CVE-2018-17777
If the PIN of the page "/ui/cbpc/login" is the default Parental Control PIN (0000), it is possible to bypass the login form by editing the path of the cookie "sid" generated by the page.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
