name: Hongdian H8922 3.0.5 Devices - Local File Inclusion
|
|
author: gy741

severity: medium

description: |
|
|
Hongdian H8922 3.0.5 devices are vulnerable to local file inclusion. 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.
