## What is CVE-2020-11629?

CVE-2020-11629 is a high-severity vulnerability in n/a, published on 7 Apr 2020. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

An issue was discovered in EJBCA before 6.15.2.6 and 7.x before 7.3.1.2. The External Command Certificate Validator, which allows administrators to upload external linters to validate certificates, is supposed to save uploaded test certificates to the server. An attacker who has gained access to the CA UI could exploit this to upload malicious scripts to the server. (Risks associated with this issue alone are negligible unless a malicious user already has gained access to the CA UI through other means, as a trusted user is already trusted to upload scripts by virtue of having access to the validator.)

Weakness: CWE-522 (Insufficiently Protected Credentials)

Check this codebase for CVE-2020-11629 and fix it if it is affected.

What it is: CVE-2020-11629 is a high-severity vulnerability in n/a, published on 7 Apr 2020. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-11629 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.
