CVE-2023-3064Public exploitNetwork attack vector

User enumeration via pre-authentication API response

Published Jun 5, 2023 · Updated Jan 8, 2025

Information disclosure in Mobatime AMXGT-100 1.3.20 and earlier allows remote attackers to retrieve the application's user list. Before authentication, the API sends the server's existing user list, including previously stored user identifiers, in its response to the mobile client. No account or user interaction is required, and the disclosed identifiers support account enumeration and follow-on authentication-bypass or impersonation attacks.
