CVE-2023-42797Network attack vector

Root command execution via malformed IPv4 conversion

Published Jan 9, 2024 · Updated Jun 3, 2025

Command injection in SICAM A8000 CP-8031 and CP-8050 before CPCI85 V05.20 allows remote authenticated users to execute commands as root. The network configuration service can leave a variable uninitialized while converting crafted IPv4 addresses, then uses it in later validation. An attacker must have rights to modify network configuration and trigger device startup; injected commands then run with root privileges.
