How to Fix CVE-2024-45311

To remediate this vulnerability, upgrade all affected Quinn proto dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

quinn-proto fixed: 0.11.7 
Upgrade quinn-proto to 0.11.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for quinn-proto

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-45311, inspect your project dependencies for Quinn proto:

inspect dependencies for quinn-proto

Analyze the terminal output to locate any version of Quinn proto in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.11.7), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-670: Always-Incorrect Control Flow Implementation, where the code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated. In Quinn proto, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary As of quinn-proto 0.11, it is possible for a server to `accept()`, `retry()`, `refuse()`, or `ignore()` an `Incoming` connection. However, calling `retry()` on an unvalidated connection exposes the server to a likely panic in the following situations: - Calling `refuse` or `ignore` on the resulting validated connection, if a duplicate initial packet is received - This issue can go undetected until a server's `refuse()`/`ignore()` code path is exercised, such as to stop a denial of service attack. - Accepting when the initial packet for the resulting validated connection fails to decrypt or exhausts connection IDs, if a similar initial packet that successfully decrypts and doesn't exhaust connection IDs is received. - This issue can go undetected if clients are well-behaved. The former situation was observed in a real application, while the latter is only theoretical. ### Details Location of panic: https://github.com/quinn-rs/quinn/blob/bb02a12a8435a7732a1d762783eeacbb7e50418e/quinn-proto/src/endpoint.rs#L213 ### Impact Denial of service for internet-facing server
