Descriptions
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.
Memcached 1.5.5 contiene una vulnerabilidad de control insuficiente de volumen de mensaje de red (amplificación de red, CWE-406) en el soporte UDP del servidor memcached que puede resultar en una denegación de servicio (DoS) mediante una inundación de red (fuentes fiables reportan una amplificación de tráfico de 1:50.000). Este ataque parece ser explotable mediante conectividad de red en el puerto UDP 11211. Parece ser que esta vulnerabilidad se ha solucionado en la versión 1.5.6 debido a que se deshabilita por defecto el protocolo UDP.
It was discovered that the memcached connections using UDP transport protocol can be abused for efficient traffic amplification distributed denial of service (DDoS) attacks. A remote attacker could send a malicious UDP request using a spoofed source IP address of a target system to memcached, causing it to send a significantly larger response to the target.
