## What is CVE-2023-42802?

CVE-2023-42802 is a critical vulnerability in Glpi-Project Glpi, published on 2 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

GLPI is a free asset and IT management software package. Starting in version 10.0.7 and prior to version 10.0.10, an unverified object instantiation allows one to upload malicious PHP files to unwanted directories. Depending on web server configuration and available system libraries, malicious PHP files can then be executed through a web server request. Version 10.0.10 fixes this issue. As a workaround, remove write access on `/ajax` and `/front` files to the web server.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type), CWE-20 (Improper Input Validation)

What it is: CVE-2023-42802 is a critical vulnerability in Glpi-Project Glpi, published on 2 Nov 2023. 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-2023-42802 in the wild and no public exploit code.

Affected product: Glpi-Project Glpi. 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.
