Vulnerability from github – Published: 2022-09-30 00:00 – Updated: 2024-10-25 21:46

Summary

rdiffweb's unlimited length Fullname field can lead to DoS

Details

rdiffweb prior to 2.5.0a3 does not validate email length, allowing users to insert an email longer than 255 characters. If a user signs up with an email with a length of 1 million or more characters and logs in, withdraws, or changes their email, the server may cause denial of service due to overload.

Severity ?
