The vulnerability identified as CVE-2018-10364 represents a cross-site scripting flaw within the BigTree CMS platform affecting versions prior to 4.2.22. This security weakness resides within the user management interface where malicious actors can inject malicious scripts through the name or company fields during user registration or profile modification processes. The vulnerability stems from inadequate input validation and output sanitization mechanisms that fail to properly escape or filter user-supplied data before rendering it within web pages. This particular flaw falls under the CWE-79 category of Cross-Site Scripting, specifically representing a stored XSS attack vector where the malicious payload persists in the application's database and executes whenever the affected page is accessed by other users. The attack scenario involves an attacker crafting malicious script code within the vulnerable input fields, which then gets stored in the system and executed in the context of other users' browsers when they view the user management page or related interfaces.
The operational impact of this vulnerability extends beyond simple data theft or session hijacking, as it provides attackers with the capability to execute arbitrary JavaScript code within the context of authenticated user sessions. This could enable attackers to steal session cookies, modify user permissions, access sensitive administrative functions, or redirect users to malicious websites. The vulnerability affects all users who have access to the user management functionality, potentially including administrators who might be tricked into viewing compromised user profiles. Attackers could leverage this vulnerability to escalate privileges, gain unauthorized access to sensitive data, or establish persistent backdoors within the CMS environment. The stored nature of the XSS payload means that the attack can affect multiple users over time without requiring repeated exploitation attempts, making it particularly dangerous for organizations with numerous users or frequent user management activities.
Security professionals should implement comprehensive input validation and output encoding mechanisms to address this vulnerability, ensuring that all user-supplied data undergoes proper sanitization before being stored or rendered in web pages. The recommended remediation involves upgrading to BigTree CMS version 4.2.22 or later, which includes proper input validation and output escaping measures. Organizations should also implement Content Security Policy headers to mitigate the impact of potential XSS attacks, and conduct regular security testing to identify similar vulnerabilities in custom applications or third-party components. According to ATT&CK framework, this vulnerability maps to T1059.007 for script injection techniques and T1531 for credential access through web application vulnerabilities. Additional mitigation strategies include implementing web application firewalls, conducting regular security awareness training for administrators, and establishing proper code review processes to prevent similar input validation issues in custom developed applications. The vulnerability demonstrates the critical importance of proper input sanitization and output encoding practices in web applications, particularly those handling user-generated content in administrative interfaces where the potential for privilege escalation exists.
