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 03)” I provide a 106-page deep dive and a comprehensive roadmap for vulnerability exploitation:

https://exploitreversing.com/wp-content/uploads/2026/04/exploit_reversing_09.pdf

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 WNF OOB + PreviousMode flip + _EPROCESS.Protection strip + MiniDumpWriteDump function – elevation of regular user to SYSTEM AND full LSASS credential extraction (NT hashes, Kerberos tickets, DPAPI keys).
[+] 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 on X) and Hex-Rays SA (@HexRaysSA on X) 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.

Exploiting Reversing (ER) series: article 08 | Exploitation Techniques: CVE-2024-30085 (part 02)

Today I am releasing the eighth article in the Exploiting Reversing Series (ERS). In “Exploitation Techniques | CVE-2024-30085 (Part 02)” I provide a 91-page deep dive and a comprehensive roadmap for vulnerability exploitation:

https://exploitreversing.com/wp-content/uploads/2026/03/exploit_reversing_08.pdf

Key features of this edition:

[+] Dual Exploit Strategies: Two distinct exploit versions leveraging the I/O Ring technique.
[+] 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.

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.

Exploiting Reversing (ER) series: article 06 | A Deep Dive Into Exploiting a Minifilter Driver (N-day)

I am excited to release the extended version of the sixth article in the Exploiting Reversing Series (ERS). Titled “A Deep Dive Into Exploiting a Minifilter Driver (N-day)” this 296-page deep dive (rev. C1) offers a comprehensive roadmap for vulnerability exploitation:

https://exploitreversing.com/wp-content/uploads/2026/03/exploit_reversing_06_extended_rev_c.pdf

Key updates in this extended edition:

[+] Dual Exploit Strategies: Two distinct exploit versions.
[+] Exploit ALPC Write Primitive Edition: elevation of privilege of a regular user to SYSTEM.
[+] Exploit Parent Process ID Spoofing Edition: elevation of privilege of an administrator to SYSTEM.
[+] Solid Reliability: A completely stable and working ALPC write primitive.
[+] Optimized Exploit Logic: Significant refinements to the codebase and technical execution for better stability and predictability.

For those who have read the original release, whose exploit was working, my strong recommendation is that you adopt this extended edition as definitive.

This revision C.1 features a refined ALPC exploit with a new stage and an extended cleaner stage, ensuring a stable exit and preventing system crashes.

The article guides you through the entire lifecycle of an exploit: from initial reverse engineering and vulnerability analysis to multiple PoC developments and full exploitation.

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.
