Oracle 9iAS SOAP components allow anonymous users to deploy applications by default

Overview

Oracle Application Server 9iAS installs with Simple Object Access Protocol (SOAP) enabled by default and allows unauthenticated remote users to deploy and undeploy SOAP services and providers.

Description

Oracle Application Server 9iAS supports Simple Object Access Protocol (SOAP), an XML-based protocol used by Oracle for Web administration of database services. Version 1.0.2.2.1 of Oracle 9iAS installs with SOAP components enabled by default. The typical installation of this Oracle product also includes SOAP tools that allow remote Web users to deploy and undeploy SOAP services and providers on the server, without authentication and without notice to the Oracle system adminstrator.

Impact

An attacker can control aspects of the Oracle system in ways not intended by its administrators. The attacker may be able to obtain or modify data or perform other actions that are not authorized.

---

Solution

The CERT/CC is currently unaware of a practical solution to this problem.

---

The following workarounds were suggested by David Litchfield and have not been tested by CERT/CC.

To disable SOAP, delete or comment-out the following lines in the file named “$ORACLE_HOME/Apache/Jserv/etc/jserv.conf”:

ApJServGroup group2 1 1
$ORACLE_HOME/Apache/Jserv/etc/jservSoap.properties
ApJServMount /soap/servlet ajpv12://localhost:8200/soap
ApJServMount /dms2 ajpv12://localhost:8200/soap
ApJServGroupMount /soap/servlet balance://group2/soap

Note that in the lines above, “$ORACLE_HOME” may be spelled out, and the port number may differ from 8200.

To prevent SOAP services from being deployed or undeployed, add the following line to the file named “$ORACLE_HOME/soap/werbapps/soap/WEB-INF/config/soapConfig.xml”:

<osc:option name=“autoDeploy” value=“false” />
