Improper Control of Generation of Code ('Code Injection')
The website builder module in Dolibarr versions from 9.0.3 prior to 14.0.0 allows remote PHP code execution because of an incomplete protection mechanism in which system, exec, and shell_exec are blocked but backticks are not blocked.
CWE-94 - Code Injection
Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
