Description

An issue was discovered in AvertX Auto focus Night Vision HD Indoor/Outdoor IP Dome Camera HD838 and Night Vision HD Indoor/Outdoor Mini IP Bullet Camera HD438. They do not require users to change the default password for the admin account. They only show a pop-up window suggesting a change but there's no enforcement. An administrator can click Cancel and proceed to use the device without changing the password. Additionally, they disclose the default username within the login.js script. Since many attacks for IoT devices, including malware and exploits, are based on the usage of default credentials, it makes these cameras an easy target for malicious actors.

3 Vulnerabilities Found on AvertX IP Cameras

Unit 42 disclosed three vulnerabilities (CVE-2020-11623/4/5) in AvertX HD838 and 438IR IP cameras; AvertX has released patches.

Palo Alto Networks Unit 42 researchers found three vulnerabilities in AvertX HD838 and 438IR outdoor surveillance cameras, which are rebranded Hikvision products: CVE-2020-11625 (user enumeration), CVE-2020-11624 (weak password requirements), and CVE-2020-11623 (exposed dangerous method/function). User enumeration responses facilitate brute-force attacks, the default admin credentials (admin/1234) are never enforced to change, and physical access to an exposed UART interface allows bootloader access and configuration modification. AvertX released a patch, removed the UART connector, and disabled the interface in the latest production batch.
