Title:
firefox 40 shows a non-overrideable security error when talking to a
captive portal
Status in firefox package in Ubuntu:
Confirmed
Bug description:
When trying to connect to the airport wifi at the Portland Airport
(https://flypdxconnect.portofportland.com:8443/guestportal/gateway?sessionId=eb0a3d0a003315a2c104ce55&portal=LOC1&action=cwa),
firefox presents me with a non-overrideable security error:
Secure Connection Failed
An error occurred during a connection to
flypdxconnect.portofportland.com:8443. SSL received a weak ephemeral
Diffie-Hellman key in Server Key Exchange handshake message. (Error
code: ssl_error_weak_server_ephemeral_dh_key)
The page you are trying to view cannot be shown because the authenticity
of the received data could not be verified.
Please contact the website owners to inform them of this problem.
When the user is behind a captive portal and talking to that portal is
the only way to get Internet access, it is not acceptable to enforce
an SSL security policy where the user has no way of overriding it, no
way of fixing the server, and no reason to care about the security of
the connection to this server.
As a workaround for this issue, I ran chrome.
