# Version: 9.0 rev. 171002

Description
------------
Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted web sites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user.
Vulnerability Class
--------------------
Cross-site Scripting (XSS) - https://www.owasp.org/index.php/Cross-site_Scripting_(XSS)
Proof of Concept
----------------
File Extension parameter is not properly escaped. This could lead to an XSS attack that could possibly affect administrators,users,editor.
1. Login to application and navigate to "https://example.com/sitecore/shell/Applications/Content Editor.aspx?sw_bw=1"
2. Go to media library and click on any image and edit it
3. Now in Extension input parameter inject any XSS vector like '"><svg=onload=prompt(2)>
