Descriptions

Pollbot is open source software which "frees its human masters from the toilsome task of polling for the state of things during the Firefox release process." In Pollbot before version 1.4.4 there is an open redirection vulnerability in the path of "https://pollbot.services.mozilla.com/". An attacker can redirect anyone to malicious sites. To Reproduce type in this URL: "https://pollbot.services.mozilla.com//evil.com/". Affected versions will redirect to that website when you inject a payload like "//evil.com/". This is fixed in version 1.4.4.

Pollbot es un software de código abierto que "libera a sus maestros humanos de la ardua tarea de sondear el estado de las cosas durante el proceso de lanzamiento de Firefox". En Pollbot versiones anteriores a 1.4.4, se presenta una vulnerabilidad de redireccionamiento abierto en la ruta de "https://pollbot.services.mozilla.com/". Un atacante puede redireccionar a cualquier persona a sitios maliciosos. Para reproducir escriba esta URL: "https://pollbot.services.mozilla.com//evil.com/". Las versiones afectadas redireccionaran a ese sitio web cuando inyecte una carga útil como "//evil.com/". Esto es corregido en la versión 1.4.4
