Exploits Club Summary:
In their first technical blog post, Crowdfense walks through a Windows vulnerability originally made famous by the Lazarus FudModule Rootkit. The admin-to-kernel privesc results from an untrusted pointer dereference in theÂ
appid.sys driver. The post briefly touches on the vulnerability before jumping straight into exploitation. While the bug gives complete control of the instruction pointer, bypassing SMEP and kCFG requires a data-only attack. The post concludes with two different demos, each leveraging a slightly different exploit technique.
