title: Command injection via Advanced Networking route add functionality
description: An authenticated attacker can send a specially crafted route to the “edit_route.cgi” binary and have it execute shell commands. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.303 for the LP series and 1.297 for the EP series. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable.

solutions: Update to the latest version of firmware
workarounds: Disable the controller's Web Server.
When the controller is configured to disable web access, you cannot remotely login into the controller’s web page.
1. Login to controller web pages
2. Go to “Users” Tab
3. Near bottom of the Users page, check option to “Disable Web Server”
4. Then select “Submit” at the bottom of the page
5. Then select “Apply Settings” tab
6. And on that page, select button “Apply Settings, Reboot”
The Controller will apply the new setting and reboot. Web login will be disabled until switch 1 is physically turned ON, on the controller.
