Summary
by MITRE • 10/23/2026
A vulnerability was determined in gedelumbung HospitalManagement up to c2d45543789a3887067d3915f69d44cfc2cf76a8. Impacted is the function kirim of the file application/modules/web/controllers/contact.php of the component Contact Form. Executing a manipulation of the argument nama/email/alamat/telepon/pesan can lead to cross site scripting. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The vulnerability identified in gedelumbung HospitalManagement represents a classic Cross-Site Scripting (XSS) flaw located within the Contact Form component, specifically affecting the kirim function found in application/modules/web/controllers/contact.php. This security defect persists through commit c2d45543789a3887067d3915f69d44cfc2cf76a8 and potentially earlier versions due to the project's rolling release model, which obscures precise version boundaries for affected or updated releases. The core technical flaw stems from insufficient input validation and output encoding of user-supplied data submitted via the contact form fields: nama (name), email, alamat (address), telepon (phone number), and pesan (message). When these arguments are processed by the server-side logic without proper sanitization, malicious scripts embedded within them can be stored or reflected back to users who view the resulting output. This lack of encoding allows attackers to inject executable JavaScript code into web pages viewed by other users, violating the principle of least privilege and compromising the integrity of client-side execution contexts.
From an operational perspective, this vulnerability enables remote attacks that do not require user interaction beyond visiting a compromised page or clicking a crafted link containing the malicious payload. The impact is significant as it allows attackers to hijack user sessions by stealing session cookies, perform actions on behalf of authenticated users such as modifying account settings or submitting fraudulent contact requests, and redirect victims to phishing sites designed to harvest credentials. Furthermore, persistent XSS variants could lead to defacement of the hospital management interface or distribution of malware through drive-by downloads if combined with other browser vulnerabilities. The ability to execute arbitrary scripts in the context of the application's domain grants attackers full control over the user experience and potentially access to sensitive patient data handled by the system, which is particularly critical given the healthcare sector's strict regulatory requirements for data protection such as HIPAA or GDPR depending on jurisdiction.
The exploit has been publicly disclosed, increasing the risk landscape significantly as automated scanners and malicious actors can readily utilize known proof-of-concept code to target instances of this software. The rolling release nature of the product complicates patch management efforts since administrators cannot rely on standard version numbering to determine applicability of fixes. Instead, they must monitor commit logs or security advisories directly from the project repository. Although the project maintainers were informed early via an issue report, their lack of response suggests a potential gap in community engagement or resource allocation for maintaining this specific open-source tool. This delay leaves deployments vulnerable during the window between disclosure and remediation, emphasizing the need for proactive monitoring by system administrators who rely on this software.
Mitigation strategies should focus on immediate defensive measures while awaiting official patches from the development team. Administrators are advised to implement Web Application Firewall rules that detect and block common XSS payloads in HTTP POST requests targeting the contact form endpoint. Input validation should be enforced at both the client and server levels, ensuring that only expected character sets such as alphanumeric characters for names and phone numbers are accepted, while restricting special HTML entities like angle brackets and quotes in message fields unless strictly necessary and properly encoded. Output encoding must be applied consistently when rendering user-supplied data back into HTML contexts to neutralize script execution capabilities. Additionally, implementing Content Security Policy headers can provide a robust layer of defense by restricting the sources from which scripts are allowed to load or execute, thereby mitigating the impact even if an injection attempt succeeds. Long-term resolution requires engaging with the project maintainers to ensure timely updates and considering alternative solutions if critical security responsiveness remains unaddressed in future releases. This vulnerability aligns with CWE-79 Improper Neutralization of Input During Web Page Generation known as Cross-site Scripting, and its exploitation vector corresponds to ATT&CK technique T1059 Command and Scripting Interpreter via browser-based execution contexts.
