[German]Small note to the blog readership. The developer of the browser add-in "I don't care about cookies" has just announced that he has sold his product to AVAST. I don't begrudge Daniel Kladnik this sale, but I have some thoughts of my own in the back of my mind about whether the extension is really in good hands with AVAST. Here is some information about this topic.
[German]There is a serious vulnerability (backdoor) in the firmware of power delivery units from the US manufacturer Networx. In older versions (prior to version 2.0.2a ), the firmware does not perform authentication, i.e. it is possible to switch off the power delivery unit (PDU) via the network. This is deadly if these units are used for power supply in data centers and are accessible via internet. After a reader's tip, I contacted the manufacturer and GErman CERT Alliance about this. After much back and forth, there is now a working update. Below I disclose the details. Operators should urgently isolate the PDUs and install the firmware update promptly.
[German]Sort September 2022 patchday recap. It looks like the cumulative (security) update KB5017308 released on September 13, 2022 for Windows 10 comes with collateral damage.

As of September 13, 2022, Microsoft has released a few more updates for the .NET Framework. Bolko pointed it out here (thanks for that).

[German]The vulnerability CVE-2022-35742 in Outlook was closed by Microsoft in August 2022 by means of security updates (see Patchday: Microsoft Office Updates (August 9, 2022)). However, Microsoft only provides updates for the MSI versions of Outlook 2013 and 2016. ACROS Security has now released a micropatch that closes the vulnerability in Microsoft Outlook 2010.
[German]A recent lawsuit filed by the Arizona Attorney General against technology company Google shows that the company continues to track users who have declined location tracking anyway. Thus, IP addresses of Google users served to obtain accurate location information and then used for Google services. On October 24, 2022, Arizona's lawsuit against Google is scheduled to be heard – and I think the EU will be watching closely as well, since Google is in the sights of EU antitrust watchdogs for various competition complaints and there are also GDPR complaints from consumer protection organizations.
[German]On September 13, 2022 (second Tuesday of the month, Microsoft Patchday), Microsoft released several security-related updates for still-supported Microsoft Office versions and other products. The updates are available for the installable MSI version of Microsoft Office (the click-to-run packages obtain the updates through other channels). Office 2019 does not appear in the list because it is distributed via click-to-run packages and receives security updates via the Office Update feature. Below is an overview of the available updates.
