CVE-2024-50841 identifies a stored Cross-Site Scripting (XSS) vulnerability in the KASHIPARA E-learning Management System Project 1.0, located in the /admin/calendar_of_events.php script. The vulnerability arises because the application fails to properly sanitize or encode user-supplied input in the date_start, date_end, and title parameters before storing and rendering them in the administrative calendar interface. As a result, an authenticated attacker with at least limited privileges can inject arbitrary JavaScript code that will be stored on the server and executed in the browsers of users who view the affected calendar page. This stored XSS can lead to session hijacking, theft of sensitive cookies, or execution of malicious actions on behalf of legitimate users, potentially escalating privileges or compromising administrative functions. The vulnerability requires authentication (PR:L) and user interaction (UI:R), limiting its exploitation scope but still posing a significant risk within the administrative context. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates network attack vector, low attack complexity, privileges required, user interaction required, scope changed, and low impact on confidentiality and integrity with no availability impact. No patches or known exploits are currently documented, highlighting the need for proactive mitigation. The vulnerability is classified under CWE-79, a common web application security weakness related to improper neutralization of input leading to XSS.

The primary impact of CVE-2024-50841 is the compromise of confidentiality and integrity within the KASHIPARA E-learning Management System's administrative interface. Successful exploitation allows attackers to execute arbitrary scripts in the context of other administrative users, potentially leading to session hijacking, credential theft, unauthorized actions, or further exploitation of the system. While availability is not directly affected, the breach of administrative controls can indirectly disrupt system operations or lead to data manipulation. Organizations relying on this e-learning platform risk unauthorized access to sensitive educational data, user information, and administrative functions. The requirement for authentication and user interaction limits the attack surface but does not eliminate risk, especially in environments with multiple administrators or less stringent access controls. The absence of known exploits in the wild suggests limited current threat but does not preclude future exploitation. The vulnerability could be leveraged in targeted attacks against educational institutions or organizations using this platform, potentially impacting privacy and operational integrity.

To mitigate CVE-2024-50841, organizations should implement the following specific measures: 1) Apply any available patches or updates from the KASHIPARA E-learning Management System vendor as soon as they are released. 2) If patches are not yet available, implement input validation and output encoding on the date_start, date_end, and title parameters to neutralize malicious scripts before storage and rendering. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the administrative interface. 4) Limit administrative access strictly to trusted personnel and enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of attacker access. 5) Monitor logs and user activity for unusual behavior indicative of XSS exploitation attempts. 6) Educate administrators about the risks of clicking on suspicious links or interacting with untrusted content within the admin interface. 7) Consider deploying web application firewalls (WAFs) with rules targeting XSS payloads specific to this application context. 8) Regularly audit the application and its inputs for similar injection vulnerabilities to prevent future occurrences.
