Exploitation: There is no known exploitation of CVE-2018-7824 in the wild and no public exploit code.

Affected product: Schneider Electric Modbus Serial Driver (For 64-bit Windows OS:V3.17 IE 37 and prior , For 32-bit Windows OS:V2.17 IE 27 and prior, and as part of the Driver Suite version:V14.12 and prior). 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.
