Summary
The RC4 Bar Mitzvah Attack for SSL/TLS affects IBM eDiscovery Identification
and Collection 7.5.1, IBM Policy Assessment and Compliance 7.5.1, IBM
Unstructured Data Identification and Mgmt 7.5.1 and IBM StoredIQ 7.6
Vulnerability Details
CVEID: CVE-2015-2808
DESCRIPTION: The RC4 algorithm, as used in the TLS protocol and SSL protocol,
could allow a remote attacker to obtain sensitive information. An attacker
could exploit this vulnerability to remotely expose account credentials
without requiring an active man-in-the-middle session. Successful exploitation
could allow an attacker to retrieve credit card data or other sensitive
information. This vulnerability is commonly referred to as "Bar Mitzvah
Attack".

Remediation/Fixes
IBM StoredIQ 7.5.1 Application Stack
In this version, the nginx SSL configuration is defined by the script that
sets up HTTPS during the first-boot process (/siq/bin/certcfg). If HTTPS was
not set up on first-boot or subsequently, then no configuration
(/siq/svc/nginx/ssl.conf) will have been created.
For IBM StoredIQ 7.5.1, the procedure is to patch the script, and if it
exists, the configuration file. This can be accomplished using sed and the
ssl.conf and certcfg files.
These are the commands for the certcfg file:
sed -i 's/ssl_protocols .*/ssl_protocols TLSv1 TLSv1.1 TLSv1.2;/' /siq/bin/certcfg
sed -i 's/ssl_ciphers .*/ssl_ciphers HIGH:MEDIUM:+3DES:+DH:!RC4:!SEED:!IDEA:!eNULL:!aNULL;/' /siq/bin/certcfg
These are the commands for the ssl.conf file:
sed -i 's/ssl_protocols .*/ssl_protocols TLSv1 TLSv1.1 TLSv1.2;/' /siq/svc/nginx/ssl.conf
sed -i 's/ssl_ciphers .*/ssl_ciphers HIGH:MEDIUM:+3DES:+DH:!RC4:!SEED:!IDEA:!eNULL:!aNULL;/' /siq/svc/nginx/ssl.conf
After the changes, nginx must be restarted:
/siq/bin/monit restart nginx
IBM StoredIQ 7.5.1 Data Server
These are the sed commands to patch the Apache configuration:
sed -i 's/SSLProtocol .*/SSLProtocol -ALL +TLSv1/' /usr/local/apache/conf/httpd.conf
sed -i 's/SSLCipherSuite .*/SSLCipherSuite HIGH:MEDIUM:+3DES:+DH:!RC4:!SEED:!IDEA:!eNULL:!aNULL/' /usr/local/apache/conf/httpd.conf
After the changes, Apache must be restarted using this command:
/usr/local/apache/bin/apachectl graceful
IBM StoredIQ 7.6.0.3 Application Stack
In this version, the nginx SSL configuration is defined in a separate script from
certcfg (/siq/svc/nginx/nginx-ctl). This script is run every time nginx is restarted,
so there is no need to worry about a pre-existing configuration file
(/siq/svc/nginx/ssl_protocols_ciphers.conf). The IBM StoredIQ 7.6.0.3 includes the
FIPS mode feature, and there are two cipher strings in the file. However, only the
non-FIPS mode must be patched.
The sed command for this fix is:
sed -i 's/ssl_ciphers="HIGH.*"/ssl_ciphers="HIGH:MEDIUM:+3DES:+DH:!RC4:!SEED:!IDEA:!eNULL:!aNULL"/' /siq/svc/nginx/nginx-ctl
After the changes, nginx must be restarted using this command:
/siq/bin/monit restart nginx
Note: Versions of IBM StoredIQ earlier than 7.6.0.3, including 7.6.0.2 and
7.6.0.0, work similar to 7.5.1 as described above. Most customers are at the
current patch level, which is IBM StoredIQ 7.6.0.3.
