Background
org.apache.solr:solr-core is a package in the Maven ecosystem that provides the core functionality for Apache Solr, an open-source search platform. Solr allows users to create and manage search indexes, perform search queries, and replicate indexes across multiple nodes. The Index Replication feature in Solr enables nodes to pull index files from a master/leader node using an HTTP API. This vulnerability affects Solr versions before 5.5.4 and 6.x before 6.4.1.
Vulnerability Detail
The vulnerability, identified as CVE-2017-3163, is an improper limitation of a pathname (path traversal) issue in org.apache.solr:solr-core. When using the Index Replication feature, Solr nodes can accept a file name via an HTTP API without proper validation. This allows an attacker to craft a special request involving path traversal, potentially exposing any file readable to the Solr server process. However, Solr servers protected by firewall rules and authentication are not at risk, as only trusted clients and users with direct HTTP access can exploit this vulnerability.
How To Fix
Fixed versions by release line
The minimum fixed version depends on the release line you run.
-
< 5.5.45.5.4 -
>= 6.0.0, < 6.4.16.4.1
