Thousands of SonicWall network security devices are currently exposed to severe vulnerabilities, with over 20,000 running outdated firmware that no longer receives vendor support. This puts countless organizations at risk of unauthorized access and potential data breaches.
Key Findings of the Study
- A Bishop Fox study identified more than 25,000 SonicWall SSLVPN devices exposed to the internet, making them easy targets for cybercriminals.
- The research analyzed over 430,000 SonicWall devices globally and found that 39% of the exposed devices were running Series 7 firewalls, many of which lacked the latest security patches.
- Over 20,000 devices were found to be running software versions no longer supported by SonicWall, with older Series 5 and Series 6 devices being the most at risk.
Impact of Vulnerabilities
The study highlighted that many of these devices remain susceptible to exploits, including authentication bypasses and heap overflow bugs disclosed earlier this year. Attackers could use these flaws to gain unauthorized access to networks, particularly when both SSL VPN and administration interfaces are exposed online.
