Vulnerability Details

The following table shares brief descriptions of the vulnerabilities addressed in this document.

Vulnerability ID Vulnerability Description
84502

The remote HTTPS server is not enforcing HTTP Strict Transport Security (HSTS). The lack of HSTS allows downgrade attacks, SSL-stripping man-in-the-middle attacks, and weakens cookie-hijacking protections.

When initially connecting to ACOS Web-GUI via HTTPS, a redirect response to the root page (GET / HTTP/1.1) is missing HTTP Strict Transport Security (HSTS) from the server.
