Podcasts Technology Day[0] [bounty] Insecure Firewalls, MyBB, and Winning with WinRAR

[bounty] Insecure Firewalls, MyBB, and Winning with WinRAR

Published: Oct. 10, 2023, noon

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.
