Elefant: Unprotected Primary Channel
CVE-2024-50588 is a critical-severity unprotected primary channel vulnerability in Elefant from HASOMED, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 24.03.03 as the first without the flaw, so updating Elefant to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.7% chance of exploitation within 30 days, higher than 54% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Elefant to 24.03.03 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
An unauthenticated attacker with access to the local network of the medical office can use known default credentials to gain remote DBA access to the Elefant Firebird database. The data in the database includes patient data and login credentials among other sensitive data. In addition, this enables an attacker to create and overwrite arbitrary files on the server filesystem with the rights of the Firebird database ("NT AUTHORITY\SYSTEM").

The underlying weakness: Unprotected Primary Channel
The product uses a primary channel for administration or restricted functionality, but it does not properly protect the channel.
How developers prevent this class of flaw
- Do not expose administrative functionality on the user UI.
- Protect the administrative/restricted functionality with a strong authentication mechanism.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
