CVE-2021-46417Public exploitNetwork attack vector

Unauthenticated file disclosure via download path traversal

Published Apr 7, 2022 · Updated Aug 4, 2024

Path traversal in Franklin Fueling Systems Colibri Controller Module 1.8.19.8580 allows remote attackers to read internal files. The tsaupload.cgi download handler uses the file_name query value as a filesystem path without restricting parent-directory sequences. A crafted unauthenticated HTTP GET request retrieves files readable with root privileges, including /etc/passwd, without changing data or interrupting service.
