Cross-site Scripting (XSS) - Stored in orchardcms/orchardcore


Reported on

Jan 11th 2022


The application does not escape special characters before output to FE, lead to stored XSS.

Proof of Concept

  1. Go to Workflows > Create Workflow > Add Task/Event

  2. Set a title with XSS payload, e.g: aa<svg/onload=alert('hacked')>


XSS can have huge implications for a web application and its users. User accounts can be hijacked, change the html screen and insult the organization. Credentials could be stolen, sensitive data could be exfiltrated, and lastly, access to your client computers can be obtained.
