The vulnerability CVE-2024-54919 represents a stored cross site scripting flaw in the kashipara E-learning Management System version 1.0, specifically within the /teacher_avatar.php component. This type of vulnerability falls under the CWE-79 category, which encompasses cross site scripting attacks where malicious scripts are injected into web applications and subsequently executed in the victim's browser. The vulnerability is classified as stored XSS because the malicious payload persists in the application's database and is executed whenever the affected page is accessed, rather than being reflected in a single request.
The technical implementation of this vulnerability occurs through the filename parameter in the teacher_avatar.php script, which fails to properly sanitize or validate user input before processing it as part of the application's avatar handling functionality. When an attacker submits a malicious filename containing javascript code, the system stores this input without adequate filtering mechanisms, allowing the script to be executed in the context of any user who views the affected page. This flaw demonstrates inadequate input validation and output encoding practices that are fundamental to preventing XSS attacks according to OWASP top ten security principles.
The operational impact of this vulnerability extends beyond simple script execution as it provides attackers with the capability to perform session hijacking, deface the application interface, steal user credentials, or redirect victims to malicious websites. The remote exploitation nature of this vulnerability means that attackers can leverage it without requiring physical access to the system or prior authentication, making it particularly dangerous in educational environments where multiple users interact with the platform. The stored nature of the vulnerability also means that the malicious payload remains persistent, potentially affecting numerous users over extended periods without requiring repeated exploitation attempts.
Security mitigations for this vulnerability should focus on implementing comprehensive input validation and output encoding mechanisms throughout the application's data flow. The system should employ strict parameter validation for the filename parameter, rejecting or sanitizing any input containing script tags or other malicious code patterns. Additionally, the application should implement proper output encoding when displaying user-supplied data in web pages, ensuring that any potentially dangerous characters are properly escaped. The remediation process should include input sanitization using established libraries or frameworks that can handle various script injection attempts, while also implementing Content Security Policy headers to add an additional layer of protection against script execution. This vulnerability highlights the importance of following secure coding practices as outlined in the OWASP Secure Coding Practices and demonstrates how basic input validation failures can lead to severe security implications in web applications.
