XSS1 - Reproduced during redirect when changing protocols, added validation for the input and redirect
XSS2 - Unable to reproduce directly as stated, the submitted value was not printed back to the user anywhere on that page. I added validation anyhow.
XSS3-26 - Reproduced issues with bad values displayed on firewall_rules.php via firewall_check_for_advanced_options() in guiconfig.inc. Added encoding to that function.
XSS3/11/19 - Added DSCP value validation.
XSS4/12/20 - Added tag value validation.
XSS5/13/21 - Added tagged value validation.
XSS6/14/22 - Added statetype validation.
XSS7/15/23 - Added vlanprio validation.
XSS8/16/24 - Added vlanprioset validation.
XSS9/17/25 - Added dnpipe/pdnpipe validation.
XSS10/18/26 - Added ackqueue/defaultqueue validation.
XSS27 - Unable to reproduce as stated. New queue name field has input validation that prevents the input, old queue name is scrubbed before use when editing. Only way I could come close was to hand edit the bad value into config.xml. I added encoding to help there, but I wouldn't consider that a vulnerability as there is no way to reach that state other than directly editing the configuration.
XSS28 - Reproduced, but the actual problem was in the entry display on services_igmpproxy.php. Added encoding there, plus input validation on services_igmpproxy_edit.php
XSS29 - Could not reproduce directly, but I could see how it could be, though I couldn't make it happen with the given input or other variations. Added validation and fixed encoding of the value before use in JavaScript.
XSS30 - Reproduced, added encoding to the error message
