CVE-2024-2323 · Severity: medium · CVSS 4.8 · Published 2026-10-20

WSO2's user identity management service fails to properly restrict password change attempts when password history validation is enabled, allowing attackers to guess user passwords through brute force. An attacker exploiting this can impersonate legitimate users and gain unauthorized account access, with success depending on password complexity.

## Technical details

The RemoteUserStoreManagerService insufficiently validates password change attempts during password history validation, allowing repeated brute force guesses without adequate rate limiting or lockout mechanisms. This is an authentication bypass or brute force attack vector requiring network access to the service. An attacker can discover user credentials and achieve account takeover.
