The template file is stored in the template management module and can be accessed via the get_template() function. This allows an attacker to inject their own template and execute code on the system. There is no security restriction on the template file and any template can be accessed. All that is needed is to place a malicious template in the system. You should always keep your operating system, applications, and dependencies up to date. When you install a new package, make sure that it comes from a trusted source. To be on the safe side, you can take the following steps: Ensure that you have installed the latest version of UCMS. Install the latest version of the template management module. Make sure that you have updated the template management module.
In order to exploit this vulnerability, the attacker must be able to access the system. The attacker must have access to the system in order to place malicious template file. The template file can be accessed by any user on the system.
Vulnerability Scenario
An attacker has executed a malicious template file and is able to gain full access to the system.
Checklist:
Prevent a Template Attack
The following are the steps that you can take to prevent a template attack: Keep the system up to date. Check your network connection and make sure it is open.
To be on the safe side, you can do the following: Ensure that you have installed the latest version of UCMS. Install the latest version of the template management module. Update the template management module. Ensure that you have updated UCMS and all its dependencies.
CVE-2023-42235

What is SSB (Secure Socket Boot)?
Secure Socket Boot (SSB) is a method of authenticating network traffic to ensure that only authorized users can modify files and process commands on a system. SSB uses the Secure Sockets Layer protocol to encrypt communication between two parties.
The attacker must be able to access the system in order to place malicious template file. The template file can be accessed by any user on the system.
