A vulnerability classified as critical was found in Apache Solr up to 5.5.3/6.4.0. This vulnerability affects an unknown code of the component Replication. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:
When using the Index Replication feature, Apache Solr nodes can pull index files from a master/leader node using an HTTP API which accepts a file name. However, Solr before 5.5.4 and 6.x before 6.4.1 did not validate the file name, hence it was possible to craft a special request involving path traversal, leaving any file readable to the Solr server process exposed. Solr servers protected and restricted by firewall rules and/or authentication would not be at risk since only trusted clients and users would gain direct HTTP access.
The bug was discovered 02/16/2017. The weakness was disclosed 08/30/2017 (Website). The advisory is shared for download at lists.apache.org. This vulnerability was named CVE-2017-3163 since 12/05/2016. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.
The vulnerability was handled as a non-public zero-day exploit for at least 164 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 102044 (Debian DLA-1046-1 : lucene-solr security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 236791 (Red Hat Update for JBoss Enterprise Application Platform 6.4.20 (RHSA-2018:1448)).
Upgrading to version 5.5.4 or 6.4.1 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
