## Technical details

The /index.php/ajax/get_iodd_port_info endpoint in Pepperl+Fuchs ICE2 and ICE3 devices contains an OS command injection vulnerability (CWE-78) due to improper input validation. An authenticated attacker with low-privileged user or operator credentials can inject shell metacharacters into endpoint parameters to break out of intended command context and execute arbitrary shell commands. The vulnerability requires valid authentication (PR:L) but no user interaction, runs over the network, and allows execution of commands with root privileges, resulting in complete system compromise. Patched firmware versions 1.7.4 and later are available.
