Vulnerability from github – Published: 2024-11-08 12:31 – Updated: 2025-11-04 00:31

Details

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".

Severity

7.8 (High)

CVE-2024-50590 (GCVE-0-2024-50590)

Vulnerability from cvelistv5 – Published: 2024-11-08 11:45 – Updated: 2025-11-03 22:28

Title

Local Privilege Escalation via Weak Service Binary Permissions

Summary

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".

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
