Descriptions

It was found that the AJP connector in undertow, as shipped in Jboss EAP 7.1.0.GA, does not use the ALLOW_ENCODED_SLASH option and thus allow the the slash / anti-slash characters encoded in the url which may lead to path traversal and result in the information disclosure of arbitrary local files.

Se ha descubierto que el conector AJP en undertow, tal y como se incluye en Jboss EAP 7.1.0.GA, no emplea la opción ALLOW_ENCODED_SLASH y, por lo tanto, permite que los caracteres barra diagonal / barra diagonal invertida se cifren en la url, lo que podría conducir a un salto de directorio y resulta en la revelación de información de archivos locales arbitrarios.
