CVE-2019-25582: I-doit Information Disclosure Flaw

CVE-2019-25582 Overview

CVE-2019-25582 is an arbitrary file download vulnerability affecting i-doit CMDB version 1.12. This flaw allows authenticated attackers to download sensitive files from the server by manipulating the file parameter in index.php. By crafting malicious GET requests with file_manager=image and supplying arbitrary file paths, attackers can retrieve configuration files containing database credentials, API keys, and other sensitive system data.

Critical Impact

Authenticated attackers can exfiltrate sensitive configuration files including src/config.inc.php, potentially exposing database credentials, encryption keys, and other critical system information that could lead to full system compromise.

Affected Products

• i-doit CMDB version 1.12

Technical Details for CVE-2019-25582

Vulnerability Analysis

This arbitrary file download vulnerability exists due to improper input validation in the file manager functionality of i-doit CMDB. The application fails to properly sanitize user-supplied file paths when processing requests through the index.php endpoint. When an authenticated user sends a specially crafted request with the file_manager=image parameter, the application directly uses the supplied file path without adequate validation, allowing directory traversal sequences to access files outside the intended directory.

The vulnerability enables attackers to read any file on the server that the web application has permissions to access. Configuration files such as src/config.inc.php are particularly valuable targets as they typically contain database connection strings, authentication credentials, and application secrets.

Root Cause

The root cause of CVE-2019-25582 is insufficient input validation and path traversal protection in the file manager component. The application accepts arbitrary file paths through the request parameters without properly validating that the requested file resides within an authorized directory. This lack of proper input sanitization allows attackers to use directory traversal techniques (e.g., ../) to escape the intended file access boundaries and retrieve sensitive files from anywhere on the filesystem.

Attack Vector

The attack vector is network-based and requires authenticated access to the i-doit CMDB application. An attacker with valid credentials can exploit this vulnerability by sending crafted HTTP GET requests to the index.php endpoint.

The exploitation flow involves:

1. Authenticating to the i-doit CMDB application with valid credentials
2. Sending a GET request to index.php with the file_manager=image parameter
3. Providing a malicious file path (e.g., src/config.inc.php) as the file parameter
4. The server responds with the contents of the requested file

Detection Methods for CVE-2019-25582

Indicators of Compromise

• Unusual GET requests to index.php containing file_manager=image parameter with suspicious file paths
• Access attempts to configuration files such as config.inc.php, .htaccess, or system files like /etc/passwd
• HTTP requests containing directory traversal sequences (../) in the file parameter
• Abnormal authenticated user activity accessing file manager endpoints repeatedly

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block requests containing directory traversal patterns in file parameters
• Monitor web server access logs for requests to index.php with file_manager=image and unusual file path values
• Configure intrusion detection systems (IDS) to alert on path traversal attempts targeting known sensitive file locations
• Establish baseline metrics for file manager access patterns and alert on deviations

Monitoring Recommendations

• Enable verbose logging for the i-doit application to capture all file access requests with full parameter details
• Set up real-time alerting for any access attempts to sensitive configuration files through web interfaces
• Review authentication logs to identify potentially compromised accounts being used to exploit this vulnerability
• Implement file integrity monitoring on critical configuration files to detect unauthorized access

How to Mitigate CVE-2019-25582

Immediate Actions Required

• Restrict access to the i-doit CMDB application to trusted users and networks only
• Implement network segmentation to limit exposure of the vulnerable application
• Review and rotate any credentials stored in configuration files that may have been compromised
• Apply web application firewall rules to block requests containing path traversal sequences

Patch Information

Organizations using i-doit CMDB version 1.12 should upgrade to a patched version that addresses this arbitrary file download vulnerability. Consult the official i-doit website for the latest security updates and upgrade guidance. Review the VulnCheck Advisory for additional remediation recommendations.

Workarounds

• Implement strict input validation at the web server or reverse proxy level to block requests with suspicious file paths
• Use .htaccess or server configuration to deny direct access to sensitive configuration files
• Restrict file system permissions for the web server process to limit accessible files
• Consider implementing additional authentication layers or IP-based access controls for the file manager functionality

# Example Apache configuration to block access to sensitive files
<FilesMatch "\.(inc\.php|htaccess|htpasswd|config|conf)$">
    Require all denied
</FilesMatch>

# Example mod_rewrite rule to block path traversal attempts
RewriteEngine On
RewriteCond %{QUERY_STRING} (\.\./) [NC,OR]
RewriteCond %{QUERY_STRING} (config\.inc\.php) [NC]
RewriteRule .* - [F,L]
