Summary
The Juniper Networks CTPView server is not enforcing HTTP Strict Transport Security (HSTS). HSTS is an optional response header which allows servers to indicate that content from the requested domain will only be served over HTTPS. The lack of HSTS may leave the system vulnerable to downgrade attacks, SSL-stripping man-in-the-middle attacks, and weakens cookie-hijacking protections. This issue affects Juniper Networks CTPView: 7.3 versions prior to 7.3R7; 9.1 versions prior to 9.1R3.
Patch / fix
- Juniper Networks CTPView 7.3R7, 9.1R3
Exploit prediction
0.50% chance of exploitation in the next 30 days, higher than 43% of all scored CVEs (FIRST EPSS, 2026-11-08).
