Security researchers observed hackers exploiting a vulnerability only 22 minutes after releasing proof of concept (PoC). It is the case of CVE-2024-27198, an authentication bypass flaw in JetBrains TeamCity. The CVE has a 9.8 CVSS score, which is critical.
Hackers can use this vulnerability to execute arbitrary code and take complete control of the compromised devices. All they need to do to exploit it is sending one HTTP request to the targeted system.
If they succeed, the flaw enables them to launch the attack remotely and unauthenticated, said the researchers.
Patch fast and use a layered defense strategy
CVE-2024-27198 was first published in April 2024. By then, security journalists warned that the flaw was already exploited, only one day after being published.
A recent report showed evidence that in fact, hackers were able to exploit CVE-2024-27198 only 22 minutes after publishing. In that case, they deployed a PoC-based exploit.
This means that once the proof of concept was released, System Administrators had less than half an hour to apply patches. Automated patch management is a crucial tool for winning the patching race. Prioritizing vulnerabilities and timely applying patches are some of the greatest challenges System Administrators face.
But 22 minutes is still too fast.
This is why cybersecurity expert Robertino Matausch advises not only using an AI-powered threat detection solution, but also enforcing a layered defense strategy to protect infrastructure.
Layered security is always important. Somehow, the zero-day must get in your environment. It is not teleported.
It’s a bit like in warfare. The hackers need access and ways to deploy – if you close those access paths the best you can – through a layered security approach – you are increasing your chances of not being hit.
Imagine this: what are you doing when a storm rises? You close all the windows and doors and strengthen/cover them. Fast patching and layered security are exactly that. One strong, effective security tool is good, but teaming them up is much better.
Speed-up and enhance security with Heimdal’s XDR platform
Integrating tools improves visibility and speeds-up detection and incident response. Just like in human teams, effective communication and skills matching bring better results.
Heimdal’s XDR offers a clear, unified view of your IT environment. It uses advanced AI and Machine learning technology to detect threats faster and more accurately than traditional security solutions. Its quick automated responses reduce the time needed to identify and address security incidents.
