## What is CVE-2022-25165?

CVE-2022-25165 is a high-severity vulnerability in n/a, published on 14 Apr 2022. 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 Amazon AWS VPN Client 2.0.0. A TOCTOU race condition exists during the validation of VPN configuration files. This allows parameters outside of the AWS VPN Client allow list to be injected into the configuration file prior to the AWS VPN Client service (running as SYSTEM) processing the file. Dangerous arguments can be injected by a low-level user such as log, which allows an arbitrary destination to be specified for writing log files. This leads to an arbitrary file write as SYSTEM with partial control over the files content. This can be abused to cause an elevation of privilege or denial of service.

Weakness: CWE-367 (Time-of-check Time-of-use (TOCTOU) Race Condition)

Check this codebase for CVE-2022-25165 and fix it if it is affected.

What it is: CVE-2022-25165 is a high-severity vulnerability in n/a, published on 14 Apr 2022. 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-2022-25165 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.
