Vulnerability from github – Published: 2022-05-14 00:01 – Updated: 2022-05-25 22:54

Summary

Prototype Pollution in convict

Details

This affects the package convict before 6.2.3. This is a bypass of CVE-2022-22143. The fix introduced, relies on the startsWith method and does not prevent the vulnerability: before splitting the path, it checks if it starts with proto or this.constructor.prototype. To bypass this check it's possible to prepend the dangerous paths with any string value followed by a dot, like for example foo.proto or foo.this.constructor.prototype.

Severity

9.8 (Critical)

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.
