CVE-2022-0968

Service interruption via unbounded user profile fields

Published Mar 15, 2022 · Updated Aug 2, 2024

Denial of service in Microweber before 1.2.12 allows local users to interrupt service through oversized user-profile fields. UserCreateRequest and UserUpdateRequest accepted unbounded first_name, last_name, phone, username, and email values; the patch caps each at 500 characters. A user creation or update workflow must be reachable, and published sources do not identify whether interruption takes the form of a hang or crash.
