Additional Advisory Data
Solutions
CNA: IBM strongly recommends addressing the vulnerability now. Refer to https://www.ibm.com/support/pages/ds8000-code-recommendation for instructions on how to upgrade the Microcode Bundles listed below and other information. DS8A00 fixes are delivered in Microcode Bundle 10.11.34.1 and 10.12.39.0 Note: Customers currently on 10.11.34.0 may update to 10.11.34.1. This is an HMC-only update and does not require a full code update. DS8900F fixes are delivered in Microcode Bundle 89.44.17.1, 89.44.25.1, 89.44.26.0 and 89.45.10.0. Note: Customers currently on 89.44.17.0 may update to 89.44.17.1. This is an HMC-only update and does not require a full code update. Customers currently on 89.44.25.0 may update to 89.44.25.1. This is an HMC-only update and does not require a full code update. 89.44.26.0 is full code update.
Workarounds
CNA: DS8900F and DS8A00 commonly known as DS8K is installed in client data center and clients control access to the system. DS8K offers multiple security features like LDAP, Multi-factor authentication, audit logging etc., that allows clients to control and audit personnel access to their DS8K. In addition, DS8K has implemented IBM approved challenge-response system to control IBM service personnel accessing the system either locally or remotely. So, a malicious attacker must meticulously bypass multiple layers of authentication by exploiting known open-source vulnerabilities to gain access to DS8K. The first step would be gaining access through the client infrastructure. While the issue must be mitigated at the earliest, it doesn’t pose an immediate vulnerability due to existing access controls implemented in DS8K. In addition, DS8K supports deployment of code fixes either via remote code load process or locally by IBM personnel. DS8K clients can deploy code fixes too.
