GHSA-48F4-CX87-W7MH

Vulnerability from github – Published: 2024-02-21 00:31 – Updated: 2024-12-04 21:30

Details

In QUIC in RFC 9000, the Latency Spin Bit specification (section 17.4) does not strictly constrain the bit value when the feature is disabled, which might allow remote attackers to construct a covert channel with data represented as changes to the bit value. NOTE: The "Sheridan, S., Keane, A. (2015). In Proceedings of the 14th European Conference on Cyber Warfare and Security (ECCWS), University of Hertfordshire, Hatfield, UK." paper says "Modern Internet communication protocols provide an almost infinite number of ways in which data can be hidden or embed whithin seemingly normal network traffic."

Severity

4.3 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N

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.
