CVE-2025-63514 identifies a Cross-Site Scripting (XSS) vulnerability in the kishan0725 Hospital Management System, specifically within the appsearch.php script via the email parameter. XSS vulnerabilities occur when an application does not properly sanitize user-supplied input, allowing attackers to inject malicious scripts that execute in the context of other users' browsers. This vulnerability is classified under CWE-79, indicating improper neutralization of input during web page generation. The vulnerability can be exploited remotely over the network without requiring authentication (AV:N/PR:N), but it requires user interaction (UI:R) to trigger the malicious script execution. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component, potentially impacting the entire application or user session. The impact affects confidentiality and integrity (C:L/I:L) but not availability (A:N). An attacker could leverage this vulnerability to steal session cookies, perform phishing attacks, or manipulate displayed data, compromising patient privacy and hospital data integrity. Although no known exploits are currently in the wild and no patches have been released, the presence of this vulnerability in a hospital management system poses a significant risk due to the sensitive nature of healthcare data. The CVSS score of 6.1 reflects medium severity, balancing the ease of exploitation with the requirement for user interaction and the limited impact on availability. The vulnerability was reserved on 2025-10-27 and published on 2025-11-18, indicating recent discovery and disclosure.

For European organizations, especially those in the healthcare sector, this vulnerability could lead to unauthorized disclosure of sensitive patient information, undermining patient confidentiality and trust. Attackers exploiting this XSS flaw could hijack user sessions, leading to unauthorized access to hospital management functions or patient records. This could result in data manipulation, fraud, or disruption of hospital operations. Given the critical nature of healthcare services, even a medium-severity vulnerability can have outsized consequences, including regulatory penalties under GDPR for data breaches. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit, increasing the risk of targeted attacks against hospital staff. The lack of a patch means organizations must rely on mitigations and monitoring until a fix is available. Overall, the vulnerability poses a moderate risk to confidentiality and integrity, with potential operational impacts if exploited.

European healthcare organizations using the kishan0725 Hospital Management System should immediately implement input validation and output encoding on the email parameter within appsearch.php to prevent script injection. Employing a strict Content Security Policy (CSP) can help mitigate the impact of any injected scripts by restricting the sources from which scripts can be executed. User awareness training should be enhanced to reduce the risk of successful phishing attacks that could trigger the vulnerability. Network-level protections such as Web Application Firewalls (WAFs) should be configured to detect and block malicious payloads targeting the email parameter. Regular security scanning and penetration testing focused on XSS vulnerabilities should be conducted. Until an official patch is released, organizations should consider isolating or restricting access to the vulnerable module and monitor logs for suspicious activities related to appsearch.php. Coordinating with the vendor for timely patch development and deployment is critical.
