This issue only impacts Qlik Sense Enterprise for Windows. Other Qlik products including Qlik Cloud and QlikView are NOT impacted.
Qlik provides patches for major releases until the next Initial or Service Release is generally available. See Release Management Policy for Qlik Software. Notwithstanding, additional patches for earlier releases may be made available at Qlik’s discretion.
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.
I have checked in with our subject matter experts, and my original message is still accurate. Unbundling PostgreSQL using QPI allows for direct control of your PostgreSQL instance and facilitates maintenance without a dependency on Qlik Sense. Further Database upgrades can then be performed independently and in accordance with your corporate security policy when needed, as long as you remain within the supported PostgreSQL versions. See How To Upgrade Standalone PostgreSQL. If you are looking for information on how to achieve the same without QPI, see How to configure Qlik Sense to use a dedicated PostgreSQL database .
This PostgreSQL CVE is not related to the CVEs discussed in this blog post. For further questions regarding it please either post a new thread in our Deployment and Management forum or contact Qlik Support.
This issue only impacts Qlik Sense Enterprise for Windows. Other Qlik products, including Qlik Cloud and QlikView (or NPrinting in your specific question), are NOT impacted.
Its helpful. We have upgraded our version according to fix you have mentioned above.
One thing want to ask after upgrade how can we validate if the fix is applied or how can we test the environment to make sure the applied fix is the permanent solution for such issue.
Please help me understand the timeline correctly. This page was posted 20th September, right? Was the issue, that was later assigned CVE-2023-48365, already known at that time? Or put another way... Was the patch August 2023 Patch 2 described as a security patch from the beginning?
This alert (from the 20th of September) is about CVE-2023-48365 specifically. The blog post was, however, originally posted without a CVE number, as Qlik did not receive a CVE number until later. You can, however, find Qlik's internal issue ID in the Security Bulletin as well as in the release notes: QB-21683.
The August 2023 Patch 2 was not merely a security patch. It included a wider range of fixes.
I hope this answers the question. Should I have misunderstood something, please let me know.
