Detailsinfo

A vulnerability was found in Apache Solr (the affected version is unknown) and classified as critical. Affected by this issue is an unknown code of the component Node Handler. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Apache Solr uses a PKI based mechanism to secure inter-node communication when security is enabled. 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.

The bug was discovered 07/07/2017. The weakness was disclosed 07/07/2017 by Paul (Website). The advisory is shared for download at mail-archives.us.apache.org. This vulnerability is handled as CVE-2017-7660 since 04/11/2017. The attack may be launched remotely. No form of authentication is required for exploitation.
