2. CREDIT
========================================
Those vulnerabilities was identified during internal penetration test
by Mehmet INCE from PRODAFT / INVICTUS.
3. DETAILS
========================================
3.1 Authenticated Second Order SQL Injection
-----------------------------------------
AdventNetADSMClient.jar file contains DuplicateComputersListener class definition which is accessible with /Report.do enpoint.
start function of DuplicateComputerLİstener class is as follow (Irrelevant part are omitted.)
public void start(ArrayList attributeList, HttpServletRequest request, ReportBean bean)
{
try
{
... OMITTED ...
this.attrbId = request.getParameter("attrId");
this.tableName = request.getParameter("attrTabName");
this.attrbName = request.getParameter("attrbColName");
... OMITTED ...
}
catch (Exception e)
{
e.printStackTrace();
}
}
It takes user input without validation and set it directly to the class variables such as tableName, attrbName.
And then deriveData function are going to be called with class variables that under the adversary control
during complatedAction function execution.
public void completedAction()
{
if (this.updateDetails)
{
... OMITTED ...
deriveData(this.domainName, this.attrbId, this.attrbName, this.tableName);
... OMITTED ...
}
... OMITTED ...
}
deriveData function definition is as follow.
public void deriveData(String domainName, String attrbId, String attrbName, String tableName)
{
ArrayList list = new ArrayList();
RelationalAPI relationalAPI = RelationalAPI.getInstance();
Connection connection = null;
try
{
TableDefinition tableDef = MetaDataUtil.getTableDefinitionByName(tableName);
ColumnDefinition colDef = tableDef.getColumnDefinitionByName(attrbName);
String dataType = colDef.getDataType();
String selctAttrbCol_defaultValue = "'-'";
if (!dataType.equals("CHAR")) {
... OMITTED ...
}
String query = "select " + tableName + "." + attrbName + "," + tableName + ".domain_name " + " from " + tableName + " inner join " + this.resultTableName + " on " + tableName + ".object_guid=" + this.resultTableName + ".object_guid where " + tableName + "." + attrbName + "!=" + selctAttrbCol_defaultValue + " and " + tableName + ".domain_name='" + domainName + "' and " + this.resultTableName + ".report_generation_id='" + this.generationId + "' group by " + tableName + "." + attrbName + "," + tableName + ".domain_name having count(*) > 1;";
if (!tableName.equalsIgnoreCase(this.baseTableName))
{
String selctAttrbCol = tableName + "." + attrbName;
String parentAttrbCol = this.baseTableName + ".domain_name";
String parentTable = this.baseTableName;String childTable = tableName;
String parentJoinCol = this.baseTableName + ".object_guid";
String childJoinCol = tableName + ".object_guid";
String join = parentTable + " inner join " + childTable + " on " + parentJoinCol + " = " + childJoinCol + " inner join " + this.resultTableName + " on " + parentJoinCol + " = " + this.resultTableName + ".object_guid";
query = "select " + selctAttrbCol + "," + parentAttrbCol + " from " + join + " where " + selctAttrbCol + "!=" + selctAttrbCol_defaultValue + " and " + parentAttrbCol + "='" + domainName + "' and " + this.resultTableName + ".report_generation_id='" + this.generationId + "' group by " + selctAttrbCol + "," + parentAttrbCol + " having count(*) > 1;";
}
ArrayList result = getResult(query, attrbName);
ArrayList subList = new ArrayList();
if (result.size() > 0)
{
... OMITTED ...
}
if (subList.size() > 0)
{
... OMITTED ...
}
else
{
... OMITTED ...
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
As you can see, database query built with user supplied variable without PDO/ORM.

Vulnerable Parameters: attrTabName, attrbColName
IMPORTANT NOTE:
Since whole process are being called as background job, there is no way to successfully exploitation
with Blind and/or Time Based techniques. Since this application mostly runs on Windows operating systems, it's possible to
exfiltrate data with DNS queries.(http://www.slideshare.net/stamparm/dns-exfiltration-using-sqlmap-13163281)
