Improper Control of Dynamically-Managed Code Resources vulnerability in Crafter Studio of CrafterCMS allows authenticated developers to execute OS commands via Groovy Sandbox Bypass.
By inserting malicious Groovy elements, an attacker may bypass Sandbox restrictions and obtain RCE (Remote Code Execution).
This issue affects CrafterCMS: from 4.0.0 through 4.2.2.
The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.
