Descriptions

Discourse is an open source platform for community discussion. In affected versions an attacker can poison the cache for anonymous (i.e. not logged in) users, such that the users are shown the crawler view of the site instead of the HTML page. This can lead to a partial denial-of-service. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. There are no known workarounds for this issue.

Discourse es una plataforma de código abierto para la discusión comunitaria. En las versiones afectadas, un atacante puede envenenar la caché para usuarios anónimos (es decir, que no han iniciado sesión), de tal manera que a usuarios les es mostrado la vista del rastreador del sitio en lugar de la página HTML. Esto puede conllevar a una denegación de servicio parcial. Este problema está parcheado en las últimas versiones estables, beta y de prueba de Discourse. No se presentan medidas de mitigación conocidas para este problema
