Oracle9i Application Server PL/SQL module long help page buffer overflow
|oracle-appserver-modplsql-bo (7727)||High Risk|
Oracle9i Application Server is vulnerable to a denial of service attack caused by a buffer overflow in the PL/SQL Apache Web module. By sending a URL request for an overly long help page, a remote attacker can overflow a buffer in ModPL/SQL and cause the system to crash or execute arbitrary code on the system with system level privileges.
Apply patch number 2128936, available from the Oracle MetaLink Web site. See References.
In addition to applying the patch, change the default "/admin_" path to something other than the default. To change the default "/admin_" path, edit the "adminPath" entry in the wdbsvr.app file located in the $ORACLE_HOME$\Apache\modplsql\cfg directory.
