Vulnerability from github – Published: 2023-12-06 03:30 – Updated: 2023-12-06 03:30

Details

Brocade Fabric OS (FOS) hardware platforms running any version of Brocade Fabric OS software, which supports the license string format; contain cryptographic issues that could allow for the installation of forged or fraudulent license keys. This would allow attackers or a malicious party to forge a counterfeit license key that the Brocade Fabric OS platform would authenticate and activate as if it were a legitimate license key.

Severity

6.4 (Medium)


                  
                    CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/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.
