The vulnerability identified as CVE-2018-15893 represents a critical SQL injection flaw within the WUZHI CMS 4.1.0 content management system. This vulnerability specifically affects the copyfrom.php script located within the admin section of the application's coreframe directory. The flaw manifests when the application processes user input through the index.php?m=core&f=copyfrom&v=listing URL structure, where the keywords parameter becomes a vector for malicious SQL command injection attempts.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the copyfrom.php script. When administrators or authenticated users interact with the copyfrom functionality, the application fails to properly escape or parameterize the keywords parameter before incorporating it into SQL queries. This omission creates a direct pathway for attackers to inject malicious SQL code that can be executed within the database context. The vulnerability is particularly dangerous because it exists within the administrative interface, potentially allowing unauthorized users to escalate privileges or gain full database access.
The operational impact of this vulnerability extends beyond simple data theft or corruption. Attackers exploiting this flaw can manipulate the database to extract sensitive information including user credentials, administrative session data, and potentially sensitive configuration details. The vulnerability also enables attackers to modify or delete content within the CMS, compromise the integrity of the website, and potentially use the compromised system as a foothold for further attacks within the network. Given that this affects the admin interface, successful exploitation could lead to complete system compromise and unauthorized modification of website content.
Security professionals should note this vulnerability aligns with CWE-89 which categorizes SQL injection as a fundamental weakness in application security. The attack surface is particularly concerning as it targets the administrative functionality of the CMS, making it a prime target for attackers seeking persistent access. Organizations should implement immediate mitigations including input validation, parameterized queries, and access controls to prevent exploitation. The vulnerability also maps to ATT&CK technique T1071.004 which covers application layer protocol manipulation and T1046 which involves network service scanning to identify vulnerable systems. Regular security assessments and patch management protocols should be prioritized to address such vulnerabilities in content management systems that handle sensitive data and user information.
