Detailsinfo

A vulnerability classified as very critical was found in NASA Fprime-gds up to 3.4.3. This vulnerability affects an unknown code block of the file src/fprime_gds/flask/app.py of the component Flask Application. The manipulation with an unknown input leads to a hard-coded key vulnerability. The CWE definition for the vulnerability is CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Multiple vulnerabilities in NASA fprime-gds through 3.4.3 allow an unauthenticated remote attacker to achieve arbitrary code execution on the ground station host and inject arbitrary commands to connected spacecraft. The Flask application in src/fprime_gds/flask/app.py applies no authentication to any endpoint. A path traversal in src/fprime_gds/flask/updown.py allows reading and writing arbitrary files outside the upload directory. A hardcoded secret key (CWE-321) in the application enables session forgery. Chained together, these vulnerabilities allow complete compromise of the ground data system and any spacecraft under its control.

The advisory is available at github.com. This vulnerability was named CVE-2026-72577 since 08/10/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/10/2026). This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
