CVE-2024-7743Public exploitNetwork attack vector

Unauthenticated SSRF via unfiltered download URL

Published Aug 13, 2024 · Updated Aug 16, 2024

SSRF in the downloadUrl API endpoint in Yifang Software LTCMS 1.0.20 allows remote attackers to initiate server-side requests. The app/utils/base/helper/Ltcms_download.php handler passes the attacker-controlled file value to curl_exec without scheme or destination filtering. No authentication or user interaction is required, and the blind requests can reach internal network services or local-resource protocols.
