Clarifications and Frequently Asked Questions:

What can be done to mitigate the issue?

No mitigation can be provided. An upgrade should be performed at the earliest. As per Qlik's best practices, the proxy should not be exposed to the public internet, which reduces the attack surface significantly.

What authentication methods are affected?

All authentication methods are affected.

Are environments with HTTP disabled impacted?

Environments will be affected regardless if HTTP or HTTPS are in use. These vulnerabilities affect the HTTP protocol overall, meaning even if HTTP is disabled, the environment remains vulnerable.

These attacks don’t rely on intercepting any communication, and therefore, are indifferent whether the HTTP communication is encrypted or not.

Kind regards, and thank you for choosing Qlik,
