CVE-2022-1458Public exploitNetwork attack vector

Session hijacking via unsanitized template filename

Published Apr 25, 2022 · Updated Aug 3, 2024

Stored XSS in OpenEMR before 6.1.0.1 allows remote authenticated users to hijack sessions via crafted template filenames. The document-template manager passes the selected filename to jQuery html() without first applying the project's jsText() escaping function. An authenticated user must store the filename and another user must trigger its rendering, exposing that user's session to script theft.
