Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:3451 advisory.

  - Solr: Code execution via entity expansion (CVE-2017-12629)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:3452 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Michael Stepankin and Olga Barinova discovered that Apache Solr was vulnerable to an XXE attack. An attacker could use this vulnerability to remotely execute code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Remote code execution occurs in Apache Solr versions < 7.1.0 with Apache Lucene < 7.1.0 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. This can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Two vulnerabilities have been found in Solr, a search server based on Lucene, which could result in the execution of arbitrary code or path traversal.

Michael Stepankin and Olga Barinova discovered a remote code execution vulnerability in Apache Solr by exploiting XML External Entity processing (XXE) in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. To resolve this issue the RunExecutableListener class has been removed and resolving of external entities in the CoreParser class disallowed.

For Debian 7 'Wheezy', these problems have been fixed in version 3.6.0+dfsg-1+deb7u3.

We recommend that you upgrade your lucene-solr packages.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:3123 advisory.

  - Solr: Code execution via entity expansion (CVE-2017-12629)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Apache Solr running on the remote web server is affected by multiple vulnerabilities as referenced in the advisory.

Solr developers report :

Lucene XML parser does not explicitly prohibit doctype declaration and expansion of external entities which leads to arbitrary HTTP requests to the local SOLR instance and to bypass all firewall restrictions.

Solr 'RunExecutableListener' class can be used to execute arbitrary commands on specific events, for example after each update query. The problem is that such listener can be enabled with any parameters just by using Config API with add-listener command.
