CVE-2026-115537: gedelumbung HospitalManagement open redirect in routing pages

CVE-2026-115537 · Severity: medium · CVSS 4.3 · Published 2026-10-23

HospitalManagement is a simple hospital management system. An administrator can configure custom menu items with URLs, but the application fails to validate these URLs before storing them. This allows an attacker with admin access to inject external URLs that, when accessed by other users, redirect them to attacker-controlled sites for phishing attacks, abusing the hospital's trusted domain.

How to fix

Validate and sanitize the url_route parameter to reject absolute external URLs and protocol-relative URLs in the admin routing_pages simpan function, or restrict the redirect() call to only relative URLs within the application.

Technical details

The simpan function in the admin routing_pages controller accepts a url_route parameter from POST input and stores it directly in the dlmbg_menu table without validation. The web::pages controller then issues a 302 redirect using CodeIgniter's redirect() helper, which interprets URLs starting with http://, https://, or // as absolute external URLs. An authenticated admin can inject arbitrary external URLs that unauthenticated users will be redirected to when accessing menu links.
