Security vulnerabilities have been discovered in OpenSSL.
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the TLS/DTLS heartbeat functionality. An
attacker could exploit this vulnerability to expose 64k of private memory and
retrieve secret keys. An attacker can repeatedly expose additional 64k chunks
of memory. This vulnerability can be remotely exploited, authentication is not
required and the exploit is not complex. It can be exploited on any system
(ie. server, client, agent) receiving connections using the vulnerable OpenSSL
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
Warning: We strongly encourage you to take action as soon as possible as
potential implications to your environment may be more serious than indicated
by the CVSS score.
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by an implementation error in ECDSA (Elliptic Curve
Digital Signature Algorithm). An attacker could exploit this vulnerability
using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces. This
vulnerability can only be exploited locally, authentication is not required
and the exploit is not complex. An exploit can only partially affect
confidentially, but not integrity or availability.

Affected Products and Versions
IBM Tivoli Composite Application Manager (ITCAM) for Transactions is affected.
ITCAM for Transactions contains multiple sub components (Agents). Only the
Internet Service Monitor (ISM Ã¢Â€Â“ Agent code Ã¢Â€Â˜ISÃ¢Â€Â™) is affected.
Ã‚Â· 7.4 Ã¢Â€Â“ Affected by both CVE-2014-0160 and CVE-2014-0076
Ã‚Â· 7.3 Ã¢Â€Â“ Affected by both CVE-2014-0160 and CVE-2014-0076
Ã‚Â· 7.2 Ã¢Â€Â“ Affected by both CVE-2014-0160 and CVE-2014-0076
Ã‚Â· 7.1 Ã¢Â€Â“ Is only affected by CVE-2014-0076 (ECDSA)

Fix for 7.2 maintenance stream will be available on 30th May 2014.
Customers on older 7.1 and 7.2 releases are strongly encouraged to upgrade to
7.4. Please see Workaround/Mitigation section on additional suggestions on to
mitigate this issue.
After applying the fix, additional instructions are needed for CVE-2014-0160
1) Replace your SSL Certificates.
You need to revoke existing SSL certificates and reissue new certificates. You
need to be sure not to generate the new certificates using the old private key
and create a new private key (ie using "openssl genrsa") and use that new
private key to create the new certificate signing request (CSR).
2) Reset User Credentials
Users of network facing applications protected by a vulnerable version of
OpenSSL should be forced to reset their passwords and should revoke any
authentication or session related cookies set prior to the time OpenSSL was
upgraded and force the user to re-authenticate.
Warning: Your environment may require additional fixes for other products,
including non-IBM products. Please replace the SSL certificates and reset the
user credentials after applying the necessary fixes to your environment.
Workarounds and Mitigations
The Internet Service Monitor (ISM) agent consists of the following parts:
Ã‚Â· Bridge Ã¢Â€Â“ the communications hub between kisagent and the monitors
Ã‚Â· kisagent Ã¢Â€Â“ the IBM Tivoli Monitoring Agent that talks with the TEMS
Ã‚Â· Multiple monitors for different protocols Ã¢Â€Â“ eg HTTP monitor, POP monitor.
OpenSSL vulnerabilities impact ISM as follows:
1. The bridge acts as an OpenSSL server, accepting connections from kisagent
2. The kisagent and the individual monitors are OpenSSL clients, connecting to
3. Some protocol monitors also uses OpenSSL as part of their protocol
monitoring; eg HTTPS monitor uses OpenSSL to form the Secure connection to
1) Securing the Bridge as an OpenSSL server.
Communication to and from the bridge between monitors and the bridge and the
kisagent are secured via OpenSSL. This can be disabled via the properties
file. You set:
BridgeSSLEncryption : 0
Additionally, only monitors and ISM kisagent should be communicating with the
bridge. Firewalls can be used to ensure only ISM kisagent/monitors are
connecting to the bridge.
2) Securing the kisagent and monitors as OpenSSL clients to the bridge.
Disable SSL at the bridge (see previous point).
Ensure that kisagent/monitors ONLY connect to known bridges; this can be
achieved by strict firewall rules and/or configuration management. The
relevant configuration files controlling bridge configuration are located at:
The BridgePort property of the Ã¢Â€ÂœBridge PropertiesÃ¢Â€Â stanza should be explicitly
The property file for the kisagent (kisagent.props) should set BridgeIPAddress
in additional to BridgePort.
3) Securing the individual monitors.
Individual monitors that connect to monitoring targets via OpenSSL are
vulnerable. This is known as reverse Heartbleed, where a malicious server can
attack the client.
Vulnerable monitors and mitigation are as follows:
Ã‚Â· The HTTPS Monitor is vulnerable but you can specify the disableTLS option
which will disable TLS.
Ã‚Â· The POP3 Monitor is exploitable but only if the element specifies STARTTLS.
Those profiles could be disabled
Ã‚Â· The IMAP Monitor is exploitable with any profile which is using a STARTLS
set. Those profiles can be disabled
Ã‚Â· The LDAP Monitor Is exploitable if SIMPLE-SSL is set in the element. Those
profiles can be disabled
