## What is CVE-2024-31970?

CVE-2024-31970 is a high-severity vulnerability in n/a, published on 24 Jul 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

AdTran SRG 834-5 HDC17600021F1 devices (with SmartOS 11.1.1.1 and fixed in Version 12.1.3.1) have SSH enabled by default, accessible both over the LAN and the Internet. During a window of time when the device is being set up, it uses a default username and password combination of admin/admin with root-level privileges. An attacker can exploit this window to gain unauthorized root access by either modifying the existing admin account or creating a new account with equivalent privileges. This vulnerability allows attackers to execute arbitrary commands. NOTE: The vendor has disputed this, finding the report not applicable. According to AdTran, SSH has never been accessible (from WAN) on SmartOS official builds. Furthermore, the vendor adds that test build 11.1.0.101-202106231430 was never released to end users.

Weakness: CWE-863 (Incorrect Authorization)

Check this codebase for CVE-2024-31970 and fix it if it is affected.

What it is: CVE-2024-31970 is a high-severity vulnerability in n/a, published on 24 Jul 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-31970 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.
