The vulnerability identified as CVE-2018-11535 resides within the SITEMAKIN SLAC (Site Login and Access Control) version 1.0 software, representing a critical security flaw that exposes the application to unauthorized data access and system compromise. This issue manifests through improper input validation within the users.php script where the "my_item_search" parameter fails to adequately sanitize user-supplied data before incorporating it into database queries. The vulnerability falls under the category of SQL injection attacks as defined by CWE-89, which specifically addresses improper neutralization of special elements used in SQL commands. The flaw allows malicious actors to manipulate the database query structure by injecting malicious SQL code through the vulnerable parameter, potentially enabling them to extract sensitive information, modify database contents, or even escalate privileges within the affected system.
The technical exploitation of this vulnerability occurs when an attacker submits specially crafted input through the "my_item_search" parameter in the users.php file. This input bypasses the application's security controls and directly influences the SQL query execution process, allowing for unauthorized database access. The vulnerability demonstrates characteristics consistent with CWE-77 and CWE-89 classifications, where user input is improperly handled and directly embedded into database queries without adequate sanitization or parameterization. The attack vector specifically targets the parameter parsing mechanism within the application's user management interface, where the search functionality fails to implement proper input validation techniques. This flaw enables attackers to perform various malicious activities including but not limited to data exfiltration, authentication bypass, and potential system compromise through database manipulation.
The operational impact of CVE-2018-11535 extends beyond simple data theft, as it provides attackers with potential access to sensitive user credentials, personal information, and system configuration details stored within the database. Organizations utilizing this vulnerable version of SLAC software face significant risks including unauthorized access to user accounts, potential data breaches, and possible system infiltration that could lead to broader network compromise. The vulnerability's exploitation can result in complete database exposure, allowing attackers to view, modify, or delete sensitive information while potentially gaining elevated privileges within the application environment. This represents a severe threat to data confidentiality and integrity, particularly in environments where the software manages user access controls and authentication mechanisms. The attack surface is further expanded by the fact that this vulnerability affects the core user management functionality, making it a prime target for exploitation.
Mitigation strategies for CVE-2018-11535 must prioritize immediate remediation through software updates and patches provided by the vendor, as this vulnerability represents a known security flaw that has been addressed in subsequent releases. Organizations should implement proper input validation and parameterized queries to prevent SQL injection attacks, following industry best practices and standards such as those outlined in the OWASP Top Ten and NIST guidelines. The implementation of proper database access controls, including least privilege principles, can limit the damage that could result from successful exploitation. Additionally, network segmentation and monitoring solutions should be deployed to detect and prevent unauthorized access attempts. Organizations must also consider implementing web application firewalls and intrusion detection systems to provide additional layers of protection against SQL injection attacks. Regular security assessments and vulnerability scanning should be conducted to identify similar issues within the application infrastructure and ensure that all security controls remain effective against evolving threats.
