Vulnerability from github – Published: 2017-10-24 18:33 – Updated: 2021-09-22 18:27

Summary

Deserialization Code Execution in js-yaml

Details

Versions 2.0.4 and earlier of js-yaml are affected by a code execution vulnerability in the YAML deserializer.

Proof of Concept

const yaml = require('js-yaml');

const x = `test: !!js/function >
function f() { 
console.log(1); 
}();`

yaml.load(x);

Recommendation

Update js-yaml to version 2.0.5 or later, and ensure that all instances where the .load() method is called are updated to use .safeLoad() instead.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
