Requesting a URL with '/./' prepended to it
makes the remote Allaire Server display the content of 
a remote directory, instead of its index.html file.

An attacker may use this flaw to download 'hidden' files on 
your server.

Solution : upgrade to JRun 3.0sp2
Risk factor : Low/Medium";

 desc["francais"] = "
Demander une URL avec un '/./' au début force un serveur
Allaire à afficher le contenu du répertoire demandé, au lieu
du traditionel index.html.

Un pirate peut utiliser ce problème pour télécharger les fichiers
'cachés' de votre serveur.

Solution : mettez à jour JRun 3.0sp2
Facteur de risque : Faible/Moyen";
