Hi,

While Active Scanning XSS DOM based rule I keep receiving the below warning, expanded the log to DEBUG but still not able to figure out the root cause and please kindly let me know what causing the problem. This warning happens only for this rule and doesn't trigger any alert/vulnerabilities. Thanks for your help and please find the attached debug ZAP log for your reference. Not using any authentication and just a simple ASP.NET web project, login and Spider & active scan for XSS DOM based rule. Let me know if you need more details.

This is just a warning and is not uncommon when using ZAP.

You can safely ignore it unless you know that it is causing other problems.

Cheers,

Simon
