A new security-related humble bundle, MFA bypass in Box, and a a few older style vulnerabilities: lfi2rce, allow-list bypass with an @ sign, and insecure random number seeds.
Short episode this week, stack smashing, integer overflowing and a more logical issue. Ending off with a discussion about what to do when you're stuck on CTFs.
This week is a shorter episode looking at some bad code in mermaid.js and Moodle's Shibboleth plugin, and a bit of research regarding URL parsing issues.
We are back for the first 2022 binary episode, and its all kernel. Obtaining root through an hours long exploit process on Ubuntu thanks to an invalid free, use-after-free in XNU due to bad locking, and some terrible code in Samsung S20 DSP kernel driver with multiple integer overflows.
More cases of developers make insecure assumptions and getting owned because of it. This week we've got a Flickr account takeover, escalating restricted SSRF into something more useful, and XSS to RCE in Rocket.Chat.
Hex-rays/Adobe cross-over as they move to a subscription model and we are not too happy about it, we also discuss a few interesting bugs this week from an odd optimization and a signedness bug in Chrome, to some mishandled null-bytes in runc, and a subtle object-state confusion in the Linux kernel
Log4Shell RCE spawns a lot of discussion this episode, but we also look at a W10 RCE, Google SSRF and some CSS injection in uBlock.
A few easy issues this week, but some discussion about fuzzing campaigns and measurements and bypassing modern mitigations.
Some readily understood vulnerabilities, but with some interesting impacts, from escalating self-XSS to cross-account CSRF, data exfiltration with CSS, web-cache poisoning and MFA bypassing.
