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) Advisory AKSEC2003-006 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.
