Critical · published August 16, 2019
CVSS calls it critical at 9.8. It is confirmed in active exploitation. It sits in the 100.0th percentile for exploit probability.
🚨 A command injection vulnerability lurks in Webmin <=1.920, hiding in the password-change process — and it’s as dangerous as it sounds! 🔥 Think of this like a restaurant where a disgruntled customer can sneak a note to the chef through the order window and request something wild, like adding extra ingredients that shouldn’t be there. This vulnerability lets attackers slip commands into the server without anyone noticing! This flaw could allow an attacker to execute arbitrary commands on the server, leading to absolutely devastating consequences, like data breaches or service disruptions. If exploited, they could take complete control over the server, putting sensitive information at serious risk! 😱
Think of this like a restaurant where a disgruntled customer can sneak a note to the chef through the order window and request something wild, like adding extra ingredients that shouldn’t be there. This vulnerability lets attackers slip commands into the server without anyone noticing! The command injection vulnerability arises from the 'old' parameter in the password_change.cgi script, which fails to properly sanitize input, allowing attackers to execute malicious commands remotely.
This flaw could allow an attacker to execute arbitrary commands on the server, leading to absolutely devastating consequences, like data breaches or service disruptions. If exploited, they could take complete control over the server, putting sensitive information at serious risk! 😱 Update Webmin to version 1.921 or later immediately to patch this vulnerability. Additionally, conduct a review of server access logs and configurations to ensure no unauthorized changes have been made. Implement web application firewalls to help catch any malicious input attempts in the future. You've got this! By updating and tightening security, you can shield your server from this threat and maintain your superhero status in the cybersecurity world! 🦸♂️
