Description

Microsoft IIS contains a flaw that allows a remote attacker to view the source of .asp files. The issue is due to IIS mapping all .htw files to be handled by Webhits.dll. By appending a space (%20) to the end of a filename or calling CiWebHitsFile as a variable, setting the "CiHiliteType" variable to "Full", and setting the "CiRestriction" variable to "None", the server will return the source of an .asp file.
