Descriptions

Logstash 1.4.x before 1.4.5 and 1.5.x before 1.5.4 with Lumberjack output or the Logstash forwarder does not validate SSL/TLS certificates from the Logstash server, which might allow attackers to obtain sensitive information via a man-in-the-middle attack.

Logstash en versiones 1.4.x anteriores a la 1.4.5 y en versiones 1.5.x anteriores a la 1.5.4 con salida Lumberjack o el redireccionador Logstash no valida certificados SSL/TLS desde el servidor Logstash, lo que podría permitir que atacantes obtuviesen información confidencial mediante un ataque man-in-the-middle.

Logstash 1.5.3 and prior versions are vulnerable to a SSL/TLS security issue which allows an attacker to successfully implement a man in the middle attack. This vulnerability is not present in the initial installation of Logstash. This insecurity is exposed when users configure Lumberjack output to connect two Logstash instances. In such deployments, a Logstash instance is used to collect logs from a webserver and securely transmit them to a central Logstash instance to perform additional filtering and storing.
