"Oracle's RDBMS, a leading database server package, supports stored packages
and procedures through the use of PL/SQL. These packages and procedures can
be accessed through Oracle's Application Server's Portal module. Oracle
Application Server is a web server designed for Oracle applications. Many of
the PL/SQL packages and procedures are vulnerable to SQL Injection. Using
these vulnerabilities an unauthenticated attacker can gain access to all
data in the database from the Internet." – ngssoftware.com
