Breaking Boundaries & Demystifying Kernel SU 4 Root Access In Azure Cloud Shell
Nullcon Goa 2025 · Main Stage
This talk, titled "Colonel Conquest," presented by Wami and Abhishek, delves into the critical security implications of containerized environments, specifically within Microsoft's Azure Cloud Shell. The speakers meticulously detail two significant kernel vulnerabilities they discovered and exploited, which allowed them to bypass security boundaries and achieve full root access within an unprivileged Azure Cloud Shell session. Their research highlights the inherent challenges in securing multi-tenant cloud environments and underscores the fact that even sophisticated isolation mechanisms are not immune to well-crafted exploits.

Real kernel exploitation work on a live cloud provider target — NFTables UAF with KASLR bypass and heap leak, plus an OVS integer manipulation bug, both demonstrated against Azure Cloud Shell. The technical content is legitimate and the researchers clearly did the work themselves, not just wrapped a known CVE in a cloud narrative.
