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:

Key features of this edition:
[+] Dual Exploit Strategies: Two distinct exploit versions leveraging the I/O Ring mechanism.
[+] I/O Ring Edition 02:
[*] 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.
[+] I/O Ring Edition 03:
[*] 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.
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.
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 the read and have an excellent day.
