Summary
Zammad, an open source helpdesk and customer support system, has a stored cross-site scripting flaw in its new Vue-based ticket interface, where article content is displayed without proper output encoding. An attacker who can log in over the network can store malicious markup in a ticket article that runs in another user's browser when that user views the ticket, and the user has to take an action to trigger it.
Read the original description
Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, the new Vue-based ticket interface can render ticket article content without the expected output encoding. An authenticated user can store markup in an article that is interpreted when another user views the ticket, enabling stored cross-site scripting. The default Content Security Policy limits practical impact, and the classic REST/CoffeeScript interface is not affected. This issue is fixed in version 7.1.2.
What to do
Upgrade to a fixed version: 7.1.2.
