The vulnerability CVE-2018-11528 affects WUZHI CMS version 4.1.0 and represents a critical SQL injection flaw within the application's API endpoint. This vulnerability exists in the api/sms_check.php file where the param parameter is not properly sanitized before being incorporated into database queries. The flaw allows remote attackers to execute arbitrary SQL commands by manipulating the URI parameter, potentially leading to complete database compromise and unauthorized access to sensitive information. The vulnerability is classified as CWE-89 according to the Common Weakness Enumeration catalog, which specifically addresses improper neutralization of special elements used in SQL commands.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious URI request containing specially formatted SQL payload within the param parameter of the sms_check.php endpoint. The application fails to implement proper input validation or parameterized queries, allowing the injected SQL code to be executed directly against the underlying database system. This creates a pathway for attackers to extract, modify, or delete database contents, potentially gaining administrative privileges within the CMS environment. The vulnerability demonstrates poor input sanitization practices and violates fundamental secure coding principles that are essential for preventing SQL injection attacks.
The operational impact of this vulnerability is severe as it provides attackers with unrestricted access to the database backend of affected WUZHI CMS installations. An attacker could leverage this vulnerability to steal user credentials, personal information, and other sensitive data stored within the database. Additionally, the compromised system could be used as a staging ground for further attacks, including lateral movement within the network infrastructure or deployment of malicious payloads. The vulnerability affects the integrity and confidentiality of the entire content management system, potentially leading to complete system compromise and data breach incidents that could result in regulatory penalties and significant financial losses.
Mitigation strategies for CVE-2018-11528 should include immediate patching of the WUZHI CMS to version 4.1.1 or later where the SQL injection vulnerability has been addressed. Organizations should implement proper input validation and parameterized queries throughout the application codebase to prevent similar vulnerabilities from occurring in the future. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and filtering malicious requests targeting the vulnerable endpoint. According to ATT&CK framework category T1190, this vulnerability aligns with the technique of exploiting vulnerabilities in software applications, making it critical for organizations to maintain up-to-date security patches and conduct regular vulnerability assessments to identify and remediate similar weaknesses across their infrastructure.
