This vulnerability exists within the dotCMS content management system where an authenticated administrator can exploit a sql injection flaw in the Content Types interface. The vulnerability specifically targets the _EXT_STRUCTURE_direction parameter which is processed without adequate input sanitization or parameter validation. Attackers with administrative privileges can manipulate this parameter to inject malicious sql commands that will be executed on the underlying database server. The vulnerability affects versions prior to 3.7.2 and 4.x prior to 4.1.1, indicating it was present in multiple major releases of the platform. This represents a critical security flaw as it allows privilege escalation through sql injection attacks that can potentially lead to complete database compromise.
The technical implementation of this vulnerability stems from improper input validation within the content type management functionality. When administrators navigate to the Content Types screen and interact with the structure management features, the _EXT_STRUCTURE_direction parameter is directly incorporated into sql queries without proper escaping or parameterization. This creates an environment where malicious input can alter the intended sql execution flow and inject arbitrary commands. The vulnerability falls under the common weakness enumeration CWE-89 which specifically addresses sql injection flaws. This weakness is classified as a direct code injection vulnerability where user-supplied data is interpreted as sql code rather than data.
The operational impact of this vulnerability is severe as it enables authenticated attackers with administrative privileges to execute arbitrary sql commands on the database server. This can result in data exfiltration, data corruption, privilege escalation, and potentially full system compromise. Attackers could extract sensitive information from the database, modify content types and their associated data structures, or even gain access to other systems if database users have elevated privileges. The vulnerability is particularly dangerous because it requires only administrative authentication, which is typically a high-privilege account with broad access to system functionality. This aligns with the attack pattern described in the attack technique matrix where attackers leverage legitimate administrative accounts to perform malicious activities.
Mitigation strategies for this vulnerability include immediate patching of affected dotCMS installations to versions 3.7.2 or 4.1.1 and later. Organizations should also implement proper input validation and parameterization techniques for all sql queries within the application. The principle of least privilege should be enforced where administrative accounts have minimal necessary permissions and regular access reviews should be conducted. Additionally, web application firewalls and sql injection detection systems should be configured to monitor for suspicious sql patterns. Security monitoring should include logging and alerting on unusual administrative activities, particularly those involving database structure modifications. Regular security assessments and code reviews should be performed to identify similar vulnerabilities in other parts of the application that may be susceptible to similar injection attacks. The vulnerability demonstrates the importance of proper input sanitization and parameterized queries as recommended in secure coding practices and industry standards for preventing sql injection attacks.
