It is possible to get the source code of
ASP scripts by issuing the following request :

GET /null.htw?CiWebHitsFile=/default.asp%20&CiRestriction=none&CiHiliteType=Full

ASP source codes usually contain sensitive information such
as usernames and passwords.

Solution : If you need the functionality provided by
WebHits, then install the patch available at :
http://www.microsoft.com/technet/security/bulletin/ms00-006.asp
	
If you do not need this functionality, then unmap the
.htw extensions from webhits.dll using the Internet
Service Manager MMC snap-in.

Risk factor : Serious";

Il est possible d'obtenir le code source des fichiers
ASP distants en faisant la requete :

GET /null.htw?CiWebHitsFile=/default.asp%20&CiRestriction=none&CiHiliteType=Full


Les codes sources ASP contiennent souvent des informations
sensibles telles que des logins et des mots de passe.

Solution : si vous avez besoin des fonctionnalités
apportées par WebHits, alors installez le patch
disponible à :
http://www.microsoft.com/technet/security/bulletin/ms00-006.asp

Sinon, alors déliez les extensions .htw de webhits.dll au
travers du snap-in Internet Service Manager MMC.

Facteur de risque : Sérieux";
