## What is CVE-2022-30117?

CVE-2022-30117 is a critical path traversal vulnerability in Concretecms Concrete Cms, published on 24 Jun 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Concrete 8.5.7 and below as well as Concrete 9.0 through 9.0.2 allow traversal in /index.php/ccm/system/file/upload which could result in an Arbitrary File Delete exploit. This was remediated by sanitizing /index.php/ccm/system/file/upload to ensure Concrete doesn’t allow traversal and by changing isFullChunkFilePresent to have an early false return when input doesn't match expectations.Concrete CMS Security team ranked this 5.8 with CVSS v3.1 vector AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:H.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2022-30117 and fix it if it is affected.

What it is: CVE-2022-30117 is a critical path traversal vulnerability in Concretecms Concrete Cms, published on 24 Jun 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-30117 in the wild and no public exploit code.

Affected packages and fixed versions:
- concrete5/core (Packagist): affected all versions; fixed in 8.5.8
- concrete5/core (Packagist): affected all versions; fixed in 8.5.8
- concrete5/core (Packagist): affected from 9.0.0; fixed in 9.1.0
- concrete5/core (Packagist): affected from 9.0.0; fixed in 9.1.0

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.
