Dozens of Unpatched Flaws Expose Security Cameras Made by Defunct Company Zavio

IoT firmware analysis platform provider BugProve has disclosed the details of dozens of vulnerabilities discovered by its researchers in security cameras made by Zavio. Zavio is a defunct Chinese company, but its security cameras are reportedly still deployed in the United States and Europe, which is why it’s important to raise awareness about the vulnerabilities. Since Zavio has been shut down, BugProve has worked with CCTV Camera Pros, the main distributor of Zavio cameras in North America, to verify the vulnerabilities, and with the US Cybersecurity and Infrastructure Security Agency (CISA) to coordinate the disclosure and obtain CVE identifiers for the flaws. BugProve has identified more than 34 memory corruption and command injection vulnerabilities affecting various Zavio IP camera models, specifically a daemon called ‘Onvif’, which is used for integrations with various surveillance systems. According to the cybersecurity firm, seven of the vulnerabilities can be exploited for unauthenticated remote code execution with root privileges. These types of flaws can typically enable attackers to take complete control of the targeted device.
