1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-59814 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is of critical severity. The high score is likely due to the potential for unauthorized access to sensitive data, which can lead to significant financial and operational impacts. The 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. This level of access can result in the exposure of confidential information, including billing records, customer data, and financial transactions.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Malicious actors can exploit this vulnerability over the network, potentially targeting the Billing Admin endpoint directly.
• Phishing and Social Engineering: Attackers may use phishing techniques to gain initial access to the network and then exploit this vulnerability to escalate privileges.
• Insider Threats: Internal actors with limited access could exploit this vulnerability to gain unauthorized access to the Billing Admin database.

Exploitation Methods:

• SQL Injection: If the endpoint is vulnerable to SQL injection, attackers could craft malicious SQL queries to extract data.
• Authentication Bypass: Attackers may exploit weaknesses in the authentication mechanism to bypass security controls and access the database.
• Credential Stuffing: Using previously compromised credentials, attackers could gain access to the Billing Admin endpoint.

3. Affected Systems and Software Versions

Affected Systems:

• Zenitel ICX500 Gateway
• Zenitel ICX510 Gateway

Software Versions:
