Summary

SSLv3 contains a vulnerability that has been referred to as the Padding Oracle
On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in Netezza 
Performance Portal.

Vulnerability Details

CVE-ID: CVE-2014-3566

DESCRIPTION: Product could allow a remote attacker to obtain sensitive 
information, caused by a design error when using the SSLv3 protocol. A remote
user with the ability to conduct a man-in-the-middle attack could exploit this
vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) 
attack to decrypt SSL sessions and access the plaintext of encrypted 
connections.

CVSS Base Score: 4.3

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

Affected Products and Versions

Netezza Performance Portal v 1.0 2.1.1

Remediation/Fixes

IBM recommends that you review your entire environment to identify areas that
enable the SSLv3 protocol and take appropriate mitigation and remediation 
actions. The most immediate mitigation action that can be taken is disabling 
SSLv3.

Workarounds and Mitigations

Disabling SSLv3 in Netezza Performance Portal versions prior to version 2.1:

    Edit ssl.conf file located in /etc/httpd/conf.d/.
    Modify line containing
    SSLProtocol all -SSLv2

    by appending it with
    -SSLv3

    The result of this change should look like this
    SSLProtocol all -SSLv2 -SSLv3

    Save the changes in ssl.conf file.
    Restart Apache service
    service httpd restart


Disabling SSLv3 in Netezza Performance Portal from version 2.1:

    Edit httpd.conf file located in /<NPP_Installation_Directory>/HTTPServer/conf/ 
    (by default it is /usr/local/nzWebAdmin/HTTPServer/conf/ )
    Change this section:

    <VirtualHost *:443>
    DocumentRoot /usr/local/nzWebAdmin/Admin
    SSLEnable
    <Directory />
    SSLCipherRequire SSL_RSA_WITH_RC4_128_SHA
    SSLCipherRequire TLS_RSA_WITH_AES_128_CBC_SHA
    SSLCipherRequire TLS_RSA_WITH_AES_128_CBC_SHA256
    SSLCipherRequire TLS_RSA_WITH_AES_256_CBC_SHA
    SSLCipherRequire TLS_RSA_WITH_AES_256_CBC_SHA256
    SSLCipherRequire TLS_RSA_WITH_AES_256_GCM_SHA384
    </Directory>
    # Enable only TLSv12 and SSLv3
    SSLProtocolDisable SSLv2 TLSv10 TLSv11
    </VirtualHost>

    by deleting
    SSLCipherRequire SSL_RSA_WITH_RC4_128_SHA

    and adding SSLv3 value to
    SSLProtocolDisable SSLv2 TLSv10 TLSv11

    The result of this change should look like
    <VirtualHost *:443>
    DocumentRoot /usr/local/nzWebAdmin/Admin
    SSLEnable
    <Directory />
    SSLCipherRequire TLS_RSA_WITH_AES_128_CBC_SHA
    SSLCipherRequire TLS_RSA_WITH_AES_128_CBC_SHA256
    SSLCipherRequire TLS_RSA_WITH_AES_256_CBC_SHA
    SSLCipherRequire TLS_RSA_WITH_AES_256_CBC_SHA256
    SSLCipherRequire TLS_RSA_WITH_AES_256_GCM_SHA384
    </Directory>
    # Enable only TLSv12 and SSLv3
    SSLProtocolDisable SSLv2 TLSv10 TLSv11 SSLv3
    </VirtualHost>
    Save the changes in httpd.conf file.
    Restart Nzportal-IHS service.
    service nzportal-ihs restart
