We've got a cloud focused episode this week, starting with a logging bypass in AWS CloudTrail, a SSH Key injection, and cross-tenant data access in Azure Cognitive Search.
An Apple-focused episode this week, with a trivial iPod Nano BootRom exploit, and a WebKit Use-after-free. We also have a really cool XNU Virutal Memory bug, strictly a race condition and a logic differential between two alternate paths resulting in bypassing copy-on-write protection. We also handle a few questions from chat, how much reverse engineering is necessary for vuln research, how much programming knowledge is required, and a bit about AI's applicability to reverse engineering.
This week kicks off with another look at client-side path traversal attacks, this time with some more case-studies. Then we get into some mobile issues, one a cool desync between DER processors resulting in an iOS privilege escalation. The other a Bundle processing issue in Android that provides an almost use-after-free like primitive but in Java.
Just a few issues this week, but some solid exploitation. A Kernel UAF, IoT, and a bhyve escape.
First episode of the new year, and we've got some cool stuff. Several authentication issues and "class pollution" in Python.
In this episode, we discuss the discovery of a type confusion in Internet Explorer's JScript. We also explore a fun exploit strategy for a low-level memory management bug in the Linux kernel and delve into several issues in Huawei's Secure Monitor that enable code execution in the secure world.
Is Pwn2Own worth it for bug bounty hunters? A handful of trivial command injections, and some awesome WAF bypasses.
Will AI be your next vuln research assistant? ... Maybe? We also talk about a stack-based overflow in `ping` and a Huawei hypervisor vuln.
A variety of issues this week, DOM Clobbering, argument injection, a filesystem race condition, cross-site scripting, and a normalization-based auth bypass.
The end of kASLR bypasses? Probably just click-bait, but the patch gap is real and we discuss that a bit before getting into a couple AI-based corruptions.
