Executive Summary

CVE-2025-70363 is an access control vulnerability in the REST API of Ibexa eZ Platform and Ciril Platform version 2.x.

This flaw allows unauthenticated attackers to enumerate object IDs and thereby gain unauthorized access to sensitive data.

The issue arises due to incorrect access control mechanisms within the API, enabling attackers to bypass authentication and retrieve protected information.

Impact Analysis

This vulnerability can allow unauthenticated attackers to access sensitive data without proper authorization.

By enumerating object IDs through the REST API, attackers can retrieve protected information that should normally be restricted.

Such unauthorized data access can lead to data breaches, loss of confidentiality, and potential misuse of sensitive information.

Mitigation Strategies

Immediate mitigation steps should focus on restricting unauthenticated access to the REST API endpoints that expose sensitive data.

Ensure proper access control mechanisms are enforced on the API to prevent enumeration of object IDs by unauthenticated users.

If possible, apply any available patches or updates from the vendor that address this access control issue.

As a temporary measure, consider restricting network access to the API to trusted users or IP addresses until a permanent fix is applied.
