Oracle Forms Builder Password in Temp Files

Name Oracle Forms Builder Password in Temp Files
Systems Affected Oracle Formsbuilder 9.0.4
Severity Low Risk
Category Information disclosure of passwords
Vendor URL http://www.oracle.com/
Author Alexander Kornbrust (ak at red-database-security.com)
Date 12 July 2005 (V 1.00)
Oracle Vuln# AS06
Time to fix 148


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><br /> <head><br /> 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><br /> </body><br /></html>

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

Patch Information
Apply patches for DeveloperSuite mentioned in Metalink Note 311038 on your JDeveloper / DeveloperSuite Installation (normally your client PC).
