- Summary
- MISP TAXII Object Viewer Stored XSS via Unescaped JSON Output
- Details
-
MISP contains a cross-site scripting (XSS) vulnerability in the TAXII object viewer. When displaying a remote TAXII object, the JSON content of string properties was rendered directly into an HTML pre block without HTML-encoding. An attacker who can control or influence the content of a TAXII object (e.g., by publishing a malicious object to a TAXII server that the victim's MISP instance subscribes to) can inject arbitrary HTML or JavaScript that executes in the context of the victim's MISP session.
Preconditions:
-
The victim must be an authenticated MISP user with access to the TAXII object viewer.
-
The victim must open or view the crafted TAXII object.
Impact:
-
Execution of arbitrary JavaScript in the victim's browser within the MISP application context.
-
Potential theft of session tokens, API keys, or other sensitive data accessible from the MISP interface.
-
Potential for performing actions on behalf of the authenticated user.
Affected versions: <2.5.48.
