Title
MultiJuicer: Login CSRF allows attacker to force victims into their team
Summary
MultiJuicer is used to run separate Juice Shop instances on a central kubernetes cluster without the need for local instances. In versions 8.0.0 through 10.0.0, the team join endpoint (POST /multi-juicer/api/teams/{team}/join) accepted requests with any Content-Type, including text/plain. Because that content type does not trigger a CORS preflight, an attacker could host a cross-site HTML form that auto-submits to the endpoint and forces a victim's browser to log in as the attacker's team. A successful, undetected attacker can cause victims to unwittingly solve Juice Shop challenges under the attacker's team identity. In a CTF context this lets the attacker inflate their team's score using other players' activity, and any sensitive data the victim enters into "their" Juice Shop ends up in the attacker's instance. The vulnerability is exploitable without any prior authentication; the victim
only needs to visit a page the attacker controls while having network access to the MultiJuicer deployment. SameSite=Strict on the session cookie does not mitigate this, because the attack plants a new cookie rather than relying on an existing one. This issue was fixed in version 10.0.1.

En las versiones 8.0.0 a 10.0.0, el endpoint de uni\u00f3n de equipo (POST /multi-juicer/API/teams/{team}/join) aceptaba solicitudes con cualquier Content-Type, incluyendo text/plain. Debido a que ese tipo de contenido no activa un preflight de CORS, un atacante podr\u00eda alojar un formulario HTML de sitio cruzado que se auto-env\u00eda al endpoint y fuerza al navegador de una v\u00edctima a iniciar sesi\u00f3n como el equipo del atacante. Un atacante exitoso y no detectado puede hacer que las v\u00edctimas resuelvan sin saberlo los desaf\u00edos de Juice Shop bajo la identidad del equipo del atacante. En un contexto de CTF, esto permite al atacante inflar la puntuaci\u00f3n de su equipo utilizando la actividad de otros jugadores, y cualquier dato sensible que la v\u00edctima introduzca en \u2019su\u2019 Juice Shop termina en la instancia del atacante. La vulnerabilidad es explotable sin ninguna autenticaci\u00f3n previa; la v\u00edctima solo necesita visitar una p\u00e1gina que el atacante controla mientras tiene acceso de red al despliegue de MultiJuicer. SameSite=Strict en la cookie de sesi\u00f3n no mitiga esto, porque el ataque planta una nueva cookie en lugar de depender de una existente. Este problema se solucion\u00f3 en la versi\u00f3n 10.0.1."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
