## What is CVE-2022-24688?

CVE-2022-24688 is a high-severity vulnerability in n/a, published on 18 Jul 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An issue was discovered in DSK DSKNet 2.16.136.0 and 2.17.136.5. The Touch settings allow unrestricted file upload (and consequently Remote Code Execution) via PDF upload with PHP content and a .php extension. The attacker must hijack or obtain privileged user access to the Parameters page in order to exploit this issue. (That can be easily achieved by exploiting the Broken Access Control with further Brute-force attack or SQL Injection.) The uploaded file is stored within the database and copied to the sync web folder if the attacker visits a certain .php?action= page.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type)

Check this codebase for CVE-2022-24688 and fix it if it is affected.

What it is: CVE-2022-24688 is a high-severity vulnerability in n/a, published on 18 Jul 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-24688 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.
