How to exploit the HTTP.sys Remote Code Execution vulnerability (CVE-2022-21907)
Pattern recognition is what hundreds of security specialists in our community voted as the skill to cultivate for a rewarding infosec career. While we have some innate pattern recognition abilities, developing them is essential – and that’s a matter of practice. Working in offensive security gives you plenty of opportunities to do this, with new vulnerabilities ripe for close examination. So let’s go ahead and do just that while discovering how this CVE carries echoes from another vulnerability from a while back.

Behind the scenes – an interview with Adrian Furtuna, our founder and CEO
The constant rise in cybercrime has surely pushed companies to take their cybersecurity more seriously, and many have turned to penetration testing as a way to combat multiplying threats. Although this established practice is highly effective, there are still many necessary improvements to help scale it to the current needs of the tech ecosystem. CyberNews sat down with Adrian Furtuna, our Founder & CEO, to talk about the ins and outs of penetration testing. Here’s why Adrian believes that no matter how advanced the technology is, some aspects still need a human approach.

How to detect and exploit the Oracle WebLogic RCE (CVE-2020-14882 & CVE-2020-14883)
Pentesters love a good RCE, but, as much as we enjoy the thrill of detecting and exploiting it (ethically, of course), the tech ecosystem suffers every time one of these pops up. That’s why fast and effective recon and vulnerability assessment remain the go-to pentesting stages that help companies manage their risks so they can keep doing business and serving their customers. With your knowledge, experience, and advice, they can turn a potential hazard into a process that makes them stronger. Let’s take a closer look at the critical RCE vulnerability discovered in Oracle WebLogic Server and see how you can have a bigger positive impact in your organization and beyond it.

How to exploit the VMware vCenter RCE with Pentest-Tools.com (CVE-2021-21985)
More high-risk vulnerabilities mean more work for you. The good news? You won’t be out of work anytime soon. The bad news? You’ll probably work a lot more than you anticipate. So how do you balance the good and the not-so-great? By having a replicable process for when a high-risk CVE that leads to RCE hits your targets (the likes of CVE-2021-21985).
