CVE-2025-1053 is a high-severity vulnerability affecting Brocade SANnav versions prior to 2.3.1b. The vulnerability is classified under CWE-532, which involves the insertion of sensitive information into log files. Specifically, during certain error conditions that occur during the installation or upgrade of Brocade SANnav, the encryption key used by the system can be inadvertently written into the Brocade SANnav supportsave logs. These supportsave files are typically used for troubleshooting and can be accessed by administrators or attackers with privileged access to the SANnav database. If an attacker gains privileged access to the Brocade SANnav database, they could extract this encryption key from the supportsave logs. With the encryption key, the attacker could then decrypt stored passwords used by Brocade SANnav, potentially compromising the confidentiality and integrity of the storage area network (SAN) management environment. The vulnerability does not require authentication but does require privileged access to the SANnav database, and user interaction is needed to trigger the error condition that causes the key to be logged. The CVSS 4.0 score of 8.6 reflects the high impact on confidentiality and integrity, with a complex attack vector and high scope impact. No known exploits are currently reported in the wild, but the potential for significant compromise exists if exploited.

For European organizations relying on Brocade SANnav for SAN management, this vulnerability poses a significant risk. SANnav is used to manage and monitor storage networks, which are critical for data availability and integrity in enterprise environments. If an attacker obtains the encryption key and decrypts stored passwords, they could gain unauthorized access to SAN management functions, potentially leading to data breaches, unauthorized data manipulation, or disruption of storage services. This could impact confidentiality of sensitive data, integrity of storage configurations, and availability of critical storage resources. Given the reliance on SAN infrastructure in sectors such as finance, healthcare, and government within Europe, exploitation could lead to regulatory non-compliance (e.g., GDPR), financial losses, and reputational damage. The requirement for privileged access limits the attack surface but insider threats or lateral movement by attackers who have already compromised internal systems could leverage this vulnerability to escalate privileges and access sensitive storage management credentials.

European organizations should prioritize upgrading Brocade SANnav to version 2.3.1b or later, where this vulnerability is addressed. Until patching is possible, organizations should restrict access to the SANnav database and supportsave files to the minimum necessary personnel, enforcing strict access controls and monitoring. Implementing robust logging and alerting on access to supportsave files can help detect suspicious activity. Additionally, organizations should audit and rotate encryption keys and passwords used by SANnav regularly to limit the window of exposure. Employing network segmentation to isolate SAN management interfaces and databases from general user networks can reduce the risk of unauthorized access. Finally, conducting internal security awareness training to mitigate insider threats and ensuring that error handling and logging configurations are reviewed to avoid leakage of sensitive information are recommended.
