CVE-2024-41519 identifies a Cross Site Scripting (XSS) vulnerability in Feripro software versions up to 2.2.3. The vulnerability is located in the administrative URL path "/admin/programm/<program_id>/zuordnung/veranstaltungen/<event_id>", specifically through the "school" input field. This input field does not properly sanitize user-supplied data, allowing an attacker with authenticated access to inject malicious JavaScript code. When a victim user interacts with the affected page, the injected script can execute in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions within the application. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) indicates that the attack can be launched remotely over the network with low complexity, requires privileges (authenticated user), and user interaction is necessary. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is low but non-negligible, while availability is not affected. No known public exploits or patches are currently available, highlighting the need for proactive mitigation. The vulnerability is classified under CWE-79, a common web application security weakness related to improper input validation and output encoding.

The primary impact of CVE-2024-41519 is the potential compromise of user confidentiality and integrity within the Feripro application. Successful exploitation can allow attackers to execute arbitrary scripts in the context of authenticated users, leading to session hijacking, theft of sensitive information, or unauthorized actions such as privilege escalation or data manipulation. Although availability is not impacted, the breach of trust and data integrity can disrupt organizational workflows, especially in environments where Feripro is used for managing programs and events. The requirement for authenticated access and user interaction limits the attack surface but does not eliminate risk, particularly in organizations with many users or weak internal controls. The absence of known exploits reduces immediate threat but also means defenders must be vigilant for emerging attacks. Organizations relying on Feripro for administrative functions could face reputational damage and compliance issues if this vulnerability is exploited.

To mitigate CVE-2024-41519, organizations should implement strict input validation and output encoding on the "school" input field within the affected URL path to prevent injection of malicious scripts. Employing a robust Content Security Policy (CSP) can help restrict the execution of unauthorized scripts. Web Application Firewalls (WAFs) should be configured to detect and block suspicious payloads targeting this endpoint. Since no official patch is currently available, administrators should limit access to the affected administrative interface to trusted users and networks, enforce strong authentication mechanisms, and monitor logs for unusual activity indicative of exploitation attempts. User education about phishing and social engineering risks can reduce the likelihood of successful user interaction exploitation. Regular security assessments and penetration testing focused on input validation can help identify and remediate similar vulnerabilities proactively. Finally, maintain close communication with the vendor for updates and patches.
