استجابة HTTP ببيانات JSON تحتوي على أسماء جميع قواعد الفهرسة (cores)

"name":"xxxx"

قم بزيارة
http://{xx.com:80}/solr/{core_name}/admin/mbeans?cat=QUERY&wt=json

إذا كانت الوحدة DataImportHandler مستخدمة، فستحتوي استجابة HTTP على:
org.apache.solr.handler.dataimport.DataImportHandler

وإلا، فهذا يعني أن الوحدة DataImportHandler غير مستخدمة (غير متأثرة بالثغرة)

قم بزيارة
http://{xx.com:80}/solr/#/{core_name}/dataimport

إذا كان خادم Solr هذا لا يستخدم وحدة dataimport-handler (غير متأثر بالثغرة)، فستحتوي استجابة HTTP على تلميح:
sorry, no dataimport-handler defined!

وإلا، فهذا يعني أن الوحدة DataImportHandler مستخدمة (متأثر بالثغرة)
