Discussion this week around Chrome's Sanitizer API, and bypassing firewalls with webhooks and 0days (ModSecurity bypass), and a pre-auth BitBucket RCE.
We are back at it, covering some write-ups and exploits we found interesting this summer. From browse-powered desyncs, to account take overs
Last bounty episode before our summer vacation, and we are ending off with some cool issues. XML Stanza smuggling in Zoom for a MitM attack, an odd auth bypass, a Gitlab Stored XSS and gadget based CSP bypass, and an interesting technique to leverage a path traversal/desync against NGINX Plus
Kicking off the week with some discussion about DOJ's policy change before getting into some vulnerabilities: "powerdir" a macOS TCC bypass, an integer overflow on the web, and another attack against HelloSign and their Google Drive integration
A lot of cool little bugs this week with some solid impact, Facebook and Priceline account takeovers, F5 iControl Authentication Bypass, and a couple other logic bugs.
Some interesting vulnerabilities this week from a Cloudflare Pages container escape chain, to hacking a bank's web application with some neat tricks to get abuse a file-write in a hardened envrionment, and even another dumb smart-contract bug.
Some straight forward bugs this week with some interesting discussion around cryptographic protocols (VMWare Workspace), XSS in the Web3 world, and whether container escapes into a low-privileged VM matter. Along with a couple just note-worthy test-cases to keep in mind while bug hunting.
An intresting mix of issues from crypto (Psychic Signatures), to a bad vulnerability patching service (patching log4shell), and bad logic leading to authentication bypassing and leaking sensitive keys.
Short episode this week, looking at some relatively simple vulnerabilities ranging XSS, to leaking internal service credentials in AWS Relational Database Service by disabling validiation.
Quick bounty episode this week with some request smuggling, abusing a SSRF for client-sided impact, a weird oauth flow, and a desktop VPN client LPE.
