## What is CVE-2023-48310?

CVE-2023-48310 is a critical command injection vulnerability in NC3-LU TestingPlatform, published on 20 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

TestingPlatform is a testing platform for Internet Security Standards. Prior to version 2.1.1, user input is not filtered correctly. Nmap options are accepted. In this particular case, the option to create log files is accepted in addition to a host name (and even without). A log file is created at the location specified. These files are created as root. If the file exists, the existing file is being rendered useless. This can result in denial of service. Additionally, input for scanning can be any CIDR blocks passed to nmap. An attacker can scan 0.0.0.0/0 or even local networks. Version 2.1.1 contains a patch for this issue.

Weakness: CWE-20 (Improper Input Validation)

What it is: CVE-2023-48310 is a critical command injection vulnerability in NC3-LU TestingPlatform, published on 20 Nov 2023. 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-2023-48310 exists.

Affected product: NC3-LU TestingPlatform. 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.
