Description

David Litchfield has reported a vulnerability in various Oracle products, which can be exploited by malicious people to bypass certain security restrictions.

The vulnerability is caused due to an error in the Oracle PL/SQL Gateway component during the validation of certain HTTP requests. This can be exploited to bypass the PLSQLExclusion list and gain access to excluded packages and procedures via specially-crafted HTTP requests.

Successful exploitation allows an attacker to gain DBA access to the database server through the web server.

The vulnerability has been reported in the PL/SQL Gateway component included in the Oracle Application Server and the Oracle HTTP Server.

Note: The affected component may also be included in other Oracle products.


Solution
Apply patches from the April Critical Patch Update (see vendor advisory).
