Oracle Security Alert #61
Dated: 3 November 2003
Severity: 1
SQL Injection Vulnerability in Oracle9i Application Server
Description
A potential security vulnerability has been discovered in the Portal
component of Oracle9i Application Server, Release 9.0.2. A knowledgeable,
malicious and unauthenticated user can potentially inject a SQL script
through a URL in order to gain unauthorized access to user data in Oracle9i
Application Server.
Products Affected
• Oracle9i Application Server Portal Release 1, v 3.0.9.8.5 (and earlier)
• Oracle9i Application Server Portal Release 2, v 9.0.2.3.0 (and earlier)
Portal version 9.0.2.6 and onwards are not vulnerable.
Components affected (where applicable to the product version):
• List of Values (LOVs)
• Portal DB Provider Forms
• Portal DB Provider Hierarchy
• Portal DB Provider XML component
Platforms Affected
See Patch Availability Matrix.
Required conditions for exploit
An unauthenticated user with HTTP access. Note that Portal is installed
by default with Oracle9i Application Server.
Risk to exposure
Risk to exposure is high. A SQL injection attack via the Internet is, in
Oracle’s opinion, likely if the required conditions listed above are met.
This vulnerability is also susceptible to an insider attack originated on
the corporate Intranet. An unauthenticated user can submit unauthorized SQL
queries on the Oracle9i Application Server Data Dictionary tables and/or
also submit costly (time consuming) queries that may affect the performance
of Oracle9i Application Server.
How to minimize risk
It is not feasible to disable public access from the vulnerable components
to mitigate the risk. Oracle strongly recommends that the patches identified
in this alert be applied.
Follow Oracle’s best practices for database and application server:

http://otn.oracle.com/deploy/security/oracle9i/pdf/9i_checklist.pdf
http://otn.oracle.com/deploy/security/oracle9iAS/
and investigate typical IT deployments of firewalls, etc.
Ramification for customer
Oracle strongly recommends applying the patch for this potential
vulnerability.
Oracle recommends that customers review the severity rating for this
Alert and patch accordingly. See
http://otn.oracle.com/deploy/security/pdf/oracle_severity_ratings.pdf
for a definition of severity ratings.
Patch Information
The patch is platform independent and may be applied across all platforms
on which Portal is supported.

Oracle 9iAS Portal versions:
• Oracle9i Application Server Portal Release 1, v 3.0.9.8.5
