What it is

The authorization middleware of the WMS MobileServer

fails to require authentication in two distinct cases. First, it

only requires an Authorization header for GET and HEAD requests; requests

using any other HTTP method are processed without an authentication check.

Second, for any HTTP method including GET and HEAD, a request carrying a

malformed or non-bearer Authorization header is passed through without

a valid token being required.

The middleware does validate a token whenever a

well-formed one is present, but in these two cases it does not

require one. A remote attacker with network access to the service can

therefore invoke API functionality without valid credentials.
