## What is CVE-2017-7240?

CVE-2017-7240 is a high-severity path traversal vulnerability in n/a, published on 24 Mar 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered on Miele Professional PST10 devices. The corresponding embedded webserver "PST10 WebServer" typically listens to port 80 and is prone to a directory traversal attack; therefore, an unauthenticated attacker may be able to exploit this issue to access sensitive information to aide in subsequent attacks. A Proof of Concept is GET /../../../../../../../../../../../../etc/shadow HTTP/1.1. This affects PG8527 devices 2.02 before 2.12, PG8527 devices 2.51 before 2.61, PG8527 devices 2.52 before 2.62, PG8527 devices 2.54 before 2.64, PG8528 devices 2.02 before 2.12, PG8528 devices 2.51 before 2.61, PG8528 devices 2.52 before 2.62, PG8528 devices 2.54 before 2.64, PG8535 devices 1.00 before 1.10, PG8535 devices 1.04 before 1.14, PG8536 devices 1.10 before 1.20, and PG8536 devices 1.14 before 1.24.

Check this codebase for CVE-2017-7240 and fix it if it is affected.

What it is: CVE-2017-7240 is a high-severity path traversal vulnerability in n/a, published on 24 Mar 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-7240 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.
