About SaltStack Salt
SaltStack Salt is an open-source configuration management and remote execution software widely used for IT automation, orchestration, and infrastructure management. This powerful tool allows administrators to automate the configuration of servers and other network devices across diverse environments efficiently.
The Vulnerability: CVE-2020-28972
The Medium-severity issue scored at 5.9 involves improper SSL/TLS certificate validation when SaltStack Salt interacts with VMware products, specifically vCenter, vSphere, and ESXi servers. This flaw is located within the 'vmware.py' files, where SSL certificate validation does not consistently occur, potentially exposing users to man-in-the-middle attacks.
Why is this significant?
The communication between SaltStack Salt and VMware technologies relies heavily on secure connections to manage and orchestrate virtual environments effectively. If these communications are intercepted or manipulated through a compromised SSL/TLS certificate, malicious entities could potentially gain unauthorized access to sensitive information or disrupt operations within the virtualized infrastructure.
Who is affected?
This vulnerability affects all users of SaltStack Salt before version 3002.5 who utilize it for managing VMware environments. It is crucial for administrators using this setup to assess their systems and apply the necessary updates to mitigate the potential risks associated with this flaw.
Steps for Mitigation:
1. Update Immediately: Upgrade to SaltStack Salt version 3002.5 or later. This version includes patches that address the SSL/TLS certificate validation issue.
2. Verify SSL/TLS Configurations: Review your SSL/TLS configuration settings to ensure that they enforce proper certificate validation. Pay particular attention to custom configurations or scripts that might bypass standard security protocols.
3. Enhance Monitoring: Increase the monitoring of network traffic, especially those involving connections to VMware platforms to detect any anomalies that could indicate compromised communications.
4. Security Best Practices: Continuously apply security best practices and regular updates across all IT systems to minimize vulnerabilities and enhance overall security posture.
Conclusion
CVE-2020-28972 serves as a critical reminder of the importance of maintaining rigorous security measures when managing virtual environments. By staying ahead of updates and adhering to best practices, administrators can protect their networks from potential threats.
