## What is CVE-2021-40661?

CVE-2021-40661 is a high-severity path traversal vulnerability in n/a, published on 31 Oct 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A remote, unauthenticated, directory traversal vulnerability was identified within the web interface used by IND780 Advanced Weighing Terminals Build 8.0.07 March 19, 2018 (SS Label 'IND780_8.0.07'), Version 7.2.10 June 18, 2012 (SS Label 'IND780_7.2.10'). It was possible to traverse the folders of the affected host by providing a traversal path to the 'webpage' parameter in AutoCE.ini This could allow a remote unauthenticated adversary to access additional files on the affected system. This could also allow the adversary to perform further enumeration against the affected host to identify the versions of the systems in use, in order to launch further attacks in future.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2021-40661 and fix it if it is affected.

What it is: CVE-2021-40661 is a high-severity path traversal vulnerability in n/a, published on 31 Oct 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-40661 exists.

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.
