CVE-2022-33180: Improper Authorization in Brocade Fabric OS
A vulnerability in Brocade Fabric OS CLI before Brocade Fabric OS v9.1.0, 9.0.1e, 8.2.3c, 8.2.0cbn5 could allow a local authenticated attacker to export out sensitive files with “seccryptocfg”, “configupload”.
AI Analysis
Technical Summary
CVE-2022-33180 is a medium-severity vulnerability affecting Brocade Fabric OS (FOS) versions prior to 9.1.0, 9.0.1e, 8.2.3c, and 8.2.0cbn5. The vulnerability arises from improper authorization controls within the Brocade Fabric OS command-line interface (CLI). Specifically, a local attacker with authenticated access to the system can exploit this flaw to export sensitive configuration files using commands such as “seccryptocfg” and “configupload”. These commands are intended for configuration management and security cryptographic settings export but lack sufficient authorization checks to restrict access to privileged users only. The vulnerability has a CVSS v3.1 base score of 5.5, reflecting a medium severity level. The attack vector is local (AV:L), requiring low attack complexity (AC:L) and low privileges (PR:L), but no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no direct impact on integrity or availability. No known exploits are currently reported in the wild. Brocade Fabric OS is widely used in storage area networks (SANs) for managing Fibre Channel switches and directors, which are critical infrastructure components in enterprise data centers. The ability to export sensitive files could lead to exposure of cryptographic keys, configuration details, or other sensitive data that could facilitate further attacks or unauthorized access.
Potential Impact
For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive storage network configurations and cryptographic materials. Many European enterprises, especially in sectors such as finance, healthcare, telecommunications, and manufacturing, rely on Brocade Fabric OS for their SAN infrastructure. Exposure of sensitive files could enable attackers to map network topologies, extract encryption keys, or gather intelligence for lateral movement within the network. This could ultimately lead to data breaches, intellectual property theft, or disruption of critical services. Given that the vulnerability requires local authenticated access, the threat is heightened if insider threats or compromised credentials are present. Additionally, organizations with remote management capabilities that do not adequately restrict access could be vulnerable to attackers gaining foothold through other means and then exploiting this flaw. The lack of impact on integrity and availability means the vulnerability is less likely to cause direct service disruption but remains critical for protecting sensitive information assets.
Mitigation Recommendations
Organizations should immediately verify their Brocade Fabric OS versions and plan to upgrade to the fixed versions 9.1.0, 9.0.1e, 8.2.3c, or 8.2.0cbn5 as provided by the vendor. Until patches are applied, strict access controls should be enforced on the CLI interface to limit authenticated user access only to trusted administrators. Implement multi-factor authentication (MFA) for all management interfaces to reduce the risk of credential compromise. Monitor and audit all CLI command usage, especially commands related to configuration export such as “seccryptocfg” and “configupload”, to detect unauthorized attempts. Network segmentation should be employed to isolate SAN management interfaces from general user networks. Additionally, review and harden user privilege assignments to ensure the principle of least privilege is enforced. If possible, disable or restrict the use of export commands for users who do not require them. Finally, conduct regular security awareness training to mitigate insider threats and ensure administrators understand the risks associated with improper authorization.
