Oracle Reports 12c Release (188.8.131.52) provides new security measures for reports run from Oracle Forms Services in non-secure mode:
Oracle Reports allows you to generate random and non-sequential job IDs to make it impossible to predict the job ID for a particular job. See Section 18.9.2, "Generating Random and Non-Sequential Job IDs".
Prior to 12c Release (184.108.40.206), Oracle Reports generated sequential job IDs, making it easy to predict the job ID. This meant that unauthorized or malicious users could potentially view the job output using GETJOBID through
rwservlet to obtain job output that belongs to another user.
Web commands (
rwservlet keywords) are now categorized for added security:
L0: no Web commands allowed.
NO (for backward compatibility with
DIAGNOSTIC=NO in 10g
rwservlet.properties). No Web commands allowed.
YES (for backward compatibility with
DIAGNOSTIC=YES in 10g
rwservlet.properties). Administrator Web commands (DELAUTH, GETSERVERINFO, KILLENGINE, PARSEQUERY, SHOWENV, SHOWJOBS, SHOWMAP, SHOWMYJOBS) are also allowed. AUTHID is required to run administrator commands.
Note:For L2 Web command access, you do not need to pass the authid. The authid parameter is required only for the STOPSERVER command irrespective of the webcommandaccess value.
Administrators are allowed to run both end user and administrator Web commands. For a non-secure Reports Server, the user ID and password for administrators can be set in the identifier element of the Reports Server configuration file.
The new webcommandaccess parameter in the Oracle Reports Servlet (
rwservlet) configuration file (
rwservlet.properties) defines access levels for executing
rwservlet keywords (Web commands). These values can be set using Oracle Enterprise Manager, as described in Section 6.3.4, "Defining Security Policies for Web Commands".
