The CVE-2010-4400 vulnerability represents a critical SQL injection flaw in DynPG CMS version 4.2.0 that exposes the application to remote code execution attacks through improper input validation. This vulnerability specifically affects the _rights.php script which handles user rights management functionality within the content management system. The flaw occurs when the application fails to properly sanitize user-supplied input before incorporating it into SQL query constructs, creating an exploitable pathway for malicious actors to manipulate database operations.
The technical implementation of this vulnerability stems from the application's handling of the giveRights_UserId parameter, which is processed without adequate input validation or parameterization. When an attacker submits malicious input through this parameter, the CMS directly incorporates the unsanitized data into SQL commands without proper escaping or sanitization mechanisms. This primitive approach to input handling aligns with CWE-89, which categorizes SQL injection vulnerabilities as a fundamental flaw in application security where untrusted data is concatenated into SQL commands without proper validation. The vulnerability exists at the application layer where user input transitions directly into database operations without appropriate security controls.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and unauthorized access to sensitive information. Remote attackers can leverage this flaw to execute arbitrary SQL commands against the underlying database, potentially gaining read access to user credentials, content management data, and other sensitive system information. The attack surface is particularly concerning as it affects core administrative functionality, allowing unauthorized users to escalate privileges and assume control over the CMS environment. This vulnerability directly maps to ATT&CK technique T1071.004 for Application Layer Protocol: DNS and T1213.002 for Data from Information Repositories, as it enables unauthorized access to database resources through application layer exploitation.
Mitigation strategies for CVE-2010-4400 should prioritize immediate patching of the DynPG CMS to the latest secure version that addresses the SQL injection vulnerability. Organizations should implement proper input validation and parameterized queries throughout the application to prevent similar issues in the future. The implementation of web application firewalls and database activity monitoring can provide additional layers of protection against exploitation attempts. Security teams should also conduct comprehensive code reviews focusing on database interaction patterns and ensure that all user-supplied inputs undergo rigorous sanitization before being processed by database engines. Additionally, implementing principle of least privilege access controls and regular security assessments can help reduce the potential impact of such vulnerabilities in the event of future exploitation attempts.
