Ever wondered what you can still do with 25-year-old code in a modern hosting environment? PTT-2025-021 was quite the journey! Unpack this critical RCE we discovered and disclosed, which lets you bypass restricted environments like cPanel's jailshell. In part 1 of 3, we break down how an unsafe Perl "open" function became our ticket to a reverse shell - and how the exploit works.
Security teams had to cover more assets, respond to more CVEs, and explain more findings to more people than ever. And not just explain them - defend them. In front of clients. In front of auditors. In front of leadership that wants to know what actually changed since the last in-depth test.
React2Shell (CVE-2025-55182) is a CVSS 10.0, pre-auth remote code execution flaw in the React Server Components Flight protocol. This deep dive maps affected React and Next.js versions, explains the deterministic exploit chain, summarizes in-the-wild abuse, and lays out detection, mitigation, and validation steps you can apply in real environments.
Here's how we weaponized SessionReaper (CVE-2025-54236) against Magento 2, chaining ServiceInputProcessor quirks and a session proxy setter to forge customer sessions and hijack accounts. Our lab-tested PoC exposes attack surface, a possible preauth RCE, and an automated exploit - a practical walkthrough for researchers who like coffee strong and bugs reliable.
Elevate your next pentest by exploiting web cache poisoning. This deep dive uncovers the RFC nuances, common misconfigurations, and unkeyed request components that transform low-severity injections into critical, widespread compromises. Learn practical detection, exploitation (with PoCs!), and advanced mitigation techniques to weaponize your findings.
In this third installment, we stop talking and start listening. We asked seasoned offensive security professionals how they actually use machine learning in the field. Their verdict? ML works, when it’s focused. From spotting phishing entry points to flagging suspicious authentication patterns, the value is real. But it’s not magic. Used blindly, it adds noise. Used wisely, it accelerates analysts.
