GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

VAR-201904-0326

Vulnerability from variot - Updated: 2023-12-18 12:00

Crestron AM-100 with firmware 1.6.0.2 and AM-101 with firmware 2.7.0.2 are vulnerable to authentication bypass due to a hard-coded password in return.tgi. A remote, unauthenticated attacker can use this vulnerability to control external devices via the uart_bridge. Crestron AM-100 and AM-101 Firmware contains a vulnerability related to the use of hard-coded credentials.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Crestron Electronics AM-100 and Crestron Electronics AM-101 are both smart home gateway products of Crestron Electronics in the United States. A trust management issue vulnerability exists in Crestron AM-100 with firmware version 1.6.0.2 and AM-101 with firmware version 2.7.0.2. This vulnerability stems from the lack of an effective trust management mechanism in network systems or products. Attackers can use default passwords or hard-coded passwords, hard-coded certificates, etc. to attack affected components
