Vulnerability Assessment Details
Tests for Oracle9iAS default SOAP installation
Detailed Explanation for this Vulnerability Assessment
In a default installation of Oracle 9iAS v.188.8.131.52, it is possible to
deploy or undeploy SOAP services without the need of any kind of credentials.
This is due to SOAP being enabled by default after installation in order to
provide a convenient way to use SOAP samples. However, this feature poses a
threat to HTTP servers with public access since remote attackers can create
soap services and then invoke them remotely. Since SOAP services can
contain arbitrary Java code in Oracle 9iAS this means that a possible hacker
can execute arbitray code in the remote server.
Disable SOAP or the deploy/undeploy feature by editing
$ORACLE_HOME/Apache/Jserver/etc/jserv.conf and removing/commenting
the following four lines:
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 the port number might be different from 8200.
