i-doit CMDB SQL Injection (CVE-2019-25581)

Overview

A critical SQL injection vulnerability, identified as CVE-2019-25581, has been discovered in i-doit CMDB version 1.12. This flaw allows attackers without any login credentials to execute arbitrary SQL commands on the underlying database. The vulnerability is located in the handling of the objGroupID parameter, which fails to properly validate or sanitize user input.

Vulnerability Details

In simple terms, SQL injection occurs when an application unintentionally allows user-supplied data to be interpreted as part of a database command. In this specific case, an unauthenticated attacker can send a specially crafted HTTP GET request to the affected i-doit system. By manipulating the objGroupID parameter in this request with malicious SQL code, the attacker can trick the database into executing commands it was never intended to run.

Potential Impact

The impact of this vulnerability is severe. Successful exploitation allows an attacker to:

• Extract sensitive information directly from the database, including administrative usernames, passwords (potentially hashed), database names, and version details.
• Potentially modify, delete, or exfiltrate any data within the CMDB, which often contains critical IT infrastructure information.
• Use the database server as a foothold for further attacks within the network.

This can lead to a full compromise of the CMDB’s integrity and confidentiality, facilitating data breaches and operational disruption. For insights into real-world data breaches, you can review historical incidents at breach reports.

Remediation and Mitigation

Immediate action is required to protect affected systems.

1. Patch or Upgrade: The primary solution is to upgrade i-doit CMDB to a version that includes a fix for this vulnerability. Consult the official i-doit vendor advisories and release notes for the appropriate patched version.
2. Input Validation and Sanitization: Ensure all user inputs, especially parameters like objGroupID, are rigorously validated and sanitized. Use prepared statements with parameterized queries, which is the most effective defense against SQL injection.
3. Network Controls: As a temporary mitigation, restrict network access to the i-doit web interface to only trusted IP addresses (e.g., internal management networks) using firewall rules. This does not fix the flaw but can reduce the attack surface.
4. Monitoring: Review web server and database logs for unusual SQL error messages or suspicious query patterns originating from unauthenticated sessions.

Staying informed about such vulnerabilities is crucial for maintaining security. For the latest updates on cybersecurity threats, follow security news. Organizations using i-doit CMDB 1.12 should treat this vulnerability as high priority and apply fixes without delay.
