Summary
Microsoft IIS is prone to an authentication-bypass vulnerability and a source-code disclosure vulnerability because it fails to properly sanitize user-supplied input.
An attacker can exploit these vulnerabilities to gain unauthorized access to password-protected resources and view the source code of files in the context of the server process
this may aid in
further attacks.
Microsoft IIS 6.0 and 7.5 are vulnerable
other versions may also
be affected.
