## What is CVE-2023-33480?

CVE-2023-33480 is a high-severity vulnerability in n/a, published on 7 Nov 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

RemoteClinic 2.0 contains a critical vulnerability chain that can be exploited by a remote attacker with low-privileged user credentials to create admin users, escalate privileges, and execute arbitrary code on the target system via a PHP shell. The vulnerabilities are caused by a lack of input validation and access control in the staff/register.php endpoint and the edit-my-profile.php page. By sending a series of specially crafted requests to the RemoteClinic application, an attacker can create admin users with more privileges than their own, upload a PHP file containing arbitrary code, and execute arbitrary commands via the PHP shell.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type)

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.
