Amazon Linux AMI : memcached (ALAS-2018-964)
Medium Nessus Plugin ID 107235
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionIt was discovered that the memcached daemon listened on UDP port 11211
by default. An attacker could use memcached for UDP amplification
denial-of-service attacks. The UDP port has been disabled by default,
but can still be enabled.
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. (CVE-2018-1000115)
