The most frequent vulns I found in 80+ pentests in 2022.

(thread)

1. Rate Limit Bypass

In more than half of the pentests I conducted, I found that there were no rate limits imposed on login functions or authentication mechanisms. This lack of rate limiting, combined with weak password policies, can lead to accounts being easily compromised.

2. Session Token not Invalidated upon Logout

This vuln is caused when the session token is not invalidated at user logout. If the validity of the token or the time to expiry is long, this can lead to the token being leaked, potentially resulting in a data breach or other vulns.
