It is possible to create a specially crafted node name that does not exist as part of the cluster and point it to a malicious node. This can trick the nodes in cluster to believe that the malicious node is a member of the cluster. So, if Solr users have enabled BasicAuth authentication mechanism using the BasicAuthPlugin or if the user has implemented a custom Authentication plugin, which does not implement either \"HttpClientInterceptorPlugin\" or \"HttpClientBuilderPlugin\", his/her servers are vulnerable to this attack. Users who only use SSL without basic authentication or those who use Kerberos are not affected.","publishedAt":"2017-07-07T19:00:00.000Z","updatedAt":"2024-09-16T18:13:03.269Z","severity":null,"assigner":"apache","products":["Apache Software Foundation Apache Solr"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Solr","versions":[{"version":"5.3 to 5.5.4","status":"affected"},{"version":"6.0 to 6.5.1","status":"affected"}]}],"references":["https://security.netapp.com/advisory/ntap-20181127-0003/","http://mail-archives.us.apache.org/mod_mbox/www-announce/201707.mbox/%3CCAOOKt53EgrybaD%2BiSn-nBbvFdse-szhg%3DhMoDZuvUvyMme-Z%3Dg%40mail.gmail.com%3E","http://www.securityfocus.com/bid/99485"],"weaknesses":[],"ingestedAt":"2026-10-29T19:43:54.997Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2017/7xxx/CVE-2017-7660.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2017-7660","state":"PUBLISHED","datePublished":"2017-07-07T19:00:00.000Z","dateUpdated":"2024-09-16T18:13:03.269Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2017-04-11T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"Apache Solr uses a PKI based mechanism to secure inter-node communication when security is enabled.
