The ELCA Star Transmitter Remote Control firmware 1.25 for STAR150, BP1000, STAR300, STAR2000, STAR1000, STAR500, and possibly other models, contains an information disclosure vulnerability allowing unauthenticated attackers to retrieve admin credentials and system settings via an unprotected /setup.xml endpoint. The admin password is stored in plaintext under the <p05> XML tag, potentially leading to remote compromise of the transmitter system.
