- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Over the internet
- **Victim action needed:** Not needed
- **Fix available:** No

## What is CVE-2021-28674?

CVE-2021-28674 is a medium-severity missing authorization vulnerability in n/a, published on 27 Jul 2021. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The node management page in SolarWinds Orion Platform before 2020.2.5 HF1 allows an attacker to create or delete a node (outside of the attacker's perimeter) via an account with write permissions. This occurs because node IDs are predictable (with incrementing numbers) and the access control on Services/NodeManagement.asmx/DeleteObjNow is incorrect. To exploit this, an attacker must be authenticated and must have node management rights associated with at least one valid group on the platform.

Weakness: CWE-863 (Incorrect Authorization), CWE-330 (Use of Insufficiently Random Values)

```text
Check this codebase for CVE-2021-28674 and fix it if it is affected.

What it is: CVE-2021-28674 is a medium-severity missing authorization vulnerability in n/a, published on 27 Jul 2021. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2021-28674 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.
