Detailsinfo

A vulnerability, which was classified as problematic, was found in QUIC 17.4. This affects an unknown function of the component Latency Spin Bit. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. The summary by CVE is:

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."

The weakness was shared 02/21/2024. The advisory is shared at arrow.tudublin.ie. This vulnerability is uniquely identified as CVE-2023-50923 since 12/15/2023. Neither technical details nor an exploit are publicly available.

The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
