CVE-2022-39294
7.5 · HIGHOverview
CVE-2022-39294 is a high-severity vulnerability affecting conduit-hyper_project conduit-hyper. It was published on October 31, 2022 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
conduit-hyper integrates a conduit application with the hyper server. Prior to version 0.4.2, `conduit-hyper` did not check any limit on a request's length before calling [`hyper::body::to_bytes`](https://docs.rs/hyper/latest/hyper/body/fn.to_bytes.html). An attacker could send a malicious request with an abnormally large `Content-Length`, which could lead to a panic if memory allocation failed for that request. In version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per request, otherwise returning status 400 ("Bad Request"). This crate is part of the implementation of Rust's [crates.io](https://crates.io/), but that service is not affected due to its existing cloud infrastructure, which already drops such malicious requests. Even with the new limit in place, `conduit-hyper` is not recommended for production use, nor to directly serve the public Internet.
Remediation
Check the references section for vendor advisories and patches from conduit-hyper_project. Update conduit-hyper to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
