Title
License forgery in Brocade Fabric OS (FOS) hardware platforms running any version of Brocade Fabric OS software,
Summary
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)
