Oracle Forms Insecure Temporary File Handling
If the number of records in a Oracle Forms application retrieved from the database exceeds the parameter "buffered records" Oracle Forms will create a temp file located in the temp directory of the application server.
This temp file contains an unencrypted copy of the database table used in the Forms application (e.g. creditcard). The default permission for these temp files (format: AAAa
ls -la /tmp
-rw-rw-r-- 1 oracle oinstall 47600 Aug 17 20:30 AAAa15400.TMP
Set the environment variable TMP, TEMP and TMPDIR to a secure location. It depends on the OS of the application server what environment variable will be used.
Delete old AAA* files on a regular basis.
Apply patches for the application server mentioned in Metalink Note 311038 .
