XPC the bug in malware patch bypass patch(es) xpc, rootpipe, malware, patches & 0days :) OUTLINE overview of.Security vulnerabilities in our customersвЂ™ web apps, mobile apps, and infrastructure endpointsвЂќ WHOIS always looking for more experts! вЂњleverages the best combination of humans and technology to discover.STICK THAT IN YOUR (ROOT)PIPE & SMOKE IT.The talk will conclude by examining AppleвЂ™s response, a second patch, that appears to squash вЂrootpipeвЂ™вЂ¦for now. So come attend (but maybe leave your MacBooks at home), as we dive into the technical details XPC and the rootpipe vulnerability, explore how malware exploited this flaw, and then fully detail the process of completely bypassing Apple's patch. Then, an astute researcher discovered that the OSX/XSLCmd malware which pre-dated the disclosure, exploited this same vulnerability as a 0day! Finally, yours truly, found a simple way to side-step Apple's patch to re-exploit the core vulnerability on a fully-patched system. First, Apple decided to leave older versions of OS X un-patched. End of story, right? Nope, instead things then got quite interesting. Dubbed вЂrootpipe,' this bug was patched in OS X 10.10.3.

The undocumented 'writeconfig' XPC service was recently uncovered by Emil Kvarnhammar, who determined its lax controls could be abused to escalate one's privileges to root. You may ask 'why would Apple add an XPC service that can create setuid files anywhere on the system - and then blindly allow any local user to leverage this service?' Honestly, I have no idea!
