∗∗∗ CVE-2022-42889: Keep Calm and Stop Saying "4Shell" ∗∗∗
---------------------------------------------
[...] The vulnerability has been compared to Log4Shell since it is an open-source library-level vulnerability that is likely to impact a wide variety of software applications that use the relevant object. However, initial analysis indicates that this is a bad comparison. The nature of the vulnerability means that unlike Log4Shell, it will be rare that an application uses the vulnerable component of Commons Text to process untrusted, potentially malicious input. 
In summary, much like with Spring4Shell, there are significant caveats to practical exploitability for CVE-2022-42889. With that said, we still recommend patching any relevant impacted software according to your normal, hair-not-on-fire patch cycle.

∗∗∗ FLEXlm and Citrix ADM Denial of Service Vulnerability ∗∗∗
---------------------------------------------
On June 27, 2022, Citrix released an advisory for CVE-2022-27511 and CVE-2022-27512, which affect Citrix ADM (Application Delivery Management). 
Rapid7 investigated these issues to better understand their impact, and found that the patch is not sufficient to prevent exploitation. We also determined that the worst outcome of this vulnerability is a denial of service - the licensing server can be told to shut down (even with the patch).

∗∗∗ I’m in your hypervisor, collecting your evidence ∗∗∗
---------------------------------------------
Data acquisition during incident response engagements is always a big exercise, both for us and our clients. It’s rarely smooth sailing, and we usually encounter a hiccup or two. Fox-IT’s approach to enterprise scale incident response for the past few years has been to collect small forensic artefact packages using our internal data collection utility, “acquire”, usually deployed using the clients’ preferred method of software deployment. While this method works fine in most cases, we often encounter scenarios where deploying our software is tricky or downright impossible.
