The Art of Responding to Advisories, Responsible Patching, and Transparency with Users

Recently, I communicated 3 serious security vulnerabilities that affected major a Java-based CMS that powers.

I sent a message via e-mail, and they quickly released a “hot fix” that was merely hiding the vulnerable files behind their authentication system.

The reason this is not an effective way to protect your digital applications is because an authenticated user is the highest-profile target in a digital attack. If someone were to exploit these vulnerabilities, it would most likely be through a spear-phishing scheme.

What was most surprising was that none of these 3 security vulnerabilities were addressed in their change log, and the most recent post that stated “vulnerability” was a full major version ago.

So, what does a security researcher do at this point?

Let’s try getting them on the phone and scheduling a time to work through proper remediation.

dotCMS v5.1.1 Open Redirect Vulnerability

dotCMS v5.1.1 suffers from an Open Redirect Vulnerability, in addition to many other vulnerabilities that I am still verifying.

The following URL is a proof-of-concept that requires a user to be logged in. Simply login to the demo before visiting the supplied POC.

Logging into the demo requires you to go to https://demo.dotcms.com/dotAdmin and log in with the demo credentials (username: admin@dotcms.com password: admin).

dotCMS v5.1.1 HTML Injection & XSS Vulnerability

dotCMS v5.1.1 suffers from an HTML injection and XSS vulnerability, in addition to many other vulnerabilities that I am still verifying.

Here’s a screenshot of HTML injection:

To reproduce this vulnerability, simply go to https://dotcms.com/dotAdmin/ and login with their demo credentials (username: admin@dotcms.com password: admin) and then visit the following URL:

There are more unconfirmed vulnerabilities in dotCMS.
