How to Fix CVE-2020-7617

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

ini-parser fixed: Latest secure release 
npm install ini-parser@Latest secure release
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 ini-parser

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-7617, inspect your project dependencies using npm:

npm ls ini-parser

Analyze the terminal output to locate any version of Ini parser in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls ini-parser 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-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes, where the product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified. In Ini parser, 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

All versions of `ini-parser` are vulnerable to prototype pollution. The `parse` function does not restrict the modification of an Object's prototype, which may allow an attacker to add or modify an existing property that will exist on all objects. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
