Summary

Details

In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes. This was done because the initial specification for HTTP did not specify explicitly a charset, and it was assumed to be ISO-8859-1 for historical reasons. If the password contains characters that cannot be represented in ISO-8859-1, they are silently replaced by ?. This happens with passwords that contain Chinese, Cyrillic or Greek characters, for example: αβ123 converts to ??123. An attacker can send a request with a digest Authorization header crafted with a password made of only ? characters; the server would match any password of the same length that contains non-ISO-8859-1 characters. Recent HTTP Digest RFC-7616 supports a charset parameters that defaults to UTF-8 that allows for correct encoding/decoding of passwords.
