EVA-Web <=2.1.2 vuln.

###############################################
Vuln. discovered by : r0t
Date: 27 may 2006
vendor:http://spip-edu.edres74.net/
affected versions:2.1.2 and prior
###############################################

Vuln. Description:

EVA-Web contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "debut_image" parameter in "article-album.php3" and "date" parameter in "rubrique.php3" and "perso","aide" parameters isn't properly sanitised before being returned to the user.
This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

examples:

/article-album.php3?id_article=39&debut_image=[XSS]
/rubrique.php3?id_rubrique=29&date=[XSS]
/?perso=[XSS]
/?aide=[XSS]


+
/?perso=full path
/?aide=full path


###############################################
Solution:
Edit the source code to ensure that input is properly sanitised.
