IBM products: IT security warning about a new bug

As the BSI is currently reporting, a vulnerability has been found in IBM products. You can read a description of the vulnerability and a list of affected operating systems and products here.

The Federal Office for Security in der Informationstechnik (BSI) published a security advisory for IBM products on March 27th, 2023. The operating system Appliance and the products IBM SAN Volume Controller, IBM Storwize and IBM FlashSystem are affected by the vulnerability.

The latest manufacturer recommendations regarding updates, workarounds and security patches for this vulnerability can be found here: IBM Security Bulletin: 6962203 (Stand: 26.03.2023).

Security Advisory for IBM Products – Risk: medium

Risk level: 3 (medium)
CVSS Base Score: 5,3
CVSS Temporal Score: 4,6
Remoteangriff: Ja

The Common Vulnerability Scoring System (CVSS) is used to assess the vulnerability of computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to create a priority list based on this for initiating countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used for the severity of a vulnerability. The base score assesses the prerequisites for an attack (including authentication, complexity, privileges, user interaction) and its consequences. With the temporal score, framework conditions that change over time are included in the evaluation. The risk of the current vulnerability is classified as “medium” according to the CVSS with a base score of 5.3.

General recommendations for dealing with IT security gaps

  1. Users of the affected systems should keep them up to date. When security gaps become known, manufacturers are required to remedy them as quickly as possible by developing a patch or a workaround. If security patches are available, install them promptly.

  2. For information, consult the sources listed in the next section. These often contain further information on the latest version of the software in question and the availability of security patches or tips on workarounds.

  3. If you have any further questions or are uncertain, please contact your responsible administrator. IT security officers should regularly check when the IT security warning affected manufacturers makes a new security update available.
