Package        : lucene-solr
Version        : 3.6.2+dfsg-10+deb9u3
CVE ID         : CVE-2019-0193

A security vulnerability was discovered in lucene-solr, an enterprise
search server.

The DataImportHandler, an optional but popular module to pull in data
from databases and other sources, has a feature in which the whole DIH
configuration can come from a request's "dataConfig" parameter. The
debug mode of the DIH admin screen uses this to allow convenient
debugging / development of a DIH config. Since a DIH config can contain
scripts, this parameter is a security risk. Starting from now on, use
of this parameter requires setting the Java System property
"enable.dih.dataConfigParam" to true. For example this can be achieved
with solr-tomcat by adding -Denable.dih.dataConfigParam=true to
JAVA_OPTS in /etc/default/tomcat8.

For Debian 9 stretch, this problem has been fixed in version
3.6.2+dfsg-10+deb9u3.

We recommend that you upgrade your lucene-solr packages.
