Technical ContextAI · show details
This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application. CodeIgniter is a PHP full-stack web framework. This vulnerability allows attackers to execute arbitrary code when you use Validation Placeholders. The vulnerability exists in the Validation library, and validation methods in the controller and in-model validation are also vulnerable because they use the Validation library internally. This issue is patched in version 4.3.5. Affected products include: Codeigniter. Version information: version 4.3.5..

Priority Score
Attack Technique
Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
