What is CVE-2022-29701?

The 'forgot password' functionality in Zammad v5.1.0 is compromised by inadequate rate limiting measures. This oversight permits attackers to bombard a legitimate user's account with a significant volume of reset requests, potentially leading to a Denial of Service (DoS) situation. As a result, the target user may face an overwhelming flood of email notifications, disrupting their access and the overall functionality of the system. This vulnerability emphasizes the importance of implementing robust rate limiting to safeguard against abuse.
