CVE-2026-115537 in HospitalManagement
Summary
by MITRE • 10/23/2026
A weakness has been identified in gedelumbung HospitalManagement up to c2d45543789a3887067d3915f69d44cfc2cf76a8. This affects the function simpan of the file application/modules/admin/controllers/routing_pages.php of the component URL Validation. This manipulation of the argument url_route causes open redirect. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The identified vulnerability in gedelumbung HospitalManagement represents a classic open redirect flaw within its administrative routing module. Specifically, the weakness resides in the simpan function located at application/modules/admin/controllers/routing_pages.php. This component is responsible for handling URL validation and redirection logic when administrators configure or update route configurations. The core technical failure stems from insufficient sanitization of user-supplied input passed via the url_route argument. Instead of validating that the provided destination belongs to an allowed domain or path structure, the application directly utilizes this untrusted data in a redirect operation without adequate checks against external domains. This lack of strict allow-listing permits attackers to supply arbitrary Uniform Resource Locators as part of their request payload.
From a technical perspective, this flaw aligns with CWE-601, which defines URL Redirection to Untrusted Site (Open Redirect). The vulnerability allows an attacker to manipulate the redirect destination by injecting malicious URLs into the url_route parameter. Because the application does not properly escape or validate these inputs against a whitelist of trusted origins, it blindly redirects users to whatever domain is specified in the request. This behavior creates a significant security gap because the victim's browser will display the hospital management system's URL initially before being redirected away from it. Attackers can leverage this trust relationship by crafting links that appear legitimate but ultimately lead to phishing sites or other malicious destinations.
The operational impact of this vulnerability is primarily centered around social engineering and credential harvesting campaigns. Since the exploit requires no authentication for the initial redirect mechanism in many configurations, it can be initiated remotely with minimal effort. An attacker could distribute a crafted link through email, instant messaging, or web forums that appears to originate from gedelumbung HospitalManagement but actually redirects users to a fraudulent login page designed to capture credentials. This undermines user trust and exposes sensitive hospital data if victims inadvertently enter their usernames and passwords on the phishing site. Furthermore, this vulnerability can be combined with other attacks such as cross-site scripting or session hijacking to escalate privileges within the application environment.
In terms of industry frameworks, this incident maps directly to MITRE ATT&CK technique T1566.002, which covers Phishing: Spearphishing Link. The ability to host malicious content under a trusted domain significantly increases the success rate of spear-phishing attacks against hospital staff and administrators. Additionally, it relates to CWE-79 if the redirect is used in conjunction with stored cross-site scripting vectors where user input is reflected back without proper encoding. The rolling release model employed by this project complicates mitigation efforts as there are no discrete version numbers to patch or update specifically for this flaw. Consequently, users must rely on upstream fixes that may not be immediately available due to the lack of response from the project maintainers despite early notification via issue reports.
Mitigation strategies should focus on implementing strict URL validation mechanisms within the simpan function and any other redirect endpoints in the application. Developers must enforce an allow-list approach where only predefined, trusted domains or relative paths are permitted for redirections. Absolute URLs pointing to external hosts should be rejected unless explicitly whitelisted by system administrators. Additionally, implementing Content Security Policy headers can help mitigate some downstream effects of open redirects by restricting frame sources and script execution contexts. For end-users, awareness training regarding suspicious links is critical until the software vendor provides a patched release that addresses this input validation deficiency.
