Google’s Quick Share Vulnerabilities Let Attackers Execute Remote Code

After reverse-engineering the Quick Share’s communication protocol, researchers discovered multiple vulnerabilities including unauthorized file writes, forced Wi-Fi connections, and denial-of-service conditions. These issues could be chained together to remotely execute code on Windows systems with Quick Share installed. Google addressed these vulnerabilities with two CVEs. The findings highlight potential areas for exploitation in Quick Share, including its application-layer protocol for file transmission. To determine these threats, researchers developed a DLL to intercept Read and Write functions, logging packet contents for analysis.
