The vulnerability identified as CVE-2010-2139 represents a critical SQL injection flaw within the Multishop content management system, specifically affecting the pages.php script. This vulnerability resides in the handling of user-supplied input through the id parameter, creating a pathway for malicious actors to manipulate database queries and potentially gain unauthorized access to sensitive information. The issue stems from inadequate input validation and sanitization mechanisms within the application's database interaction layer, allowing attackers to inject malicious SQL code that executes with the privileges of the web application's database user.
The technical exploitation of this vulnerability occurs when an attacker submits a crafted id parameter value that contains malicious SQL payload to the pages.php endpoint. The application fails to properly escape or validate this input before incorporating it into database queries, enabling the execution of arbitrary SQL commands. This flaw falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection vulnerabilities where untrusted data is directly included in SQL commands without proper sanitization. The vulnerability's impact extends beyond simple data retrieval, as successful exploitation could allow attackers to extract, modify, or delete database contents, potentially leading to complete system compromise.
From an operational perspective, this vulnerability presents significant risks to organizations utilizing Multishop CMS, particularly those handling sensitive customer data or transactional information. The remote nature of the attack means that threat actors can exploit this flaw from anywhere on the internet without requiring physical access to the target system. Attackers can leverage this vulnerability to perform data exfiltration, escalate privileges within the database, or even establish persistent access through database backdoors. The attack surface is broad as any user interaction with the pages.php script could potentially be exploited, making this vulnerability particularly dangerous in environments with multiple user roles or public-facing web applications.
Security practitioners should implement multiple layers of mitigation strategies to address this vulnerability effectively. The primary defense involves implementing proper input validation and parameterized queries to prevent malicious SQL code from being executed. Applications should utilize prepared statements or stored procedures that separate SQL command structure from data, ensuring that user input is never directly incorporated into SQL queries. Additionally, implementing web application firewalls and input sanitization mechanisms can provide additional protection layers. Regular security audits and code reviews focusing on database interaction patterns should be conducted to identify similar vulnerabilities within the application codebase. Organizations should also consider implementing principle of least privilege for database accounts, ensuring that web applications only have access to the minimum database permissions required for their operation. The vulnerability demonstrates the critical importance of input validation and proper database security practices as outlined in industry standards such as the OWASP Top Ten and NIST cybersecurity frameworks.
