CVE-2022-3273Public exploitNetwork attack vector

Account takeover via unthrottled password-change attempts

Published Oct 6, 2022 · Updated Aug 3, 2024

Missing attempt throttling in Rdiffweb before 2.5.0a4 allows remote authenticated users to brute-force a current password. The password-change handler in UserProfileForm repeatedly validates attacker-supplied current-password values without tracking failures or ending the session. Any signed-in user can make unlimited guesses against that account until the password is recovered, enabling persistent account takeover.
