CVE-2025-58380 is a path traversal vulnerability identified in Brocade Fabric OS versions before 9.2.1, classified under CWE-35. The issue arises from improper handling of path variables when using the shell command 'grep' by an authenticated attacker with administrative privileges. By manipulating these path variables, the attacker can traverse upwards in the directory hierarchy or access directories outside the intended scope, potentially reading sensitive files or configuration data. The vulnerability requires local admin privileges on the system, meaning the attacker must already have significant access to the device. The CVSS v4.0 score of 4.6 reflects a medium severity, indicating limited impact due to the prerequisite of high privileges and lack of user interaction or network-based exploitation. The vulnerability does not affect system integrity or availability but poses a confidentiality risk by enabling unauthorized file access. No public exploits have been reported, and no patches are linked in the provided data, but upgrading to Fabric OS 9.2.1 or later is expected to remediate the issue. Brocade Fabric OS is widely used in storage area networks (SANs) for enterprise data centers, making this vulnerability relevant for organizations relying on Brocade SAN infrastructure.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive configuration files or credentials stored on Brocade Fabric OS devices. Since these devices often manage critical storage infrastructure, exposure of such information could facilitate further attacks, including lateral movement within the network or compromise of storage data confidentiality. Although exploitation requires admin privileges, insider threats or attackers who have already gained elevated access could leverage this flaw to escalate their capabilities. The impact is primarily on confidentiality, with no direct effect on system availability or integrity. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face regulatory and reputational risks if sensitive data is exposed. The lack of known exploits reduces immediate risk but does not eliminate the need for proactive remediation.

1. Upgrade Brocade Fabric OS to version 9.2.1 or later, where the vulnerability is fixed. 2. Limit administrative shell access strictly to trusted and trained personnel to reduce the risk of misuse. 3. Implement robust monitoring and logging of admin shell commands to detect unusual path traversal attempts. 4. Enforce strict access controls and network segmentation around SAN management interfaces to prevent unauthorized access. 5. Conduct regular audits of Fabric OS configurations and access permissions to identify potential privilege escalations. 6. Educate administrators about the risks of path traversal and the importance of following secure operational procedures when using shell commands. 7. If upgrading is not immediately possible, consider disabling or restricting the use of the vulnerable 'grep' command or shell access where feasible.
