Does Burp Collaborator test for "dangling markup" vulnerabilities?

Tim (MNIT) McGuire Apr 03, 2017 10:55PM UTC

This article on github ( )

outlines an attack where an attacker injects an unclosed img tag
<img src='

which then includes everything until the matching quote in a request to some-evil-site, potentially sending sensitive data.

Question, does burp collaborator find issues like this?


Dafydd Stuttard Apr 06, 2017 10:53AM UTC Support Center agent

In this situation, Burp Scanner checks for various XSS-style injection vectors, including image tags, and will report these to the user.

It doesn’t attempt to actively exploit the issue to exfiltrate data via Burp Collaborator. You could do this easily enough with the manual Burp Collaborator client and your own payloads.
