The vulnerability identified as CVE-2006-3140 represents a critical SQL injection flaw within the openCI content management system version 1.0 BETA 0.20.1 and earlier releases. This vulnerability exists in the index.php file and specifically targets the id parameter which is susceptible to malicious input manipulation. The flaw allows remote attackers to execute arbitrary SQL commands against the underlying database system, potentially leading to complete system compromise and unauthorized data access.
This vulnerability falls under the CWE-89 category of SQL Injection, which is classified as a common weakness in software applications that fail to properly sanitize user input before incorporating it into database queries. The openCI system fails to implement proper input validation and parameterized query mechanisms, allowing attackers to inject malicious SQL code through the id parameter. When the application processes user input without adequate sanitization, it creates an environment where attackers can manipulate database queries to extract, modify, or delete sensitive information.
The operational impact of this vulnerability is severe and multifaceted. Remote attackers can leverage this flaw to gain unauthorized access to database contents, potentially accessing user credentials, personal information, and other sensitive data stored within the system. The vulnerability enables attackers to perform unauthorized database operations including data retrieval, modification, and deletion, which can result in complete system compromise. Additionally, this vulnerability may allow attackers to escalate privileges, execute arbitrary code on the server, or even establish persistent backdoors within the compromised system.
From an attack perspective, this vulnerability aligns with the MITRE ATT&CK framework under the T1190 technique for exploitation of remote services and T1078 for valid accounts usage. The attack vector is straightforward and can be executed remotely without requiring special privileges or access to the system. Attackers typically exploit such vulnerabilities by crafting malicious SQL payloads that bypass authentication mechanisms and manipulate database queries to achieve their objectives. The vulnerability's presence in a widely used content management system makes it particularly attractive to automated attack tools and malicious actors seeking to compromise web applications.
The recommended mitigations for this vulnerability include immediate patching of the openCI system to the latest stable release that contains proper input validation and sanitization mechanisms. Organizations should implement proper parameterized queries and prepared statements to prevent SQL injection attacks from occurring. Input validation should be enforced at multiple levels including client-side and server-side to ensure that all user-supplied data is properly sanitized before being processed. Additionally, implementing proper access controls, database user permissions, and regular security audits can help reduce the potential impact of such vulnerabilities. The system should also be configured with appropriate logging and monitoring capabilities to detect suspicious database access patterns that may indicate exploitation attempts.
