Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
An organization's Webmin installations contain a critical vulnerability that allows for unauthenticated remote command execution. This presents a significant risk of unauthorized access and control over affected systems. The issue lies within the `password_change.cgi` script, where a parameter is susceptible to command injection. This could allow attackers to execute arbitrary commands on the server, potentially leading to data breaches, system compromise, or further network intrusion.
- Find all Webmin assets.
- Reduce exposure or isolate affected assets.
- Apply vendor updates and verify the fix.
