Exploiting Reversing (ER) series: article 09 | Exploitation Techniques: CVE-2024-30085 (part 03)

Today I am releasing the nineth article in the Exploiting Reversing Series (ERS). In “Exploitation Techniques | CVE-2024-30085 (Part 09)” I provide a 106-page deep dive and a comprehensive roadmap for vulnerability exploitation:

https://exploitreversing.com/2026/04/28/exploiting-reversing-er-series-article-09/

Key features of this edition:

[+] Dual Exploit Strategies: Two distinct exploit editions built on the cldflt.sys heap overflow.
[+] PreviousMode Edition: Exploit cldflt.sys via WNF OOB + Pipe Attributes + ALPC + _KTHREAD.PreviousMode flip: elevation of privilege of a regular user to SYSTEM.
[+] PPL Bypass Edition: Exploit cldflt.sys via WNF OOB + PreviousMode flip + _EPROCESS.Protection strip + MiniDumpWriteDump: elevation of regular user to SYSTEM.
[+] Solid Reliability: Two complete, stable exploits, including a multi-step cleanup phase that restores the corrupted pipe attribute Flink and _KTHREAD.PreviousMode before process exit, preventing crash on cleanup.

This article guides you through two additional techniques for exploiting the CVE-2024-30085 Heap Buffer Overflow. While demonstrated here, these methods can be adapted as exploitation techniques for many other kernel targets.

I hope this serves as a definitive resource for your research. If you find it helpful, please feel free to share it or reach out with your feedback!

The following articles will continue the miniseries about iOS and Chrome, which are my areas of research.

Enjoy the reading and have an excellent day.

AI Models Accelerate Vulnerability Research, Raising Cybersecurity Risks

Commercial AI models are rapidly advancing vulnerability research and exploit development, cutting the time from discovery to exploitation and significantly raising the stakes for cybersecurity. This emerging trend poses new and heightened risks for the industry.

AI Models Accelerate Vulnerability Discovery, Pressing Defenders to Adapt

The double-edged sword of AI: while it's being used to help developers, it's also become a powerful tool for attackers to rapidly discover and exploit software flaws, forcing defenders to scramble to keep up. As AI-powered vulnerability discovery accelerates, the pressure is on for defenders to adapt and…

"Our internal evaluations showed that Opus 4.6 generally had a near-0% success rate at autonomous #ExploitDevelopment But #MythosPreview is in a different league.

For example, Opus 4.6 turned the vulnerabilities it had found in Mozilla’s Firefox 147 JavaScript engine—all patched in Firefox 148—into JavaScript shell exploits only two times out of several hundred attempts. We re-ran this experiment as a benchmark for Mythos Preview, which developed working #exploits 181 times, and achieved register control on 29 more."

Last weekend I attended FlagWars 2026, an in-person CTF organized by Laokoon, IBM and CGI. It has been some time since my last Jeopardy CTF, so getting back into it was a great time. Beyond the competition itself, you always meet a ton of cool new (and familiar!) people at these events.

To recap one of the challenges, I wrote up my full solve for "Lightsaber Constructor", a pwn challenge where a Use-After-Free bug let me chain tcache poisoning and a GOT overwrite for a shell. Check it out and let me know what you think!

Key features of this edition:

[+] Dual Exploit Strategies: Two distinct exploit versions leveraging the I/O Ring mechanism.
[+] Exploit ALPC + WNF OOB + Pipe Attributes + I/O Ring: elevation of privilege of a regular user to SYSTEM.
[+] Replaced ALPC one-shot write with Pipe Attribute spray for I/O Ring RegBuffers corruption: more reliable adjacency control.
[+] Exploit WNF OOB + I/O Ring Read/Write: elevation of privilege of a regular user to SYSTEM.
[+] Pure I/O Ring primitive: eliminated ALPC dependency entirely. WNF overflow directly corrupts I/O Ring RegBuffers for arbitrary kernel read/write.
[+] Solid Reliability: Two complete, stable exploits, including an improved cleanup stage.

I just popped a SYSTEM shell on a Windows 7 machine using my own penetration testing framework written entirely in Rust.

Amatsumara is a full exploitation framework including dynamic module loading via C FFI, interactive console, session management, 154 exploit modules, all built in Rust. Tonight I finished implementing EternalBlue (MS17-010) from scratch. Heap grooming, the SrvOs2FeaListToNt integer overflow, kernel shellcode, SrvNet buffer corruption, OS detection to automatically route between Win7 and Win8 exploit paths.

Now I have to try to find a way to sleep and not keep messing around in excitement.
