The vulnerability identified as CVE-2024-52680 affects EyouCMS version 1.6.7 and represents a critical cross site scripting flaw located within the administrative login endpoint at /login.php?m=admin&c=System&a=web&lang=cn. This vulnerability stems from inadequate input validation and output sanitization mechanisms within the content management system's authentication interface. The flaw allows malicious actors to inject arbitrary JavaScript code into the web application's response, potentially compromising the security of administrative sessions and user data.
The technical implementation of this XSS vulnerability occurs when the application fails to properly escape or filter user-supplied parameters, specifically within the language parameter handling mechanism. When an attacker crafts a malicious payload and submits it through the login interface, the application processes this input without sufficient sanitization before rendering it in the web response. This creates an environment where attacker-controlled JavaScript code can execute within the context of a victim's browser session, particularly affecting administrators who access the vulnerable endpoint. The vulnerability manifests as reflected XSS since the malicious script is reflected back to the user through the application's response without being stored on the server.
The operational impact of this vulnerability extends beyond simple script execution as it provides attackers with potential access to administrative privileges within the CMS environment. An attacker could leverage this vulnerability to steal session cookies, redirect users to malicious sites, perform unauthorized administrative actions, or even escalate privileges within the application. The reflected nature of the vulnerability means that exploitation requires social engineering to deliver the malicious payload to a victim, typically through phishing emails or compromised links. This vulnerability directly violates CWE-79 which categorizes cross site scripting as a fundamental web application security weakness, and aligns with ATT&CK technique T1566.001 for initial access through spearphishing attachments or links.
Mitigation strategies for this vulnerability should prioritize immediate patching of the EyouCMS application to the latest secure version that addresses the XSS flaw in the system administration interface. Organizations should implement comprehensive input validation and output encoding mechanisms across all user-supplied parameters, particularly within administrative endpoints. Network-level protections such as web application firewalls should be configured to detect and block malicious payloads targeting known XSS patterns. Additionally, implementing content security policies can provide an additional layer of defense by restricting the execution of unauthorized scripts within the application context. Security teams should conduct regular vulnerability assessments and penetration testing to identify similar flaws within the application's codebase, while also ensuring that all administrative interfaces maintain strict input validation and sanitization protocols. The vulnerability highlights the critical importance of maintaining up-to-date security practices and implementing defense-in-depth strategies to protect against persistent web application threats.
