Stored XSS via unsanitized patient address
Published Apr 6, 2022 · Updated Aug 4, 2024
Stored XSS in Apperta Foundation OpenEyes 3.5.1 allows remote authenticated users to execute script in another user's browser. The patient-details update stores the Address1 value without neutralizing HTML or script-bearing event attributes, then renders it when the profile loads. Successful exploitation requires permission to edit patient details and a second user to view the profile, enabling account hijacking, credential theft, data exfiltration, or unauthorized actions in that user's session.
