CVE-2026-82369
HighCVSS 8.6Summary
Insufficient input sanitization of shell metacharacters in the Brocade SANnav CLI scripting component permits authenticated users to break out of restricted execution contexts on managed switches. An attacker with command execution permissions can run unauthorized shell commands across target fabric switches, bypassing command allow-lists and obtaining full administrative switch access. This affects all Brocade SANnav versions before 3.0.1a.
Risk Assessment
Obtaining full administrative access to switches could lead to network integrity compromise and traffic interception.
Recommendation
Upgrade Brocade SANnav to version 3.0.1a or later, and restrict command execution permissions for users.
Other vulnerabilities in Brocade SANnav
See all- CVE-2026-82370High
Unauthenticated remote command injection in the Brocade SANnav orchestrator HTTP service allows network-adjacent attackers to execute arbitrary administrative switch CLI commands and issue container management instructions. Affects versions before 3.0.1a.
- CVE-2026-82368High
In Brocade SANnav versions before 3.0.1a, insecure access controls on internal service ports allow local, non-administrative host users to communicate directly with backend management services. A local attacker can leverage this exposed access to transmit commands to connected Fabric OS switches under the security context of the SANnav management user.
