CVE-2025-1053 in SANnav
Summary
by MITRE • 02/14/2025
Under certain error conditions at time of SANnav installation or upgrade, the encryption key can be written into and obtained from a Brocade SANnav supportsave. An attacker with privileged access to the Brocade SANnav database could use the encryption key to obtain passwords used by Brocade SANnav.

The vulnerability identified as CVE-2025-1053 represents a critical security flaw in Brocade SANnav systems that manifests during installation or upgrade processes under specific error conditions. This weakness stems from improper handling of encryption keys within the supportsave file mechanism, creating a scenario where sensitive cryptographic material becomes accessible to unauthorized parties. The vulnerability is particularly concerning because it leverages legitimate system operations to expose critical security components, making it difficult to detect and mitigate through conventional security measures.
The technical implementation of this flaw involves the inadvertent writing of encryption keys into supportsave files when installation or upgrade processes encounter errors. This behavior violates fundamental security principles by creating persistent exposure of cryptographic material that should remain protected throughout the system lifecycle. The encryption key stored within these supportsave files can be extracted and subsequently used to decrypt passwords that are stored within the Brocade SANnav database. This creates a direct pathway for privilege escalation and credential theft, as the attacker can leverage the extracted key to access authentication credentials used by the SANnav system.
From an operational impact perspective, this vulnerability enables attackers with privileged access to the Brocade SANnav database to escalate their privileges and gain unauthorized access to sensitive network infrastructure credentials. The attack vector requires initial access to the database but does not necessitate additional network-based exploitation, making it particularly dangerous in environments where database access is already compromised. The vulnerability affects the integrity and confidentiality of the entire SANnav ecosystem, potentially exposing the underlying storage area network infrastructure to unauthorized access and manipulation.
The flaw aligns with CWE-310, which addresses cryptographic issues, specifically focusing on the improper handling of cryptographic keys within system components. This vulnerability also maps to ATT&CK technique T1552.001, which covers "Unsecured Credentials" through the extraction and misuse of stored passwords and authentication tokens. The attack chain typically involves initial compromise of database access followed by key extraction from supportsave files and subsequent credential decryption, creating a multi-stage exploitation process that can lead to complete system compromise.
Mitigation strategies should focus on implementing strict access controls around database and supportsave file access, ensuring that encryption keys are never written to persistent storage under error conditions. Organizations should establish robust key management practices that separate encryption keys from the systems where they are used, implementing hardware security modules or secure key storage solutions. Regular monitoring of supportsave file creation and access patterns should be implemented to detect anomalous behavior that may indicate exploitation attempts. Additionally, system administrators should ensure that all installation and upgrade processes are performed under controlled conditions with proper error handling that prevents key exposure, and that regular security audits verify the absence of exposed encryption material in system support files.
