CVE-2020-10634Network attack vector

Unauthenticated file disclosure via path traversal

Published May 5, 2020 · Updated Aug 4, 2024

Path traversal in the SAE IT-systems FW-50 RTU web server allows remote attackers to read files outside its intended directory. The web server resolves an attacker-controlled path from a crafted request without adequately restricting it to the served directory. No authentication or user interaction is required; exposure is limited to devices with the project web server port enabled, and the published impact is file-structure and file-content disclosure.
