VMware’s Zombie Apocalypse: Unearthing the Interstellar Villain CVE-2023-34051

Like a zombie apocalypse for your network, the VMware Authentication Bypass Flaw is back, scarier than ever. Codenamed as CVE-2023-34051, this villainous vulnerability in vRealize Log Insight could make hackers swoon like free Wi-Fi at a hackers’ convention. Let’s hope this horror movie doesn’t have another sequel!

Hot Take:

It’s like a bad re-run of a horror movie, with the zombie apocalypse attacking your network. VMware is back in the news with a fresh flaw that could give hackers root access. The code name: CVE-2023-34051. Sounds like an intergalactic villain, right? And it’s just as scary. The vulnerability in vRealize Log Insight (or as it’s now known, VMware Aria Operations for Logs) could be as popular with hackers as free Wi-Fi at a hackers’ convention.

Key Points:

  • VMware has issued a warning about PoC exploit code for an authentication bypass flaw in vRealize Log Insight, now known as VMware Aria Operations for Logs.
  • The flaw, tracked as CVE-2023-34051, allows unauthenticated attackers to execute code remotely with root permissions under certain conditions.
  • Security researchers at Horizon3 who discovered the bug, released a PoC exploit and a list of indicators of compromise (IOCs).
  • This vulnerability can be used in combination with other flaws patched by VMware in January to gain remote code execution.
  • The exploitation of this flaw requires the attacker to have a certain level of access and infrastructure setup.

Attack of the Thrift RPC Endpoints

This flaw is all about abusing IP address spoofing and various Thrift RPC endpoints. Sounds like a geeky sci-fi film, doesn't it? Well, in reality, it's a headache for network defenders. The flaw allows an attacker to write a cron job to create a reverse shell. Picture a sneaky backdoor into your network, courtesy of the attacker.

Three's a Crowd

This vulnerability is not alone. It's part of an exploit chain of critical flaws patched by VMware in January. The first is a directory traversal bug, the second is a broken access control flaw, and the third is an information disclosure bug. It's like the Three Stooges of cybersecurity, except they're not funny.

Not a Walk in the Park

While this flaw is easy to exploit, it does require the attacker to have some infrastructure setup. That means it's not a walk in the park for any script kiddie looking to cause havoc. Plus, the product is unlikely to be exposed to the internet, so the attacker would need to already have a foothold somewhere else on the network.

VMware's Old Wounds

This isn't the first time VMware has faced security issues. In June, they warned customers about another critical remote code execution vulnerability in VMware Aria Operations for Networks. It feels like a cybersecurity version of Groundhog Day. Let's hope this is the last sequel in this series.
