Code Evaluation (Node.js)
Severity: Critical
Summary
Netsparker identified a possible code (Node.js) evaluation, which occurs when input data is run as code.
Even though Netsparker believes there is a code (Node.js) evaluation in here, it could not confirm it. There can be numerous reasons for Netsparker not being able to confirm it. We strongly recommend you investigate the issue manually to ensure it is a remote code (Node.js) evaluation and needs to be addressed.
Impact
An attacker can execute arbitrary Node.js code on the system. The attacker may also be able to execute arbitrary system commands.
Remediation
Do not accept input from end users that will be directly interpreted as source code. If this is a business requirement, validate all the input on the application and remove all the data that could be directly interpreted as Node.js source code.
Required Skills for Successful Exploitation
This vulnerability is not difficult to leverage. Node.js is a high level language for which there are vast resources available. Successful exploitation requires knowledge of the programming language, access to the source code or the ability to produce source code for use in such attacks, and minimal attack skills.
