CVE-2023-39854Public exploitNetwork attack vector

Authenticated file disclosure and SSRF via URL fetch

Published Oct 9, 2023 · Updated Sep 19, 2024

SSRF and local file inclusion in ATX UCrypt 3.5 and earlier allow remote authenticated users to read system files or reach remote hosts. The /hydra/view/get_cc_url endpoint passes its url parameter to server-side retrieval without restricting file or network destinations. Any valid account, including an unchanged default admin, master, or user credential, exposes local files and server-reachable resources.
