- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 8 Oct 2024
- **Updated:** 21 Nov 2025

## What is CVE-2024-9622?

CVE-2024-9622 is a medium-severity denial of service vulnerability in Red Hat JBoss Data Grid 7, published on 8 Oct 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A vulnerability was found in the resteasy-netty4 library arising from improper handling of HTTP requests using smuggling techniques. When an HTTP smuggling request with an ASCII control character is sent, it causes the Netty HttpObjectDecoder to transition into a BAD_MESSAGE state. As a result, any subsequent legitimate requests on the same connection are ignored, leading to client timeouts, which may impact systems using load balancers and expose them to risk.

Weakness: CWE-444 (Inconsistent Interpretation of HTTP Requests)

Check this codebase for CVE-2024-9622 and fix it if it is affected.

What it is: CVE-2024-9622 is a medium-severity denial of service vulnerability in Red Hat JBoss Data Grid 7, published on 8 Oct 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-9622 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.jboss.resteasy:resteasy-netty4-cdi (Maven): affected all versions; no fix listed
- org.jboss.resteasy:resteasy-netty4-cdi (Maven): affected all versions; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
