CVE-2025-58403 · Severity: info · Published 2026-10-23

CGM CLININET is a hospital information system used to manage patient records, medical documentation, and clinical workflows across healthcare facilities. A reflected cross-site scripting (XSS) vulnerability allows an unauthenticated attacker to inject malicious code into URLs that, when clicked by a user, executes in the victim's browser. An attacker can exploit this to steal session cookies, impersonate hospital staff, modify patient records, or access sensitive medical data.

## Technical details

This reflected XSS vulnerability stems from improper neutralization of user-supplied input in the application's web interface. An attacker crafts a malicious URL containing JavaScript or HTML payloads which the application reflects back without sanitization, allowing client-side code execution. No authentication is required; the attack succeeds when a victim visits the crafted link, enabling session hijacking and privilege abuse within the hospital system.
