Remote Heap Overflow in VMware Products

Thanks to a heads-up from "yomama" in the #snort channel, I learned of this advisory from Tim Shelton:

"A vulnerability was identified in VMware Workstation (And others) vmnat.exe, which could be exploited by remote attackers to execute arbitrary commands.

This vulnerability allows the escape from a VMware Virtual Machine into userland space and compromising the host.

'Vmnat' is unable to process specially crafted 'EPRT' and 'PORT' FTP Requests."

This implies that someone who connects to a FTP server using traffic that is processed by vmnat.exe can exploit vmnat.exe.

As a VMware Workstation user, I am glad to see they have published a new version to address the vulnerability.

Zeek in Action Videos

This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti...
