[Vulnerability Description]
CVE-2023-46383 : Insecure Permissions
Loytec LINX Configurator could be connected to Loytec devices with
an administrator credential, and it could configure device settings.
Since it uses HTTP Basic Authentication, which transmits usernames
and passwords in base64-encoded cleartext, so anyone could easily
steal credentials if they sniff network traffics. Once obtaining the
admin password, attackers could connect and control Loytec devices
via LINX configurator.
CVE-2023-46384 : Insecure Permissions
Following registry key contains hard-coded clear text admin password
for recently connected Loytec device. (password cache) If an attacker
succeeds in getting this registry key value, attackers could connect
and control Loytec devices via LINX configurator.
Key: ComputerHKEY_CURRENT_USERSOFTWARELOYTECLOYTEC LINX ConfiguratorOhioIni
Value name: ftp_pass
Value dada: <admin password>
CVE-2023-46385 : Insecure Permissions
When Loytec LINX Configurator connects to a device, it sends HTTP GET
request to login. Since cleartext password is passed as an URL parameter,
"password" without sufficient protection, anyone could easily steal
credentials if they sniff network traffics. Once obtaining the admin
password, attackers could connect and control Loytec devices via LINX
configurator.
