Authentication Bypass in Kiteworks Core via Password Reset

Executive Summary

Kiteworks Core had a flaw in the password reset process where it did not properly validate a user-provided parameter. This allowed an unauthenticated attacker who knew the email address of a user with a locally stored password to reset that account's password without needing access to the emailed reset link. The attacker could then log in as that user, including if the account had administrative privileges.
