On the second day of Pwn2Own Vancouver 2023, the organization awarded $475,000 for 10 unique zero-day vulnerabilities, bringing the total awarded to $850,000!
The bug hunters demonstrated zero-day attacks against the Oracle VirtualBox virtualization platform, Microsoft Teams, Tesla Model 3, and the Ubuntu Desktop OS.
The day began with the success/collision achieved by Thomas Imbert (@masthoon) and Thomas Bouzerar (@MajorTomSec) from Synacktiv (@Synacktiv) demonstrating a 3-bug chain against Oracle VirtualBox with a Host EoP. The success was classified as a “collision” because one of the bugs exploited in the attack was previously known. The due earned $80,000 and 8 Master of Pwn points.
The researchers @hoangnx99, @rskvp93, and @_q5ca from Team Viettel (@vcslab) chained 2 vulnerabilities to hack Microsoft Teams. They earn $75,000 and 8 Master of Pwn points.
Of course, the most interesting attack was conducted by David Berard (@_p0ly_) and Vincent Dehors (@vdehors) from Synacktiv (@Synacktiv) who exploited a heap overflow and an OOB write to hack Tesla – Infotainment Unconfined Root. They qualify for a Tier 2 award, earning $250,000 and 25 Master of Pwn points. The team also won the Tesla Model 3 they have hacked.
The researcher dungdm (@_piers2) of Team Viettel (@vcslab) exploited an uninitialized variable and a UAF bug to hack Oracle VirtualBox. He earned $40,000 and 4 Master of Pwn points.
Tanguy Dubroca (@SidewayRE) from Synacktiv was awarded $30,000 for demonstrating the exploitation of an incorrect pointer scaling zero-day leading to privilege escalation on Ubuntu Desktop. They earn $30,000 and 3 Master of Pwn points.
