Technical details

This is a command injection vulnerability (CWE-78) in the /api/datastorage/data endpoint accessible via PUT request. The vulnerability requires high-privilege credentials (admin authentication), but allows an authenticated attacker to inject OS commands that execute with root privileges. The root cause is insufficient sanitization of user-supplied input in the datastorage API handler. An attacker can leverage this to achieve remote code execution with the highest system privileges, enabling complete device compromise. Fixes are available in firmware versions 1.7.4 and later for both ICE2-* and ICE3-* product lines.
