# CGM CLININET: reflected XSS lets crafted links steal session cookies

CGM CLININET does not neutralize user-supplied input in some URLs, so a crafted link runs attacker JavaScript or HTML in the visitor's browser. An attacker can steal session cookies and act as the victim inside the application.

_Summary, check and fix written by a model from the sources; labelled as such._

## Timeline

- 2026-10-23T21:57:32+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2025-58403
- 2026-10-24T07:15:51+00:00 epss https://api.first.org/data/v1/epss?cve=CVE-2025-58403

## From the sources

CGM CLININET is vulnerable to Reflected Cross-Site Scripting (XSS) due to improper neutralization of user-supplied data. A remote unauthenticated attacker can craft a malicious URL containing JavaScript or HTML code, which is executed in the victim's browser when the URL is visited, allowing the attacker to steal session cookies and perform actions on behalf of the victim within the application.



The vulnerability was confirmed to affect versions up to 2026.MS3 but later versions may also be vulnerable.
