3MEMCRASHED VULNERABILITY FROM 2018
Introduction
Memcached can be defined as distributed memory catching service speed up websites
which are dynamically driven and also Internet services by catching information and objects
in Random Access Memory. Memcached is absolutely free software which is licensed under t
Revised BSD. It is deployed in datacenter, IaaS connections and clouds as well. The survey
that was done by Rapid7 and SANS ISC, comes with the report that there are currently
100,000 memcached servers that are exposed in the Internet protocol. This report describes
about the memcrashed vulnerability from 2018.The discussion will also be related to how
memcrashed works and it is used. Analysis related to the solutions of the memcrashed
problems are also provided in this report. The analysis also include future importance and
effectiveness of memcrashed. The discussion also focuses on the discussion related to key-
value database, simple examples related to it and uses of key-value database, and how it is
related to memcached.
