222 - MTE Debuts, DNS Client Exploits, and iTLB Multihit

As memory tagging (MTE) finally comes to a consumer device, we talk about how it may impact vulnerability research and exploit development going forward. Then we get into a few vulnerabilities including a DNS response parsing bug on the Wii U, an Adobe Acrobat bug that was exploited by a North Korean APT, and a CPU bug (iTLB Multihit).

220 - Windows Kernel Bugs, Safari Integer Underflow, and CONSTIFY

Diving right into some binary exploitation issues this week. Starting wtih a look at a rare sort of curl vulnerability where a malicious server could compromise a curl user. Then we take a look at a pretty straight-forward type confusion in Windows kernel code, and an integer underflow in Safari with some questionable exploitation. Ending the episode with some thoughts on how impactful grsecurity's "constify" mitigation could be.

219 - Rapid Reset, Attacking AWS Cognito, and Confluence Bugs

We've got a mix of topics this week, started with a bit of discussion around the recent Rapid Reset denial of service attack, before diving into a few vulnerabilities. A Node "permissions" module escape due to having a fail-open condition when unexpected but supported types are passed in. Then we talk about some common AWS Cognito issues, a fun little privilege escalation in Confluence, and a log injection bug leading to RCE.

217 - Insecure Firewalls, MyBB, and Winning with WinRAR

This week we've got some fun issues, including a WinRAR processing bug that results in code execution due (imo) to a filename adjustment when extracting that isn't performed consistently. A MyBB admin-panel RCE, fairly privileged bug but I think the bug pattern could appear elsewhere and is something to watch out for, And several silly issues in a "next-gen" firewall, including source disclosures and RCEs from the login page.

216 - Busted Stack Protectors, MTE, and AI Powered Fuzzing

A binary summer-recap episode, looking at some vulnerabilities and research put out over the summer. Talking about what TPM really offers when it comes to full-disk encryption, some thoughts on AI in the fuzzing loop. Then into some cool bugs, kicking off with some ARM Memory Tagging Extension vulnerabilities, a `-fstack-protector` implementation failure and bypass, and then a look at a Android exploit that was found in-the-wild.

215 - DEF CON, HardwearIO, Broken Caching, and Dropping Headers

We are back, and talking about our summer with a lengthy discussion about our DEF CON experiences before getting into some favorite issues from the summer. Including a neat twist on a PHP security feature that might be using in your bug bounty chains. A look at classic crypto issue (unauthenticated encrypted blobs), and an easily missed caching issue.

Spot the Vuln Shirt (Solutions)

Unfortunately, we will not be directly selling these shirts, but I have another post tutorial on how to reproduce the shirt if you want to put in the bit of extra work to get one. Regex (bug-bounty style vulnerability) We've covered this vulnerability multiple times on the podcast and it was our Spot the Vuln on Episode 152 (written in Golang). The  regex in allow. It looks normal, and if you test it in the obvious ways it seems to work. api.safe.com passes, api.notsafe.com fails. Because

Spot the Vuln Shirt (DIY)

Unfortunately, we will NOT be selling the "Spot the Vuln" shirts we mentioned on the podcast. Its just due to some tax things I don't have the time to deal with right now, maybe next year. If you're willing to put in some effort though what follows is basically a tutorial on recreating the shirt within Printify so you can order it from a producer yourself. Printify is kind-of a drop-shipping system for custom clothing. You can create a product that will be fulfilled by some producer. You can
