Exploitability

CWE

KEV
KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is a SQL injection flaw in cPanel's EmailTrack component. An authenticated user with mail privileges can exploit it to create arbitrary files on the server. This could lead to remote code execution as the root user, giving full server control.

Detection Guidance

Check for unauthorized file creation in cPanel's EmailTrack directories. Review SQL query logs for suspicious patterns in mail-related queries. Monitor for unexpected root-level processes originating from cPanel accounts.

Impact Analysis

If exploited, an attacker could gain root access to the server, allowing them to execute any command, steal data, install malware, or disrupt services. This could lead to complete system compromise and data breaches.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations may face legal penalties, fines, and reputational damage.

Mitigation Strategies

Update cPanel/WHM to the latest patched versions immediately: v11.110.0.143, v11.134.0.55, v11.136.0.39, v11.138.0.4, or WP2 v11.138.1.9. Disable mail-related privileges for untrusted accounts until patched.
