CVE-2025-27953Network attack vector

Account impersonation via URL-exposed session tokens

Published Jun 2, 2025 · Updated Jun 11, 2025

Session-token exposure in Carestream Clinical Collaboration Platform 12.2.1.5 allows remote attackers to impersonate users via leaked URLs. The default.aspx endpoint places the usertoken session secret in a GET query string, exposing it through intercepted requests or browser history. Possession of the URL permits session hijacking and access to confidential application data; the technical report explicitly excludes code execution.
