A new zero-day vulnerability in Log4j was reported on December 9th 2021. The vulnerability is also known and tracked by now under CVE-2021-44228. Here, we would like to update you on why Hoppes' Ship to Shore solution is not affected by that.

Does the Log4j2.x vulnerability affect any parts of the Ship to Shore solution?

Transmission Software

In a nutshell, no. The ship to shore data transmission solution relies on .NET Core. That is why this stack is not affected by CVE-2021-44228.

Shore-Side Cloud Infrastructure

The shore-side infrastructure is hosted on AWS. None of the AWS services that have been identified as vulnerable are used in the solution.

For more details, please refer to the related AWS security bulletin

Ship-Born Data Logging Framework HOWAF

The ship-side data logging framework includes one Java-based component, the report service, required to generate reports from timeseries data. At the time of writing, this service relies on Log4j version 1.2.17. Following the statement of the Apache Software Foundation, this version is not susceptible to the remote code execution (RCE) vulnerability caused by CVE-2021-44228.

However, while investigating this issue we became aware of CVE-2019-17571 and have taken the opportunity to reduce our risk exposure. This fix will be rolled out with the next update of the HOWAF framework.

Thank you for continuing to entrust us with your data.
