Vulnerability from github – Published: 2026-09-01 21:31 – Updated: 2026-09-01 21:31

Details

Vulnerabilities in an API endpoint of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to conduct a denial of service attack. Successful exploitation could allow an attacker to make limited unauthorized modifications to the underlying operating system and disrupt the availability of the affected system, requiring manual intervention to restore functionality.

Severity

8.2 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H

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.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
