The lack of HSTS may leave the system vulnerable to downgrade attacks, SSL-stripping man-in-the-middle attacks, and weakens cookie-hijacking protections.

  • 7.3 versions prior to 7.3R7;
  • 9.1 versions prior to 9.1R3.


Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
