Descriptions

When using Apache Knox SSO prior to 1.6.1, a request could be crafted to redirect a user to a malicious page due to improper URL parsing. A request that included a specially crafted request parameter could be used to redirect the user to a page controlled by an attacker. This URL would need to be presented to the user outside the normal request flow through a XSS or phishing campaign.

Cuando era usado Apache Knox SSO versiones anteriores a 1.6.1, una petición podía ser diseñada para redirigir a un usuario a una página maliciosa debido a un análisis incorrecto de la URL. Una petición que incluyera un parámetro de petición especialmente diseñado podría ser usada para redirigir al usuario a una página controlada por un atacante. Esta URL tendría que ser presentada al usuario fuera del flujo normal de peticiones mediante una campaña de tipo XSS o phishing
