How the CVE Works:
CVE-2025-25984 exploits improper access control in the UART (Universal Asynchronous Receiver-Transmitter) debugging interface of the Macro-video V380E6_C1 IP camera (firmware version 1020302). A physically proximate attacker can connect to exposed UART pins, bypass authentication, and gain a root shell. This allows arbitrary code execution by sending crafted commands via serial communication, leading to full device compromise. The flaw stems from missing secure boot and insufficient debug interface restrictions.
DailyCVE Form:
Platform: Macro-video V380E6_C1
Version: 1020302
Vulnerability: UART code execution
Severity: Critical
Date: 06/25/2025
Prediction: Patch by Q3 2025
What Undercode Say:
Analytics:
– `uart-ls /dev/ttyUSB0`
– `minicom -b 115200 -D /dev/ttyAMA0`
– `echo “payload” > /proc/debug`
Exploit:
1. Physically access UART pins.
2. Send malformed AT commands.
3. Escalate to root via buffer overflow.
Protection:
- Disable UART in firmware.
- Implement secure boot.
- Enforce serial auth.
Impact:
- Full device takeover.
- Surveillance compromise.
- Network pivoting.
