Oracle Vuln# AS06
Time to fix 148 days

Details
#######
Oracle Formsbuilder 9.0.4 creates temp files (e.g. s5hs.1htm) in the local
temp (%TEMP%) directory. These temp-files contain the username and password
of the current database connection entered in the Formsbuilder. After closing Formsbuilder these files are not deleted.

This security issued was introduced in Formsbuilder 9.0.4 to avoid another
security issue in older versions of Formsbuilder (cleartext passwords in the
Apache log file).

Example
#######
<html> <head> ORACLE FORMS.</head>
<body onload="document.pform.submit();" >
<form name="pform" action="http://localhost:8889/forms90/f90servlet" method="POST">
<input type="hidden" name="form" value="C:\oracle_security\sql_injection_forms\demo1.fmx">
<input type="hidden" name="userid" value="SCOTT/TIGER@ora10103">
<input type="hidden" name="obr" value="yes">
<input type="hidden" name="array" value="YES">
</form> </body></html>

Workaround
##########
Set the environment variable TMP, TEMP and TMPDIR to a secure location and
delete the temp directory on a regular basis.
