The vulnerability identified as CVE-2019-7566 affects CSZ CMS version 1.1.8 and represents a cross-site request forgery flaw that specifically targets the administrative user management functionality. This vulnerability resides within the path admin/users/new/add which allows unauthorized users to manipulate the content management system's user creation process. The flaw enables attackers to execute malicious requests on behalf of authenticated administrators without their knowledge or consent, potentially leading to unauthorized user account creation and privilege escalation within the CMS environment.
This CSRF vulnerability stems from the absence of proper anti-forgery tokens or validation mechanisms in the administrative user creation endpoint. The flaw allows an attacker to craft malicious web pages or emails that, when visited by an authenticated administrator, automatically submit requests to create new user accounts within the CMS. The vulnerability is particularly dangerous because it targets the administrative interface where users can create new accounts with elevated privileges. According to CWE classification, this represents a weakness in the implementation of CSRF protection mechanisms, specifically CWE-352 which addresses Cross-Site Request Forgery vulnerabilities. The attack pattern aligns with ATT&CK technique T1078 which covers valid accounts and T1548.001 which covers abuse of cloud platforms, as compromised administrative accounts can be leveraged for further system compromise.
The operational impact of this vulnerability extends beyond simple unauthorized user creation. An attacker could potentially create administrator accounts with full privileges, leading to complete system compromise and unauthorized access to sensitive data. The vulnerability affects the integrity and availability of the CMS by allowing unauthorized modifications to user access controls. Additionally, the presence of such a flaw indicates poor security hygiene in the application's development lifecycle, potentially exposing other administrative functions to similar attacks. The impact is amplified in environments where administrators frequently access the CMS from shared or public computers, as the CSRF attack can be executed through social engineering techniques.
Mitigation strategies for this vulnerability should focus on implementing robust CSRF protection mechanisms throughout the application's administrative interface. The primary recommendation involves implementing anti-forgery tokens that are validated on every administrative request, ensuring that requests originate from legitimate sources within the application. The CMS should enforce strict session management controls and implement proper input validation for all administrative endpoints. Organizations should also consider implementing additional security layers such as multi-factor authentication for administrative accounts and regular security audits of web applications. According to industry best practices and NIST guidelines for web application security, all administrative interfaces should be protected against CSRF attacks through comprehensive token-based validation mechanisms. The vulnerability also highlights the importance of regular security updates and patch management processes, as this flaw could have been prevented through proper security testing and validation during the software development lifecycle.
