## What is CVE-2024-50590?

CVE-2024-50590 is a high-severity vulnerability in HASOMED Elefant, published on 8 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Attackers with local access to the medical office computer can 
escalate their Windows user privileges to "NT AUTHORITY\SYSTEM" by 
overwriting one of two Elefant service binaries with weak permissions. The default installation directory of Elefant is "C:\Elefant1" which is 
writable for all users. In addition, the Elefant installer registers two
 Firebird database services which are running as “NT AUTHORITY\SYSTEM”. 

Path: C:\Elefant1\Firebird_2\bin\fbserver.exe

Path: C:\Elefant1\Firebird_2\bin\fbguard.exe

Both service binaries are user writable. This means that a local 
attacker can rename one of the service binaries, replace the service 
executable with a new executable, and then restart the system. Once the 
system has rebooted, the new service binary is executed as "NT 
AUTHORITY\SYSTEM".

Weakness: CWE-732 (Incorrect Permission Assignment for Critical Resource), CWE-276 (Incorrect Default Permissions), CWE-250 (Execution with Unnecessary Privileges)

Check this codebase for CVE-2024-50590 and fix it if it is affected.

What it is: CVE-2024-50590 is a high-severity vulnerability in HASOMED Elefant, published on 8 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-50590 exists.

Affected product: HASOMED Elefant. 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.
