Create Hongdian Vulnerability CVE-2021-28149 : Hongdian H8922 3.0.5 devices allow Directory Traversal. The /log_download.cgi log export handler does not validate user input and allows a remote attacker with minimal privileges to download any file from the device by substituting ../ (e.g., ../../etc/passwd) This can be carried out with a web browser by changing the file name accordingly. Upon visiting log_download.cgi?type=../../etc/passwd and logging in, the web server will allow a download of the contents of the /etc/passwd file. CVE-2021-28150 : Hongdian H8922 3.0.5 devices allow the unprivileged guest user to read cli.conf (with the administrator password and other sensitive data) via /backup2.cgi. CVE-2021-28151 : Hongdian H8922 3.0.5 devices allow OS command injection via shell metacharacters into the ip-address (aka Destination) field to the tools.cgi ping command, which is accessible with the username guest and password guest.
