The vulnerability identified as CVE-2018-15894 represents a critical sql injection flaw within the WUZHI CMS 4.1.0 content management system. This vulnerability exists in the administrative pay module at the specific file path /coreframe/app/admin/pay/admin/index.php, where the application fails to properly sanitize user input parameters. The vulnerable parameter is the index.php?m=pay&f=index&v=listing keyValue which allows malicious actors to inject arbitrary sql commands through the v=listing parameter. This type of vulnerability falls under the common weakness enumeration CWE-89 which specifically addresses sql injection flaws in software applications.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious input that gets directly incorporated into sql query statements without proper sanitization or parameterization. The vulnerability is particularly dangerous because it affects the administrative interface of the cms system, potentially allowing attackers to escalate privileges and gain full control over the compromised system. The attack vector leverages the lack of input validation in the keyValue parameter, which is processed directly within the sql query context. According to the attack technique framework, this vulnerability aligns with ATT&CK technique T1078 which covers valid accounts and T1213 which addresses data from information repositories.
The operational impact of this vulnerability extends beyond simple data theft, as it enables attackers to perform unauthorized database operations including data modification, deletion, or extraction. An attacker could potentially access sensitive administrative information, modify user credentials, or even inject malware through database manipulation. The vulnerability affects the integrity and confidentiality of the entire cms system, making it a high-priority security concern for organizations using WUZHI CMS 4.1.0. Organizations may face regulatory compliance issues and potential data breaches if this vulnerability is exploited, particularly in environments where sensitive user data is stored.
Mitigation strategies for CVE-2018-15894 should include immediate patching of the WUZHI CMS to version 4.1.1 or later, which contains the necessary sql injection fixes. Additionally, organizations should implement proper input validation and parameterized queries throughout their applications to prevent similar vulnerabilities. Network segmentation and access controls should be enforced to limit administrative access to only authorized personnel. Regular security audits and penetration testing should be conducted to identify and remediate similar sql injection vulnerabilities in other applications. The implementation of web application firewalls and database activity monitoring can provide additional layers of protection against sql injection attacks targeting this and similar vulnerabilities.
