Vulnerability from github – Published: 2023-05-18 17:29 – Updated: 2023-05-18 17:29

Summary

SwiftNIO vulnerable to HTTP request smuggling using malformed Transfer-Encoding header

Details

Impact

Affected SwiftNIO systems are vulnerable to request smuggling attacks, in which they parse a given HTTP message differently from other network parties, potentially seeing a different number of requests than other servers. This can lead to failures of authentication, routing, and other issues.

This vulnerability can be found in the bundled copy of the Node.JS HTTP parser used in the NIOHTTP1 module.

Workarounds

No workaround is available, users must upgrade.

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.
