SSLv3 contains a vulnerability that has been referred to as the Padding Oracle
On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in IBM
Description: ClearCase 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
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 for the
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
Affected Products and Versions
The vulnerable components are the CCRC WAN Server / CM Server, ClearCase
remote client, and the integrations with OSLC providers and with ClearQuest.
ClearCase version Status
8.0.1 through 188.8.131.52 Affected
8.0 through 184.108.40.206 Affected
7.1.2 through 220.127.116.11 Affected
7.1.0.x, 7.1.1.x (all versions and fix packs) Affected
CCRC WAN Server/CM Server:
On your server host, apply fixes to IBM HTTP Server to disable SSLv3.
Follow the instructions in the following bulletin:
Security Bulletin: Vulnerability in SSLv3 affects IBM HTTP Server
If your clients connect directly to SSL-enabled ports used by the CCRC profile
of WebSphere Application Server, apply WAS fixes as described in
Security Bulletin: Vulnerability in SSLv3 affects IBM WebSphere Application
Depending on your version of ClearCase, you may need extra steps to apply
7.1.0.x, 7.1.1.x, and 7.1.2.x Document 1390803 explains how to update IBM HTTP
Server and WebSphere Application Server for ClearCase
CM Servers at release 7.1.x. Consult those instructions
when applying the fix.
8.0.0.x, 8.0.1.x Apply the IBM HTTP Server and WebSphere Application
Server fixes directly to your CCRC WAN server host.
No ClearCase-specific steps are necessary.
Clients (CCRC and integration clients):
Apply a fix pack for your appropriate release of ClearCase. These fixes
disable SSLv3 in the client.
Affected Versions Applying the fix
8.0.1.x Install Rational ClearCase Fix Pack 7 (18.104.22.168) for 8.0.1
8.0.0.x Install Rational ClearCase Fix Pack 14 (22.214.171.124) for 8.0
7.1.2.x Customers on extended support contracts should install
7.1.1.x Rational ClearCase Fix Pack 17 (126.96.36.199) for 7.1.2
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. You should verify disabling SSLv3 does not cause any compatibility
Workarounds and Mitigations
Enabling ClearCase clients to use SSLv3:
If you must use SSLv3 (not recommended due to its weaknesses), you can
configure your clients to permit its use.
Client How to enable SSLv3
ClearCase remote client Set Java system properties in the runtime
(CTE, rcleartool, CMAPI) environment. For example, to enable it in
for 8.0.0.x, 8.0.1.x releases the CTE stand-alone client, add these lines
Note: 7.1.x releases of CCRC -vmargs
have never supported SSLv3, -Dcom.ibm.jsse2.disableSSLv3=false
and cannot be configured to -Dcom.ibm.rational.clearcase.transport.client.protocol=SSL
Base ClearCase/ClearQuest Edit <ccase-home>/lib/CCCQ/config.pl to set the
integration v2 new configuration setting CQCC_SERVER_SSLV3 to TRUE
Other integration clients Set a user environment variable CCASE_ENABLE_SSLV3=1
Enabling CCRC WAN Server/CM Server to use SSLv3:
To configure your servers to allow SSLv3, follow the instructions in the WAS
or IHS bulletins referenced above.
In addition, if your servers are configured to use a ClearCase integration
such as CMI or UCM/CQ, you must set the environment variable in the WAS
profile used to run the WAN server. Set the variable CCASE_ENABLE_SSLV3 to 1,
following the instructions in tech note 1254153.
