CVE-2025-9754 is a 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 improper sanitization or validation of the 'Username' parameter, allowing an attacker to inject malicious scripts. This flaw can be exploited remotely without requiring authentication, although some level of privilege (PR:L) is indicated, suggesting that the attacker might need limited privileges to trigger the vulnerability. The attack vector is network-based (AV:N), with low attack complexity (AC:L), and no user interaction is required (UI:P indicates partial user interaction, likely the victim visiting a crafted page). The impact primarily affects confidentiality and integrity to a limited extent, with no direct impact on availability or system control. The vulnerability is rated medium severity with a CVSS 4.0 score of 5.1. No patches or fixes have been published yet, and no known exploits are reported in the wild. However, the exploit code has been published, increasing the risk of exploitation. Given the nature of the vulnerability, an attacker could execute arbitrary JavaScript in the context of the victim's browser session, potentially leading to session hijacking, credential theft, or unauthorized actions within the hospital management system interface. This is particularly concerning in a healthcare environment where sensitive patient data and critical operational functions are managed.

For European organizations using the Campcodes Online Hospital Management System, this XSS vulnerability poses a significant risk to patient data confidentiality and system integrity. Healthcare providers are prime targets for cyberattacks due to the sensitive nature of the data they handle and the critical services they provide. Exploitation could lead to unauthorized access to patient records, manipulation of user profiles, or phishing attacks targeting hospital staff. This could result in regulatory non-compliance with GDPR, reputational damage, and potential disruption of healthcare services. The medium severity rating suggests that while the vulnerability is not immediately catastrophic, it can be leveraged as part of a broader attack chain, especially if combined with social engineering or privilege escalation. The lack of available patches means organizations must rely on mitigation strategies to reduce exposure. Additionally, the remote exploitability and partial user interaction requirement increase the likelihood of successful attacks if the system is internet-facing or accessible within an intranet.

European healthcare organizations should implement the following specific mitigations: 1) Immediately audit and restrict access to the /edit-profile.php page, ensuring only authorized and trusted users can access it. 2) Employ web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the Username parameter. 3) Conduct input validation and sanitization at the application layer, if possible, by applying patches or custom fixes to neutralize script injection vectors. 4) Educate hospital staff about the risks of clicking on suspicious links or executing unknown scripts, reducing the impact of social engineering. 5) Monitor logs for unusual activity related to profile edits or unexpected script execution attempts. 6) If feasible, isolate the hospital management system from direct internet exposure by using VPNs or secure gateways. 7) Engage with the vendor Campcodes for timely patch releases and apply updates promptly once available. 8) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context.
