The vulnerability identified as CVE-2019-7567 represents a cross-site scripting flaw within the Waimai Super Cms version 20150505, specifically affecting the admin.php?m=Member&a=adminaddsave endpoint. This issue arises from inadequate input validation and output sanitization mechanisms that fail to properly escape or filter user-supplied data before processing it within the application's administrative interface. The vulnerability manifests when administrative users interact with the member management functionality, particularly during the addition of new members through the administrative panel.
The technical exploitation of this vulnerability occurs through the manipulation of the username or password parameters within the specified administrative endpoint. When an attacker crafts malicious input containing script tags or other executable code within these parameters, the application fails to properly sanitize the data before storing or displaying it. This allows an attacker to inject malicious scripts that execute in the context of other users' browsers who view the affected administrative records. The vulnerability is classified as a classic reflected cross-site scripting issue where the malicious payload is reflected back to the user through the application's response without proper encoding or sanitization.
The operational impact of this vulnerability extends beyond simple data corruption or display issues, as it provides attackers with the capability to escalate privileges within the administrative interface. An attacker could potentially gain unauthorized access to sensitive administrative functions, modify user permissions, or even execute arbitrary commands within the context of the web application. The vulnerability affects the integrity and confidentiality of the administrative user data, potentially leading to complete system compromise if combined with other exploitation techniques. The persistence of this vulnerability in a widely used content management system increases the potential attack surface significantly.
Security professionals should note that this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications. The weakness demonstrates poor input validation practices and inadequate output encoding mechanisms that are fundamental requirements for secure web application development. From an attacker perspective, this vulnerability maps to ATT&CK technique T1059.007 for scripting and T1566 for credential access, as it enables unauthorized users to manipulate administrative functions and potentially extract sensitive information. Organizations should implement proper parameter validation, output encoding, and input sanitization measures to address this vulnerability. The recommended mitigation includes applying the vendor's security patches, implementing proper input validation for all user-supplied data, and configuring proper output encoding mechanisms. Additionally, web application firewalls and input validation rules should be configured to detect and prevent such malicious payloads from entering the application. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities within the application's codebase and ensure proper secure coding practices are followed throughout the development lifecycle.
