Root code execution via unsanitized DMACC URLs
Published Jul 14, 2022 · Updated Aug 3, 2024
OS command injection in Verizon 5G Home LVSKIHP ODU 3.33.101.0 allows remote authenticated users to execute code as root via DMACC URLs. The Settings controller inserts user-controlled DMACC URL values into shell commands without neutralizing metacharacters. Access requires Engineering portal credentials and local-network reachability; injected commands run with root privileges and can persistently alter the device.
