Security Bulletin
Summary
WebSphere Application Server may have insecure file permissions after custom startup scripts are run. The custom startup script will not pull the umask from the server.xml. This may cause some log files to have different permissions then expected.
Vulnerability Details

The Websphere security bulletin above provides a link to the required iFix to remediate the vulnerability. However, the iFix requires either eWAS 7.0.0.31 or higher installed.
TIP does not support upgrading Websphere fixpack independently. TIP 2.2.0.15 or TIP 2.2.0.17 or TIP 2.2.0.19 must be applied which will upgrade eWAS to 7.0.0.31 and above. Once TIP FP has been applied, the Websphere iFix can be applied as described in the Websphere bulletin.
Workarounds and Mitigations
Please refer to WAS iFix as described above
