In firmware version MS_2.6.9900 of Columbia Weather MicroServer, a stored Cross-site scripting (XSS) vulnerability allows remote authenticated users to inject arbitrary web script via changestationname.php.

In firmware version MS_2.6.9900 of Columbia Weather MicroServer, a readouts_rd.php directory traversal issue makes it possible to read any file present on the underlying operating system.

In firmware version MS_2.6.9900 of Columbia Weather MicroServer, an authenticated web user can access an alternative configuration page config_main.php that allows manipulation of the device.

In firmware version MS_2.6.9900 of Columbia Weather MicroServer, the BACnet daemon does not properly validate input, which could allow a remote attacker to send specially crafted packets causing the device to become unavailable.

In firmware version MS_2.6.9900 of Columbia Weather MicroServer, an authenticated web user can pipe commands directly to the underlying operating system as user input is not sanitized in networkdiags.php.

In firmware version MS_2.6.9900 of Columbia Weather MicroServer, a networkdiags.php reflected Cross-site scripting (XSS) vulnerability allows remote authenticated users to inject arbitrary web script.

An unused function in MicroServer can start a reverse SSH connection to a vendor registered domain, without mutual authentication. An attacker on the local network with admin access to the web server, and the ability to manipulate DNS responses, can redirect the SSH connection to an attacker controlled device.

An unused webshell in MicroServer allows unlimited login attempts, with sudo rights on certain files and directories. An attacker with admin access to MicroServer can gain limited shell access, enabling persistence through reverse shells, and the ability to modify or remove data stored in the file system.
