CVE-2024-39776Network attack vector

Unauthenticated sensitive-file disclosure via web root

Published Aug 22, 2024 · Updated Aug 22, 2024

Sensitive-data exposure in Avtec Outpost products before 5.0.0 allows remote attackers to read files through an unauthenticated web interface. The products store sensitive files under the web document root without access controls, making them directly retrievable over HTTP. Port 80 access is the stated gate; no exposed filename is public, and the documented consequence is disclosure without modification or interruption.
