## What is CVE-2018-15006?

CVE-2018-15006 is a medium-severity denial of service vulnerability in n/a, published on 28 Dec 2018. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The ZTE ZMAX Champ Android device with a build fingerprint of ZTE/Z917VL/fortune:6.0.1/MMB29M/20170327.120922:user/release-keys contains a pre-installed platform app with a package name of com.android.zte.hiddenmenu (versionCode=23, versionName=6.0.1) that contains an exported broadcast receiver app component named com.android.zte.hiddenmenu.CommandReceiver that is accessible to any app co-located on the device. This app component, when it receives a broadcast intent with a certain action string, will write a non-standard (i.e., not defined in Android Open Source Project (AOSP) code) command to the /cache/recovery/command file to be executed in recovery mode. Once the device boots into recovery mode, it will crash, boot into recovery mode, and crash again. This crash loop will keep repeating, which makes the device unusable. There is no way to boot into an alternate mode once the crash loop starts.

Check this codebase for CVE-2018-15006 and fix it if it is affected.

What it is: CVE-2018-15006 is a medium-severity denial of service vulnerability in n/a, published on 28 Dec 2018. 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-2018-15006 in the wild and no public exploit code.

Affected product: n/a. 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.
