Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) issue found in EventPrime versions up to 4.3.0.0. IDOR vulnerabilities occur when an application provides direct access to objects based on user-supplied input without proper authorization checks, allowing attackers with limited privileges to access or manipulate data they should not be able to.

Impact Analysis

Exploitation of this vulnerability can lead to unauthorized access to sensitive subscriber information, as indicated by the high confidentiality impact in the CVSS score. An attacker with low privileges could access data they are not authorized to see, potentially leading to data breaches or information disclosure.
