An attacker with administrative privileges can remotely supply a crafted update bundle that, when installed, causes arbitrary commands to be executed with root privileges, allowing the attacker to read or modify sensitive data, change the appliance configuration, or shut down the appliance.\n\n## Affected\n\n- `Guardian < 26.4.0`\n- `CMC < 26.4.0`\n\n## Remediation\n\nUpgrade to v26.4.0 or later.\n\n### Workarounds\n\nUse internal firewall features to limit access to the web management interface.\nReview all accounts with administrative privileges and delete unnecessary ones.\nInstall update bundles only when they come from trusted Nozomi Networks sources.","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":39.6,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
