Executive Summary

This vulnerability affects the Shopware open commerce platform versions prior to 6.6.10.18 and 6.7.10.1. An attacker can perform a timing attack to enumerate the usernames of administrator users. This means the attacker can discover valid administrator usernames by measuring the time it takes for the system to respond to certain requests.

Impact Analysis

The vulnerability allows an attacker to identify administrator usernames through timing attacks. Knowing valid administrator usernames can be a first step for further attacks, such as brute force password attempts or social engineering, potentially leading to unauthorized access to the system.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Shopware to version 6.6.10.18 or 6.7.10.1 or later, as these versions contain the fix for the administrator username enumeration timing attack.
