Microsoft IIS is a web server for Windows platforms.
Microsoft IIS 4.0 and 5.0 allow path validation checks to be bypassed by URL-encoding invalid characters twice. Thus, a backslash is first represented as %5c, and then %255c. This allows remote attackers to access any executable file on the system using a directory traversal attack from the /scripts virtual directory, leading to command execution.
Install the patch referenced in Microsoft Security Bulletin 01-026.
