Description Preview
A command injection vulnerability (CWE-78) exists in Roundcube Webmail versions prior to 1.4.4. The vulnerability is located in rcube_image.php, which allows attackers to execute arbitrary code by injecting shell metacharacters into configuration settings for im_convert_path or im_identify_path parameters. This could lead to remote code execution on affected systems.
Overview
The vulnerability affects Roundcube Webmail, a popular open-source webmail solution. The issue stems from insufficient validation of user input in the rcube_image.php file, which handles image processing functionality. An attacker could exploit this vulnerability by manipulating the configuration settings for ImageMagick paths (im_convert_path or im_identify_path), allowing them to inject shell commands that would be executed on the server. This is a serious security issue as it could lead to complete system compromise, data theft, or service disruption.
Remediation
To address this vulnerability, users should upgrade to Roundcube Webmail version 1.4.4 or later. The following versions contain security fixes:
- Version 1.4.4 for the 1.4.x branch
- Version 1.3.11 for the 1.3.x branch
- Version 1.2.10 for the 1.2.x branch
If immediate upgrading is not possible, administrators should:
- Review and validate their ImageMagick path configurations
- Implement additional input validation for these configuration settings
- Consider restricting access to the administrative interfaces
- Monitor systems for suspicious activities that might indicate exploitation attempts
