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: exploitreversing.com/2026/04… 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! I would like to thank Ilfak Guilfanov (@ilfak) and Hex-Rays SA (@HexRaysSA) for their constant and uninterrupted support, which has been vital in helping me produce this series. 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. #exploit #exploitdevelopment #windows #exploitation #vulnerability #minifilterdriver #kernel #heapoverflow

The Exploiting Reversing Series (ERS) currently features 945 pages of exploit development based on real-world targets: [+] ERS 08: exploitreversing.com/2026/03… [+] ERS 07: exploitreversing.com/2026/03… [+] ERS 06: exploitreversing.com/2026/02… [+] ERS 05: exploitreversing.com/2025/03… [+] ERS 04: exploitreversing.com/2025/02… [+] ERS 03: exploitreversing.com/2025/01… [+] ERS 02: exploitreversing.com/2024/01… [+] ERS 01: exploitreversing.com/2023/04… In the coming weeks, I will publish new articles covering exploration in areas such as Windows, Chrome, iOS/macOS, and hypervisors. Have a great day and enjoy reading. #exploit #exploitation #windows #chrome #macOS #iOS #hypervisors #vulnerabilityresearch

I am excited to release the seventh article in the Exploiting Reversing Series (ERS). Titled “Exploitation Techniques | CVE-2024-30085 (part 01)” this 119-page technical guide offers a comprehensive roadmap for vulnerability exploitation: exploitreversing.com/2026/03… Key features of this edition: [+] Dual Exploit Strategies: Two distinct exploit versions using Token Stealing and I/O Ring techniques. [+] Exploit ALPC + PreviousMode Flip + Token Stealing: elevation of privilege of a regular user to SYSTEM. [+] Exploit ALPC + Pipes + I/O Ring: elevation of privilege of a regular user to SYSTEM. [+] Solid Reliability: Two complete working and stable exploits, including an improved cleanup stage. [+] Optimized Exploit Logic: Significant refinements to the codebase and technical execution for better stability and predictability. The article guides you through the two distinct techniques for exploiting the CVE-2024-30085 Heap Buffer Overflow vulnerability. I would like to thank Ilfak Guilfanov (@ilfak on X) and Hex-Rays SA (@HexRaysSA on X) for their constant and uninterrupted support, which has helped me write these articles over time. 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! Enjoy your reading and have an excellent day.

I am pleased to announce the publication of the sixth article in the Exploiting Reversing Series (ERS). Titled "A Deep Dive Into Exploiting a Minifilter Driver (N-day)", this 251-page article provides a comprehensive look at a past vulnerability in a mini-filter driver: exploitreversing.com/2026/02… It guides readers through the entire investigation process—beginning with binary diffing and moving through reverse engineering, deep analysis and proof-of-concept stages into full exploit development. I hope this serves as a valuable resource for your research. If you enjoy the content, please feel free to share it or reach out with feedback. Have an excellent day!
