The vulnerability identified as CVE-2014-2311 represents a critical sql injection flaw within the MODX content management system, specifically affecting versions prior to 2.2.13. This vulnerability resides in the modx.class.php file which serves as a core component of the MODX Revolution platform. The flaw enables remote attackers to inject malicious sql commands through unspecified vectors, potentially compromising the entire database infrastructure. The vulnerability classification aligns with CWE-89 which specifically addresses sql injection weaknesses in software applications. This particular vulnerability demonstrates how insufficient input validation and improper sql query construction can create pathways for unauthorized database access and manipulation.
The technical implementation of this vulnerability stems from inadequate sanitization of user inputs within the modx.class.php file. Attackers can exploit this weakness by crafting malicious payloads that bypass normal input validation mechanisms and inject arbitrary sql commands into the application's database queries. The unspecified vectors suggest that multiple entry points within the system could be compromised, making the vulnerability particularly dangerous as it may not be easily predictable or isolated. This type of vulnerability typically occurs when developers fail to properly escape or parameterize user inputs before incorporating them into sql statements, creating opportunities for attackers to manipulate the intended execution flow of database operations.
The operational impact of CVE-2014-2311 extends far beyond simple data theft, as successful exploitation could enable attackers to perform complete database compromise including data modification, deletion, or unauthorized access to sensitive information. The vulnerability affects the fundamental integrity of the content management system, potentially allowing attackers to escalate privileges, access administrative functions, or even execute arbitrary code on the underlying server. Organizations using affected MODX versions face significant risk of data breaches, service disruption, and potential regulatory compliance violations. The attack surface is particularly concerning given that this vulnerability operates at the database layer, meaning that even if web application defenses are bypassed, the underlying database remains at risk. This vulnerability type is categorized under the attack technique of command injection within the MITRE ATT&CK framework, specifically targeting the database layer and potentially enabling lateral movement within compromised environments.
Mitigation strategies for this vulnerability require immediate patching of affected MODX installations to version 2.2.13 or later, which contains the necessary security fixes. Organizations should also implement comprehensive input validation mechanisms, employ parameterized queries, and conduct regular security assessments of their web applications. Additional defensive measures include implementing web application firewalls, monitoring database access logs for suspicious activities, and establishing proper network segmentation to limit potential damage from successful exploitation attempts. Security teams should also consider implementing database activity monitoring solutions and regular vulnerability scanning to identify similar weaknesses in other applications within their infrastructure. The remediation process should include thorough testing of patched environments to ensure that the vulnerability has been properly addressed without introducing new issues.
