Security Bulletin
Summary
The OpenSSL heartbleed vulnerability impact is limited to the management and
CIMON interfaces of XIV systems running microcode versions 11.3.0, 11.3.0.a,
11.3.1 11.4.1 and 11.4.1.a.
Vulnerability Details
XIV management and CIMOM uses SSL to provide confidentiality and integrity of
management communications. This vulnerability means that an attacker can
potentially compromise management communication, gaining access to user
credentials and thereby to unauthorized management access of an exposed
system.
Since storage management is usually on an internal and separate network,
exposure to this vulnerability is limited to users with access to the
management network.
The impact is limited to management communication only, as XIV does not use
SSL encryption in the data path.
Affected Products and Versions
XIV Gen3 systems running microcode versions 11.4.1 or 11.4.1.a are vulnerable
via management and CIMOM ports. Versions 11.3.0, 11.3.0.a and 11.3.1 are
vulnerable only via the CIMOM port.
XIV Gen3 systems running older microcode versions are not affected.
XIV Gen2 systems are not affected.
Remediation/Fixes
IBM XIV will release a new microcode version including a fix for this
vulnerability by May 16th, 2014. After upgrading a vulnerable machine, the
machine's SSL certificates and corresponding keys should be replaced. If XIV
users are managed internally (i.e., LDAP authentication is not used), then
the passwords of these should be changed as well (after the certificates have
been replaced). Customers who do not manage their own digital certificates
should contact IBM support for replacement certificates.
Workarounds and Mitigations
The best mitigation is to implement best network security practices on the
XIV management network. If an attacker cannot access this network, he cannot
exploit the vulnerability
