CVE-2023-32699Public exploitNetwork attack vector

Authenticated denial of service via unbounded password hashing

Published May 30, 2023 · Updated Jan 10, 2025

Resource exhaustion in FIT2CLOUD MeterSphere 2.9.1 and earlier allows remote authenticated users to cause a service hang via login. UserLoginService.checkUserPassword passes an attacker-controlled, unbounded password to CodingUtil.md5, consuming CPU and memory before credential validation. A valid user identifier and network access to the login endpoint are sufficient; the consequence is prolonged application unavailability without reported data exposure or modification.
