Multiple vulnerabilities have been reported in Oracle Database, which can be exploited by malicious, local users to disclose potentially sensitive information, manipulate certain data, and gain escalated privileges, by malicious users to conduct SQL injection attacks, by malicious users and malicious people to disclose potentially sensitive information, manipulate certain data, and by malicious people to conduct cross-site request forgery attacks and compromise a vulnerable system.

1) An input sanitisation error exists in the Enterprise Manager Grid Control.

For more information see vulnerability #1:
SA42921

2) An error exists in the "Cluster Verify Utility" component when executing certain commands via named pipes. This can be exploited to e.g. execute arbitrary commands with LocalSystem privileges.

NOTE: This vulnerability affects Windows platforms only.

3) The Administrator web console of the "Database Vault" component allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain unspecified actions by tricking a logged-in administrative user into visiting a malicious web site.

4) Input passed to the mdsys.reset_inprog_index() procedure is not properly sanitised before being used. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation of this vulnerability requires "Execute on MDSYS procedures" privileges.

5) An unspecified error in the "Scheduler Agent" component can be exploited by authenticated users to gain read, insert, and delete access to a subset of accessible data by the component and perform an unauthorized update.

Successful exploitation of this vulnerability requires "Valid User" privileges and multiple authentications.

6) The Administrator web console of the "Database Vault" component does not properly restrict access to the ORACLE_HOME/dv/jlib/dva_webapp/dva_webapp/images/dvcache directory, which contains .gif files containing Session IDs in their names generated by the "Monitor" web page. This can be exploited to disclose the .gif files and e.g. impersonate other users.

The vulnerabilities are reported in the following products:
* Oracle Database 11g Release 2, version 11.2.0.1.
* Oracle Database 11g Release 1, version 11.1.0.7.
* Oracle Database 10g Release 2, versions 10.2.0.3, 10.2.0.4, and 10.2.0.5.
