Technical details

CVE-2026-27558 is a command injection vulnerability (CWE-78) in the /index.php/attached_devices_tab/ajax_remove_uploaded_iodd_files endpoint. A low-privileged remote attacker with valid operator credentials can inject OS commands that are executed with root privileges on the device. The vulnerability requires authentication (operator-level credentials) and network reachability to the device's web interface. Successful exploitation allows an attacker to execute arbitrary shell commands with the highest privileges, leading to complete device compromise. Firmware versions below 1.7.4 for ICE2-* and ICE3-* product lines are affected.
