An OS command injection vulnerability exists due to insufficient sanitization of user-supplied input. The application accepts parameters that are later incorporated into OS commands without adequate validation. This could allow an unauthenticated attacker to execute arbitrary commands remotely.

→CVE-2025-64127 affects Zenitel TCIV-3+ (all versions prior to 9.3.3.0): unauthenticated OS command injection via insufficiently sanitized user-supplied parameters incorporated into OS commands — monitor for unexpected command execution originating from the TCIV-3+ web interface ↗
→No authentication is required to exploit CVE-2025-64127 (PR:N, UI:N); alert on any unauthenticated HTTP requests to Zenitel TCIV-3+ management interfaces that contain shell metacharacters (e.g., ;, |, &&, $(), backticks) in parameter values ↗
→Zenitel TCIV-3+ devices should not be internet-accessible; detect and alert on any direct internet-facing exposure of these ICS devices as a precursor risk indicator ↗

·CVE-2025-64127 is one of three OS command injection CVEs (CVE-2025-64126, CVE-2025-64127, CVE-2025-64128) affecting Zenitel TCIV-3+; ensure detections cover all three injection vectors, as each involves a distinct parameter/validation failure ↗
·All versions of Zenitel TCIV-3+ prior to 9.3.3.0 are vulnerable; version fingerprinting of deployed devices is necessary to scope detection and prioritize patching ↗
·No known public exploitation has been reported at time of advisory publication; threat hunting should be proactive rather than reactive ↗
