker can exploit this flaw remotely and without authentication, gaining access to restricted presentations and potentially hijacking the presenter role. It is crucial for users of these devices to apply the latest firmware updates and review security practices to mitigate potential risks.
