CVE-2021-23842 describes a critical vulnerability in Bosch AMC2 devices and related Access Management Systems, where the Blowfish encryption key for network communication is retrievable from firmware. This allows an attacker on the local network to decrypt, modify, and potentially reconfigure the device. With a CVSS score of 7.1 (HIGH), the vulnerability requires local network access and low privileges, but grants high confidentiality and integrity impacts. Despite its severity, there is no evidence of active exploitation, publicly available exploit code, or significant community discussion, suggesting a low current threat landscape.
