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.
