Title: Microsoft IIS 4.0/5.0 File Permission Canonicalization Vulnerability
Severity: MODERATE
Description:
Due to an error in canonicalization affecting CGI scripts and ISAPI extensions, incorrect permissions may be set for a given file on a web server following a malformed HTTP request. This will allow a user to perform actions on CGI or ISAPI-mapped files, including reading or executing, which would normally be denied. This does not apply to files in virtual folders.The correct file is located, but is concluded to be in a location different from its actual folder. Depending on the exact nature of the malformed URL, the file may inherit the permissions of any parent folder in the file's path.
