Description

Integrics Enswitch 3.13 through 4.4 contains an authentication bypass vulnerability in /api/json/user/password/update/ that allows unauthenticated attackers to change account passwords by omitting the reset parameter. Attackers can target accounts with no pending reset, whose empty reset_key matches the defaulted empty value, to take over administrator accounts after enumerating valid usernames.

Executive Summary

This vulnerability is an authentication bypass in Integrics Enswitch versions 3.13 through 4.4. It exists in the password reset API endpoint /api/json/user/password/update/. Attackers can change account passwords without a valid reset key by omitting the reset parameter. This allows unauthenticated access to reset passwords for accounts with no pending reset, enabling account takeover after identifying valid usernames.

Detection Guidance

To detect this vulnerability, check if your Enswitch system is running versions 3.13 through 4.4. Verify if the /api/json/user/password/update/ endpoint is accessible without authentication. Test by sending a POST request to this endpoint with a valid username and no reset parameter to see if the password can be changed.

Impact Analysis

If you use Enswitch versions 3.13 through 4.4, attackers could exploit this to reset passwords of administrator accounts. This could lead to full system compromise, unauthorized access to telephony services, billing data, and sensitive user information. Attackers might make unauthorized calls, modify configurations, or steal data.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations using vulnerable Enswitch versions may face compliance violations, legal penalties, and reputational damage due to potential data breaches.

Mitigation Strategies

Immediately apply the vendor fix: for versions 3.13-4.3, update to Subversion revision 21680 or later; for version 4.4, apply Git commit c2c981578 or later. Alternatively, restrict access to the vulnerable /api/json/user/password/update/ endpoint until patched.
