CyberRota Analysis

AI-Generated

The vulnerability affects MariaDB server versions from 10.6.1 to 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, where the ACL cache can generate identical database-privilege cache keys for roles and localhost users due to an empty IP component. This flaw allows an attacker with CREATE USER privileges to create a colliding principal, potentially allowing them to exploit the cached privileges of another account. Database administrators and organizations using the affected versions should prioritize upgrading to the patched releases to mitigate the risk of privilege escalation.

Original NVD Description

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, MariaDB's ACL cache could generate the same database-privilege cache key for role and localhost user names that matched because both used an empty IP component. An attacker with CREATE USER could create the colliding principal and, when the original principal's database privileges were cached, exercise privileges assigned to the other account. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
