CVE-2026-82371: Plaintext exposure of sensitive authentication data in SANnav discovery service log files

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Brocade SANnav 3.0.1a.

Low priority for now. Upgrade to Brocade SANnav 3.0.1a or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Plaintext exposure of sensitive authentication data in Brocade SANnav discovery service log files enables individuals with file read access to retrieve administrative switch credentials and active session tokens. An attacker with access to system logs or support bundles can leverage exposed authentication details to compromise managed network infrastructure and access active application sessions. This vulnerability affects Brocade SANnav versions before 3.0.1a.
