CVE-2021-46107Public exploitNetwork attack vector

Unauthenticated file disclosure via download URI dereference

Published Mar 17, 2022 · Updated Aug 4, 2024

SSRF in Ligeo Archives Ligeo Basics 02_01-2022 allows remote attackers to read server-accessible documents through its download feature. The /archive/download route accepts an attacker-controlled file URI and dereferences it server-side; the published proof of concept retrieves file:///etc/passwd. No authentication or user interaction is required; exposure is bounded to resources the application server can retrieve, with no reported write or service-interruption capability.
