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 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

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

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

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.

    Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java. It     is a technology suitable for nearly any application that requires full-text search, especially cross-     platform.

    Security Fix(es):

    * It was discovered that Lucene's XML query parser did not properly restrict doctype declaration and     expansion of external entities. An attacker with access to an application using a Lucene XML query parser     could exploit this flaw to perform XML eXternal Entity (XXE) attacks. (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.

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 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:0004 advisory.

    Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss     Application Server.

    This release of Red Hat JBoss Enterprise Application Platform 7.0.9 serves as a replacement for Red Hat     JBoss Enterprise Application Platform 7.0.8, and includes bug fixes and enhancements, which are documented     in the Release Notes document linked to in the References.

    Security Fix(es):

    * It was found that Apache Lucene would accept an object from an unauthenticated user that could be     manipulated through subsequent post requests. An attacker could use this flaw to assemble an object that     could permit execution of arbitrary code if the server enabled Apache Solr's Config API. (CVE-2017-12629)

    * It was discovered that the jboss init script performed unsafe file handling which could result in local     privilege escalation. (CVE-2017-12189)

    * It was found that GZIPInterceptor is enabled when not necessarily required in RESTEasy. An attacker     could use this flaw to launch a Denial of Service attack. (CVE-2016-6346)

    * It was found that the fix for CVE-2017-2666 was incomplete and invalid characters are still allowed in     the query string and path parameters. This could be exploited, in conjunction with a proxy that also     permitted the invalid characters but with a different interpretation, to inject data into the HTTP     response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack,     or obtain sensitive information from requests other than their own. (CVE-2017-7559)

    * It was discovered that the CORS Filter did not add an HTTP Vary header indicating that the response     varies depending on Origin. This permitted client and server side cache poisoning in some circumstances.
    (CVE-2017-7561)

    * It was found that properties based files of the management and the application realm configuration that     contain user to role mapping are world readable allowing access to users and roles information to all the     users logged in to the system. (CVE-2017-12167)

    * It was discovered that Undertow processes http request headers with unusual whitespaces which can cause     possible http request smuggling. (CVE-2017-12165)

    Red Hat would like to thank Mikhail Egorov (Odin) for reporting CVE-2016-6346. The CVE-2017-7559 and     CVE-2017-12165 issues were discovered by Stuart Douglas (Red Hat); the CVE-2017-7561 issue was discovered     by Jason Shepherd (Red Hat Product Security); and the CVE-2017-12167 issue was discovered by Brian     Stansberry (Red Hat) and Jeremy Choi (Red Hat).

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.
