Reflected XSS on /api/module in microweber/microweber


Reported on

Jun 21st 2022


Reflected XSS via filter bypass on /api/module using type= parameter.

Proof of Concept</script><script>alert("xss")</script>&live_edit=true&from_url=test

The value of the "type" parameter is injected into the source code of the page at line 63. Since the value of the "type" parameter is not sanitized, it is possible to close the div tag with ' </script> ' and then put javascript code.


Execute arbitrary JavaScript code with the privileges of the victim's user. This can be used for cookie stealing (account takeover), for example.
