CVE-2019-9506 Weak cryptography in BR/EDR
High 7.6
Published
Updated
Check this codebase for CVE-2019-9506 and fix it if it is affected.
What it is: CVE-2019-9506 is a high-severity vulnerability in Apple Iphone Os, published on 14 Aug 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-9506 in the wild and no public exploit code.
Affected product: Apple Iphone Os. No package-level version data is available, so check the vendor advisory linked from the reference page.
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.

What is CVE-2019-9506?
CVE-2019-9506 is a high-severity vulnerability in Apple Iphone Os, published on 14 Aug 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.
