Zenitel vulnerabilities and threats

CVE-2025-64127 is a critical OS command injection vulnerability in the Zenitel TCIV-3+ intercom system. It arises from insufficient sanitization of user-supplied input, allowing unauthenticated remote attackers to execute arbitrary OS commands. The vulnerability has a CVSS score of 10, indicating maximum severity with full impact on confidentiality, integrity, and availability. No authentication or user interaction is required, and exploitation could lead to complete system compromise and potential lateral movement within networks. Although no known exploits are currently reported in the wild, the risk is high due to the ease of exploitation and critical impact. European organizations using Zenitel TCIV-3+ devices, especially in critical infrastructure and public safety sectors, are at significant risk. Immediate mitigation includes network segmentation, strict input validation, and monitoring for suspicious activity. Patch availability is not indicated, so compensating controls are essential until a vendor fix is released.

An OS command injection vulnerability exists due to improper input validation. The application accepts a parameter directly from user input without verifying it is a valid IP address or filtering potentially malicious characters. This could allow an unauthenticated attacker to inject arbitrary commands.

This vulnerability allows attackers to execute arbitrary commands on the underlying system. Because the web portal runs with root privileges, successful exploitation grants full control over the device, potentially compromising its availability, confidentiality, and integrity.

This vulnerability allows attackers to directly query the underlying database, potentially retrieving all data stored in the Billing Admin database, including user credentials. User passwords are stored in plaintext, significantly increasing the severity of this issue.

This vulnerability allows malicious actors to execute arbitrary commands on the underlying system of the Zenitel ICX500 and ICX510 Gateway, granting shell access. Exploitation can compromise the device’s availability, confidentiality, and integrity.

This vulnerability allows malicious actors to gain unauthorized access to the Zenitel ICX500 and ICX510 Gateway Billing Admin endpoint, enabling them to read the entire contents of the Billing Admin database.
