Description Preview

CloudPanel v2.2.2 contains a path traversal vulnerability (CWE-22) that allows attackers to navigate outside of restricted directories. This vulnerability can be exploited to access files and directories that are stored outside the intended directory structure, potentially leading to privilege escalation and unauthorized access to sensitive information.

Overview

CloudPanel v2.2.2 is vulnerable to a path traversal attack that could allow attackers to access files outside the intended directory structure. The vulnerability exists because the application does not properly validate user-supplied input that contains directory traversal sequences (such as "../"). By exploiting this vulnerability, an attacker could potentially escalate privileges and gain unauthorized access to sensitive system files. This vulnerability is particularly concerning as it could allow authenticated users to break out of their restricted environment and access files they should not have permission to view or modify.

Remediation

To remediate this vulnerability, users should:

  1. Update CloudPanel to the latest version available from the official website. According to the changelog, versions after 2.2.2 have addressed this security issue.
  2. Implement proper input validation to reject or sanitize file paths containing directory traversal sequences.
  3. Configure web servers to use proper access controls and file system permissions.
  4. Consider implementing a web application firewall (WAF) that can detect and block path traversal attempts.
  5. Follow the principle of least privilege for file system access permissions.
