Dockwatch is a software product used for monitoring Docker containers, intended primarily for system administrators and DevOps teams who manage containerized environments. Dockwatch provides a visual interface to monitor container health, system metrics, and alerts for unusual activity, making it an essential tool for ensuring the optimal operation of Docker environments. Its features are designed to enhance productivity by offering real-time monitoring and insights, ensuring rapid detection and resolution of issues. With a user-friendly dashboard, Dockwatch can be easily implemented in various IT environments to manage Docker containers. It supports integration with several other tools and services, providing a comprehensive solution for container management and monitoring.
The OS Command Injection vulnerability present in Dockwatch allows attackers to execute arbitrary commands on the host system. This vulnerability is critical as it does not require authentication and results from improper handling of input data. Exploitation of this vulnerability requires an attacker to seed a session flag due to an incomplete authentication check in the software. The flaw is particularly dangerous because it can be leveraged to gain control over the host system, leading potentially to a full system compromise. Given its critical nature, addressing this vulnerability should be a priority for cybersecurity teams managing environments that utilize Dockwatch.
The technical specifics of the vulnerability involve unauthenticated command injection due to missing exit() after an authentication redirect in the loader.php and unsanitized input in ajax/compose.php. Attackers can manipulate this vulnerability by leveraging an endpoint's parameters, specifically targeting the ajax/compose.php to introduce malicious payloads. This allows arbitrary shell command execution, significantly increasing the risk of host compromise. As remote command injections provide attackers substantial control over the affected systems, it is imperative for users to ascertain their installations are patched to prevent exploitation. The recommended course of action includes reviewing and fixing authentication processes and sanitizing input data.
Potential effects of the exploitation of this vulnerability include unauthorized control over the host, execution of arbitrary commands, data exfiltration, and potentially spreading malware within internal networks. The vulnerability can further lead to compromised server integrity, causing a major security breach affecting both the confidentiality and the integrity of data within the affected host environment. It provides a gateway for attackers to further exploit other weaknesses within an organization's network, leading to escalated privileges or lateral movement.
REFERENCES
- Update Dockwatch to the latest version that patches the authentication and input validation issues.
- Implement input validation and proper sanitation techniques on all user inputs.
- Regularly audit logs and system calls to detect any unauthorized command execution attempts.
- Isolate the application environments to minimize the impact of potential attacks.
- Ensure that exit mechanisms are properly applied after authentication processes to prevent unauthorized access.
