How to Fix CVE-2023-23619

To remediate this vulnerability, upgrade all affected @asyncapi/modelina dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@asyncapi/modelina fixed: 1.0.0 
npm install @asyncapi/modelina@1.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @asyncapi/modelina

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-23619, inspect your project dependencies using npm:

npm ls @asyncapi/modelina

Analyze the terminal output to locate any version of @asyncapi/modelina in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0), your application is affected.

Note: The npm ls @asyncapi/modelina command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In @asyncapi/modelina, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Anyone who is using the default presets and/or does not handle the functionality themself. ### Patches It is impossible to fully guard against this, because users have access to the original raw information. However, as of version 1, if you only access the constrained models, you will not encounter this issue. Further similar situations are NOT seen as a security issue, but intended behavior. ### Workarounds Fully custom presets that change the entire rendering process which can then escape the user input. ### For more information Even though that I changed all the presets here, the vulnerability is still present throughout. I am using a JSON Schema here for simplicity. ```ts const jsonSchemaDoc = { $id: 'CustomClass', type: 'object', properties: { 'property: any; \n constructor(){console.log("injected")} \n private _temp': { type: 'string' }, } }; generator = new TypeScriptGenerator( { presets: [ { class: { property({ propertyName, content }) { return `private ${propertyName}: any;`; }, ctor() { return ''; }, getter() { return ''; }, setter() { return ''; } } } ] } ); const inputModel = await generator.process(jsonSchemaDoc); ``` This would render ```ts export class CustomClass { private property: any; constructor(){console.log("injected")} private _temp: any; private additionalProperties: any; } ```
