CVE-2025-9754 is a medium-severity cross-site scripting (XSS) vulnerability identified in version 1.0 of the Campcodes Online Hospital Management System, specifically within the /edit-profile.php component's Edit Profile Page. The vulnerability arises from insufficient input validation or sanitization of the 'Username' parameter, allowing an attacker to inject malicious scripts. This flaw can be exploited remotely without requiring authentication (though the CVSS vector indicates a low privilege requirement), and user interaction is necessary for the attack to succeed (e.g., a victim must visit a crafted URL or page). The vulnerability impacts the confidentiality and integrity of user sessions by potentially enabling session hijacking, credential theft, or the execution of arbitrary scripts in the context of the victim's browser. The CVSS 4.0 base score is 5.1, reflecting medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction needed. No known exploits are currently observed in the wild, and no patches have been published yet. The vulnerability is significant because hospital management systems handle sensitive patient data and operational workflows, making any compromise potentially impactful on privacy and healthcare delivery.

For European organizations, especially healthcare providers using Campcodes Online Hospital Management System 1.0, this vulnerability poses a risk to patient data confidentiality and system integrity. Exploitation could lead to unauthorized disclosure of sensitive personal health information, manipulation of user profiles, or session hijacking of hospital staff accounts. This could disrupt hospital operations, erode patient trust, and lead to regulatory non-compliance under GDPR due to data breaches. Additionally, attackers might leverage the XSS flaw as a foothold for further attacks, such as phishing campaigns targeting hospital employees or patients. The risk is heightened in environments where the system is accessible over the internet or within intranets with insufficient network segmentation. Given the critical nature of healthcare services, even medium-severity vulnerabilities can have outsized operational and reputational impacts.

Organizations should immediately audit their deployment of Campcodes Online Hospital Management System 1.0 to identify exposure of the /edit-profile.php page. Until an official patch is released, implement web application firewall (WAF) rules to detect and block suspicious input patterns targeting the Username parameter. Employ strict input validation and output encoding on all user-supplied data, especially in profile editing functionalities. Conduct user awareness training to recognize phishing attempts that may exploit this vulnerability. Network segmentation should be enforced to limit access to the hospital management system only to authorized personnel and devices. Monitor web server logs for unusual requests or repeated attempts to inject scripts. If feasible, consider temporary disabling or restricting access to the vulnerable component until a vendor patch is available. Finally, maintain an incident response plan tailored to healthcare data breaches to respond swiftly if exploitation occurs.
