Disk exhaustion via unbounded audit log entries
Published Jul 9, 2026 · Updated Jul 9, 2026
Resource-exhaustion DoS in Nozomi Networks Guardian and Central Management Console before 26.2.0 allows remote attackers to fill disk space. The audit logger records attacker-supplied request data without a size limit, allowing oversized entries to consume all available storage. No authentication is required at the web management interface; exhausted storage can render the appliance inoperable.
