(I expected to see it in HTTP_AUTHORIZATION, but it seems that the servers handle this !! header and do not provide it in the ENV variables). Apache provides only AUTH_TYPE (Basic|Digest) and REMOTE_USER . But IIRC there're patches around to provide the full credentials. Old Netscape Enterprise was also able to provide the full credentials (at least with a homemade plug-in), not sure for its successors iPlanet and SunONE. !! Bottom line: there are many known attacks against HttpOnly (and !! against Basic auth), that is, many known ways to elevate "standard" XSS condition to !! be able to grab session info/credentials stored in HttpOnly cookies/HTTP Basic auth. hmm, how do you use XSS to grab Basic auth? {-: Achim ------------------------------------------------------------------------- Sponsored by: Watchfire The Twelve Most Common Application-level Hack Attacks Hackers continue to add billions to the cost of doing business online despite security executives' efforts to prevent malicious attacks.
