The CVE-2008-4772 vulnerability represents a critical sql injection flaw within QuestCMS version 1.0.0, specifically located in the main/main.php file. This vulnerability manifests through the obj parameter which fails to properly sanitize user input before incorporating it into sql query constructions. The flaw allows remote attackers to manipulate the application's database interactions by injecting malicious sql commands through the vulnerable parameter. The vulnerability directly impacts the application's data integrity and confidentiality by enabling unauthorized database access and manipulation.
This security weakness stems from inadequate input validation and improper sql query construction practices within the QuestCMS framework. The obj parameter in main.php accepts user-supplied data without sufficient sanitization or parameterization, creating an environment where malicious sql payloads can be executed with the privileges of the web application's database user. The vulnerability is classified as a classic sql injection attack vector that operates by appending malicious sql code to the legitimate parameter value, thereby bypassing normal application security controls and database access restrictions.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete database compromise and potential system infiltration. Remote attackers can leverage this flaw to extract sensitive information including user credentials, personal data, and system configurations. The vulnerability also permits attackers to modify or delete database records, potentially leading to data corruption, service disruption, and unauthorized access to administrative functions. Additionally, successful exploitation could enable attackers to escalate privileges and establish persistent access to the affected system.
Mitigation strategies for CVE-2008-4772 should focus on implementing proper input validation and parameterized sql queries throughout the QuestCMS application. The recommended approach involves sanitizing all user inputs including the obj parameter through proper escaping techniques or implementing prepared statements with parameter binding to prevent sql injection. Organizations should also apply the latest security patches provided by QuestCMS developers and consider implementing web application firewalls to detect and block malicious sql injection attempts. This vulnerability aligns with CWE-89 sql injection weakness and corresponds to attack techniques categorized under the ATT&CK framework's data manipulation and credential access tactics. The remediation process should include comprehensive code review to identify similar vulnerabilities in other application components and establish secure coding practices to prevent future occurrences of such flaws.
