This module exploits a command injection vulnerability on the Oracle Endeca | ||
Server 7.4.0. The vulnerability exists on the createDataStore method from the | ||
controlSoapBinding web service. The vulnerable method only exists on the 7.4.0 | ||
branch and isn't available on the 7.5.5.1 branch. On the other hand, the injection | ||
has been found to be Windows specific. This module has been tested successfully | ||
on Endeca Server 7.4.0.787 over Windows 2008 R2 (64 bits). | ||
