Root code execution via hardcoded UART credentials
Published Apr 18, 2025 · Updated Apr 18, 2025
Hardcoded credentials in Macro-video V380E6_C1 firmware 1020302 allow physically proximate attackers to obtain a root shell over UART. The root password hash is fixed in /etc/shadow on the read-only SquashFS partition, so the shared password authenticates at the UART login prompt. Exploitation requires camera disassembly and wiring to CPU-adjacent test pads, after which root access permits recordings, feeds, configuration, and software to be read, altered, deleted, or interrupted.
