Title: Microsoft IIS Unicode .asp Source Code Disclosure Vulnerability
Severity: HIGH
Description:
When a user requests for a resource residing on a remote host, depending on what the file extensions is, the file will be returned and run appropriately.
A flaw exists in the handling of .asp requests. Typically when a request is made for an .asp file, IIS will identify that it is a script and run it as such. However if the host is formatted with a FAT file system and a request is made with an .asp Unicode encoded file extension, IIS may not handle the request properly and return the source code of the file.
Sensitive information in scripts (such as database usernames and passwords) may be disclosed to attackers. Vulnerabilities present in scripts may also be revealed if the source code is disclosed. This may facilitate further attacks against the server.
