What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

MISP contains a reflected cross-site scripting (XSS) vulnerability in the workflow module interface. Parameter names returned by the misp-modules service are rendered as raw HTML form labels on the workflow module page without output encoding. An attacker who can influence the parameter names reported by the misp-modules service can inject arbitrary HTML or JavaScript that executes in the context of an authenticated MISP user's browser.

Preconditions:

  • The attacker must be able to control or influence parameter names reported by the misp-modules service.
  • A victim must be authenticated and view the affected workflow module page.

Impact:

  • Execution of arbitrary JavaScript in the victim's browser session.
  • Potential theft of session tokens, manipulation of the MISP interface, or initiation of unauthorized actions on behalf of the victim.

Affected versions: <2.5.48.
