CVE-2022-3364Public exploitNetwork attack vector

Service interruption via unbounded Fullname input

Published Sep 29, 2022 · Updated May 20, 2025

Resource exhaustion in Rdiffweb before 2.5.0a3 allows remote attackers to interrupt its web service through oversized profile input. The UserProfileForm Fullname field accepts unbounded text because it lacks a length validator, allowing extremely large values to consume server resources. A self-registered account can trigger the overload by storing a massive value and then accessing account functions; the reported consequence is service denial.
