Microsoft IIS 4.0 and 5.0 Source Code Disclosure Vulnerability

Microsoft IIS 4.0 and 5.0 can be made to disclose fragments of source code which should otherwise be inaccessible. This is done by appending '+.htr' to a request for a known .asp (or .asa, .ini, etc) file. Appending this string causes the request to be handled by ISM.DLL, which then strips the +.htr string and may disclose part or all of the source of the .asp file specified in the request.

Mitigation:

Ensure that the web server is configured to deny requests for files with the .htr extension.

Microsoft IIS 4.0 and 5.0 can be made to disclose fragments of source code which should otherwise be inaccessible. This is done by appending "+.htr" to a request for a known .asp (or .asa, .ini, etc) file. Appending this string causes the request to be handled by ISM.DLL, which then strips the +.htr string and may disclose part or all of the source of the .asp file specified in the request. There has been a report that source will be displayed up to the first '<%' encountered - '<%' and '%>' are server-side script delimiters. Pages which use the <script runat=server></script> delimiters instead will display the entire source, or up to any '<%' in the page. This vulnerability is a variant of a previously discovered vulnerability, BugTraq ID 1193.
