Summary

There is an install.sh script under TIP_HOME (ex: /opt/IBM/tivoli/tipv2)
- - provided and laid by eWAS 7.0 during the install but not used by
TIP. However this install script may provide write previleges to 'others'
which is not required

Vulnerability Details

CVE-2014-3020
CVSS base score: 1.9

Affected Products and Versions

This is only an issue for embedded WAS version 7 and stack products that
use the install.sh script to install eWAS - which means only TIP 2.1 and
2.2 versions (and all fixpacks) are affected

Remediation/Fixes

Formal fix will be available with eWAS FP33 which TIP plans to bundle in
Q4 2014

Workarounds and Mitigations

Please find below the steps to fix the vulnerability

1. Navigate to TIP_HOME folder (ex: /opt/IBM/tivoli/tipv2)

2. Take a backup copy of the install.sh - and rename it as
install.sh.pre-vulnerability

3. Edit install.sh file

4. Find this line in the file: chmod -R o+rw $installRoot/

5. Modify the line to: chmod -R +rw $installRoot/

(please note the removal of 'o' in the above change)

6. Save the file
