## What is CVE-2023-38291?

CVE-2023-38291 is a high-severity vulnerability in n/a, published on 22 Apr 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An issue was discovered in a third-party component related to ro.boot.wifimacaddr, shipped on devices from multiple device manufacturers. Various software builds for the following TCL devices (30Z and 10L) and Motorola devices (Moto G Pure and Moto G Power) leak the Wi-Fi MAC address to a system property that can be accessed by any local app on the device without any permissions or special privileges. Google restricted third-party apps from directly obtaining non-resettable device identifiers in Android 10 and higher, but in these instances they are leaked by a high-privilege process and can be obtained indirectly. The software build fingerprints for each confirmed vulnerable device are as follows: TCL A3X (TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vAAZ:user/release-keys, TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vAB3:user/release-keys, TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vAB7:user/release-keys, TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vABA:user/release-keys, TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vABM:user/release-keys, TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vABP:user/release-keys, and TCL/A600DL/Delhi_TF:11/RKQ1.201202.002/vABS:user/release-keys); TCL 10L (TCL/T770B/T1_LITE:10/QKQ1.200329.002/3CJ0:user/release-keys and TCL/T770B/T1_LITE:11/RKQ1.210107.001/8BIC:user/release-keys); Motorola Moto G Pure (motorola/ellis_trac/ellis:11/RRHS31.Q3-46-110-2/74844:user/release-keys, motorola/ellis_trac/ellis:11/RRHS31.Q3-46-110-7/5cde8:user/release-keys, motorola/ellis_trac/ellis:11/RRHS31.Q3-46-110-10/d67faa:user/release-keys, motorola/ellis_trac/ellis:11/RRHS31.Q3-46-110-13/b4a29:user/release-keys, motorola/ellis_trac/ellis:12/S3RH32.20-42-10/1c2540:user/release-keys, motorola/ellis_trac/ellis:12/S3RHS32.20-42-13-2-1/6368dd:user/release-keys, motorola/ellis_a/ellis:11/RRH31.Q3-46-50-2/20fec:user/release-keys, motorola/ellis_vzw/ellis:11/RRH31.Q3-46-138/103bd:user/release-keys, motorola/ellis_vzw/ellis:11/RRHS31.Q3-46-138-2/e5502:user/release-keys, and motorola/ellis_vzw/ellis:12/S3RHS32.20-42-10-14-2/5e0b0:user/release-keys); and Motorola Moto G Power (motorola/tonga_g/tonga:11/RRQ31.Q3-68-16-2/e5877:user/release-keys and motorola/tonga_g/tonga:12/S3RQS32.20-42-10-6/f876d3:user/release-keys). This malicious app reads from the "ro.boot.wifimacaddr" system property to indirectly obtain the Wi-Fi MAC address.

Weakness: CWE-276 (Incorrect Default Permissions)

Check this codebase for CVE-2023-38291 and fix it if it is affected.

What it is: CVE-2023-38291 is a high-severity vulnerability in n/a, published on 22 Apr 2024. 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-2023-38291 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.
