CVE-2026-14443 in SANnav
Summary
by MITRE • 09/25/2026
Incomplete log sanitization during bulk IPsec policy collection in Brocade SANnav versions before 3.0.1a permit extension switch pre-shared keys to be written to system logs. Individuals with read access to container logs or support archives can obtain these keys, leading to the potential compromise of encrypted network tunnels.

The vulnerability identified in Brocade SANnav prior to version 3.0.1a represents a critical failure in input sanitization and secure logging practices within the bulk Internet Protocol Security policy collection mechanism. This flaw specifically allows pre-shared keys, which are essential for establishing authenticated IPsec tunnels between extension switches, to be written directly into system log files without proper masking or encryption. In enterprise storage area network environments, these pre-shared keys serve as a primary authentication factor for securing data in transit across potentially untrusted networks. The presence of these secrets in plaintext within logs creates a significant attack vector that undermines the confidentiality and integrity guarantees provided by IPsec protocols.
From a technical perspective, this issue stems from an incomplete sanitization process during the bulk processing of policy configurations. When administrators or automated systems submit multiple IPsec policies for deployment, the application fails to strip sensitive credential data before persisting log entries related to these operations. This behavior is consistent with CWE-532, which classifies information exposure through log files as a distinct category of security weakness. The vulnerability does not require complex exploitation techniques; rather, it relies on the attacker gaining access to the underlying infrastructure where logs are stored or archived.
The operational impact of this flaw is severe due to the nature of pre-shared keys in IPsec implementations. Once an adversary obtains these keys through read access to container logs or support archives, they can perform a man-in-the-middle attack against existing encrypted tunnels. By possessing valid credentials that match those configured on the extension switches, the attacker can authenticate themselves as a legitimate peer device. This allows for the decryption of sensitive storage traffic, interception of management commands, and potential lateral movement within the SAN environment. The compromise extends beyond immediate data theft to include long-term risks where historical logs may be retained for extended periods, increasing the window of opportunity for exploitation even after initial remediation efforts have begun if old archives are not purged securely.
This vulnerability aligns with MITRE ATT&CK technique T1507, which involves Dynamic Resolution or Domain Fronting in some contexts but more accurately maps to T1602, specifically sub-technique 1602.002 for Data from Configuration Repositories if logs are considered part of the configuration state, or more directly T1005, Data from Local System Access, as it involves reading local log files. The attack path typically begins with privilege escalation to a level that permits access to container runtime environments or support bundle generation tools. Once inside this context, the attacker queries system logs for keywords related to IPsec policies and extracts the plaintext pre-shared keys.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. The primary solution is to upgrade Brocade SANnav to version 3.0.1a or later, where the developers have addressed this sanitization flaw by ensuring that sensitive fields such as pre-shared keys are masked or omitted from log outputs entirely. In addition to upgrading, organizations should implement strict access controls around log storage systems and support archive generation tools to limit read privileges to only those personnel who absolutely require it for operational troubleshooting. It is also recommended to rotate all affected IPsec pre-shared keys immediately upon patching the system to invalidate any credentials that may have been exfiltrated during the period of vulnerability exposure. Furthermore, implementing centralized log management solutions with built-in sensitive data detection can help identify and redact such information in real-time across broader infrastructure deployments.
