Description:
Some weaknesses have been reported in Microsoft Outlook Web Access (OWA), which potentially can be exploited by malicious people to conduct phishing attacks.
1) A weakness is caused due to a design error in the way OWA uses an unverified user supplied argument to redirect a user after successful authentication. This can e.g. be exploited by tricking a user into following a link from a HTML document to the trusted login page with a malicious "url" parameter. After successful authentication, the user will be redirected to the untrusted (fake) site.
2) A weakness is caused due to the "redir.asp" script allowing to redirect users to a site specified within the "URL" parameter. This can be exploited to e.g. redirect users to an (untrusted) fake site.
