Security researchers have identified four zero-day vulnerabilities in OpenVPN, affecting millions of devices worldwide. These vulnerabilities, named OVPNX, impact various operating systems, including Windows, iOS, macOS, Android, and BSD. The technical breakdown reveals complex flaws exploiting the VPN software's privilege levels and integration with operating system APIs
One of the critical vulnerabilities allows remote code execution through a stack overflow, leading to system service crashes and potential control by attackers. The impact on companies includes data breaches, unauthorized access, system takeovers, operational disruptions, and financial losses. Mitigation strategies involve updating OpenVPN, enforcing strict access controls, conducting security audits, and using IDS. The upcoming security conference will feature a live demonstration of the exploit chain to raise awareness and prompt proactive security measures against these potent threats in the digital age. https://cybersecuritynews.com/openvpn-zero-day-flaws/
