Hackers have earned roughly $350,000 in rewards after demonstrating successful exploits against a variety of devices on the second day of the Zero Day Initiative’s Pwn2Own Toronto 2023 competition.
Just as on the first day of the hacking contest, NAS devices, printers, smart speakers, and mobile phones were hacked on Wednesday, with successful exploits also demonstrated against routers.
The highest reward went to Chris Anastasio, who earned $100,000 for exploits targeting a vulnerability in the P-Link Omada Gigabit router and one in the Lexmark CX331adwe printer, ZDI announced.
On the second day of the competition, a Devcore intern earned $50,000 for a stack buffer overflow issue in the TP-Link Omada Gigabit router and two flaws in the QNAP TS-464 NAS device.
Team Orca of Sea Security also earned $50,000 on Wednesday, for a bug in the Synology RT6600ax router and a three-bug chain against the QNAP TS-464 NAS device.
Rewards of $30,000 were handed out for a command injection in the Wyze Cam v3 security camera and an out-of-bounds write issue in the Sonos Era 100 smart speaker.
ZDI also announced high rewards for an improper input validation bug and a permissive list of allowed inputs flaw in Samsung Galaxy S23 ($25,000), a stack-based buffer overflow issue in the HP Color LaserJet Pro MFP 4301fdw ($20,000), and a stack-based buffer overflow vulnerability in the Canon imageCLASS MF753Cdw printer ($10,000).
Additionally, multiple low-tier rewards were handed out for exploits targeting known vulnerabilities in QNAP TS-464, Wyze Cam v3, Synology BC500, and Canon imageCLASS MF753Cdw.
Overall, ZDI says, participating hackers have earned more than $800,000 in rewards on the first two days of the competition, which is set to conclude on Friday.
