There is (and always has been) a debate about the ethics and impact of the release of Proof-of-Concept Exploit for an identified vulnerability and Open-Source Tools related to red-teaming. The debate, well really it has devolved into an argument, is very complex, nuanced, and (in full honesty) has multiple contexts that can be applied to it. However, it has become exceptionally binary. We now have the “Pro” side and the “Anti” side… The fact that this is where the line in the sand is being drawn is, well it is almost ignorant.

Microsoft has not been having the greatest of months. First it was identified that a stollen MSA signing key was used by a Nation State to access personal and low-side US government tenants (Low-Side it the unclassified side of Government Cloud Computing). This disclosure seems to have focused all of the attention on Microsoft as more and more security researchers are diving into their cloud services. That being said, there are and have always been researchers that keep Microsoft on their Radar, just because there is always something going on there. That is the case of the latest news to hit the street about Entra ID (formerly Azure AD).

Last week Progress Software, the company behind MOVEit file transfer software, announced another SQL injection flaw had been identified and patched. This flaw is just the latest in a series of vulnerabilities that have been identified in the application after the Cl0p ransomware group was found to have exploited a different SQL injection flaw to steal data from multiple MOVEit users. The attacks started in late 2022, but the Cl0p group might have been testing different entry points as far back as June 2022.

The last couple of months have been rather busy with the identification of critical vulnerabilities. Multiple Zero-Days were found in different pieces of software including Remote Code Execution, data modification and theft, and complete compromise of other devices that require replacement rather than patching. So, with that it is not surprising that another critical flaw has been identified (and patched) in another major vendor’s devices. Fortinet has announced the release of patches for a vulnerability tracked as CVE-2023-27997.

This one goes in both the “failure of imagination” and “this is why we can’t have nice things” category. It seems that Gigabyte, for some reason, decided to embed an insecure update function into the UEFI BIOS of their motherboards, then shipped roughly 7 million of them to customers. The fatal flaw? Well, this is an update function that runs on startup. It writes a file to disk, reaches out to update servers over open HTTP then downloads any updates and installs them.

On May 19th 2023 Barracuda disclosed that there was a critical vulnerability in their Email Security Gateway appliances. This vulnerability is tracked under CVE-2023-2868 and is listed as a remote command injection vulnerability. The flaw is present in software versions 5.1.3.001 up to 9.2.0.006 for the ESG appliances only. As this was disclosed as a Zero-Day vulnerability there was an accelerated patch release schedules with the first patches made available on May 20th.

Apple’s System Integrity Protocol (SIP) has been something of a mix bag when it comes to security. It is a great feature from a raw and basic security viewpoint, but the same feature also has created challenges for the installation of third-party anti-malware and other security tools since its launch. All that aside, Microsoft, of all people, has shared details on a vulnerability that can be used by attackers to completely bypass the protections that SIP is supposed to offer.

Wait, another danger of AI article? Yes, another one. Since far too many people and companies are ok with ignoring the dangers simply for the sake of the next big shiny thing, we thought we would at least be part of the awareness of it. I might also say “I told you so” when things do start to go sideways… ok I would not be that much of a jackass, but I do think that making sure to point out issues with new technology while others seem ok with glossing them over is a good idea.

First identified in January of 2023, Samsung has put a warning about a CVSS 4.4 vulnerability (CVE-2023-21492) that Is actively being exploited in the wild. The flaw, which impacts Samsung devices that are running Android 11, 12, and 13, was first disclosed to Samsung privately on January 17th, 2023. CISA (Cybersecurity and Infrastructure Security Agency) has also issued a warning about the flaw.

Apple has rushed to release patches for CVE-2023-32409, CVE-2023-28204, and CVE-2023-32373 all of which are in the WebKit Browser engine and across all Apple platforms (IOS, IpadOS and macOS). These three flaws have also been seen to be actively exploited in the wild. This increases the significance of them and should be remediated as soon as possible by applying any available patches.
