BOSCH-SA-391095-BT: Bosch Access Control products AMC2-4WCF and AMC2-2WCF have a firmware bug which may lead to misinterpretation of access card data that is sent from a Wiegand reader. This may in turn lead to granting physical access to an unauthorized person. This vulnerability affects only products with Wiegand interface, i.e., not devices with OSDP / RS485 interface.
