Class Stored Cross-Site Scripting Remote Yes Credit Michael Savage of Dionach (vulns@dionach.com) Vulnerable MojoPortal 2.3.9.7 MojoPortal is prone to a stored cross-site scripting vulnerability because it does not escape the titles of forum threads when inserting into the page title element. An attacker may leverage this issue to run JavaScript in the context of another user's browser. MojoPortal 2.3.9.7 is known to be vulnerable. Other versions may also be vulnerable. To exploit this issue, an attacker must create a crafted post, for example: POST /Forums/EditPost.aspx [txtSubject=+</title><script>alert("XSS!")</script>] The vendor has released an updated version (2.3.9.8) which is believed to resolve this issue.
