The vulnerability identified as CVE-2007-0507 represents a critical SQL injection flaw within the Acidfree module for the Drupal content management system. This vulnerability specifically affects versions prior to 4.6.x-1.0 and 4.7.x-1.0 within the 4.7 series, creating a significant security risk for Drupal installations that utilize this module. The flaw occurs in the handling of node titles, which are processed through user input without proper sanitization or validation mechanisms. The vulnerability is classified under CWE-89, which denotes SQL injection vulnerabilities, and aligns with ATT&CK technique T1190, specifically targeting the exploitation of input validation weaknesses in web applications.
The technical nature of this vulnerability stems from the module's failure to properly escape or filter user-supplied data when processing node titles. When authenticated users with the specific privilege level of "create acidfree albums" submit content, their input is directly incorporated into SQL queries without appropriate sanitization. This allows malicious actors to inject arbitrary SQL commands that can be executed against the underlying database. The exploitation requires the attacker to possess valid authentication credentials and the specific user permissions, but once achieved, the impact extends beyond simple data manipulation to potentially full database compromise. The vulnerability demonstrates poor input validation practices and highlights the importance of implementing proper data sanitization techniques in web applications.
The operational impact of this vulnerability is severe as it enables authenticated attackers to execute arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion. Attackers could leverage this vulnerability to extract sensitive information from the database, modify existing records, or even gain administrative access to the system. The requirement for the specific "create acidfree albums" privilege means that the attack vector is somewhat limited compared to fully unauthenticated exploits, but it still represents a significant risk in environments where user privilege management is not properly enforced. The vulnerability affects the integrity and confidentiality of the data stored within the Drupal system, potentially compromising the entire web application infrastructure.
Mitigation strategies for CVE-2007-0507 involve immediate patching of the affected Drupal installations to versions that contain proper input validation and sanitization measures. Organizations should implement the latest security updates for the Acidfree module and ensure that all Drupal core installations are current with security patches. Additionally, administrators should review and restrict user privileges to minimize the attack surface, ensuring that only necessary users possess the "create acidfree albums" permission. Input validation should be implemented at multiple layers including application-level sanitization and database-level query parameterization. The implementation of web application firewalls and intrusion detection systems can provide additional monitoring capabilities to detect and prevent exploitation attempts. Regular security audits and code reviews should be conducted to identify similar vulnerabilities in other modules and ensure proper security practices are maintained throughout the application stack.
