The vulnerability identified as CVE-2018-18755 affects the K-iwi Framework version 1775 and represents a critical SQL injection flaw that compromises the integrity of database operations within the administrative interface. This vulnerability specifically targets two distinct parameter injection points within the framework's user management functionality, creating pathways for malicious actors to execute unauthorized database commands and potentially gain complete control over the underlying data infrastructure.
The technical exploitation of this vulnerability occurs through the manipulation of two specific parameters within the framework's administrative endpoints. The first injection vector targets the user_group_id parameter within the admin/user/group/update endpoint, while the second vector targets the user_id parameter within the admin/user/user/update endpoint. Both parameters lack proper input validation and sanitization mechanisms, allowing attackers to inject malicious SQL code that gets executed within the database context. This flaw falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection vulnerabilities that occur when untrusted data is incorporated into database queries without proper sanitization.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to perform a wide range of malicious activities including but not limited to unauthorized data access, data modification, data deletion, and potentially privilege escalation within the database system. Successful exploitation could result in complete database compromise, leading to unauthorized access to sensitive user information, administrative credentials, and potentially the entire application infrastructure. The vulnerability's presence in the framework's administrative components makes it particularly dangerous as it could allow attackers to manipulate user permissions, create new administrative accounts, or completely destroy user data.
Organizations utilizing K-iwi Framework version 1775 should immediately implement comprehensive mitigations to address this vulnerability. The primary defense mechanism involves implementing strict input validation and parameterized queries throughout the affected endpoints, ensuring that all user-supplied data is properly sanitized before being incorporated into database operations. Additionally, implementing proper access controls and privilege separation within the administrative interface can limit the potential damage from successful exploitation attempts. The mitigation strategy should also include regular security auditing of all database interactions and the implementation of web application firewalls to detect and block suspicious SQL injection patterns. According to ATT&CK framework methodology, this vulnerability aligns with techniques categorized under T1071.004 for Application Layer Protocol and T1046 for Network Service Scanning, as exploitation typically involves systematic attempts to identify and exploit database interface endpoints. Organizations should also consider implementing database activity monitoring solutions that can detect anomalous query patterns indicative of SQL injection attempts, providing additional layers of defense beyond traditional perimeter security measures.
