Issue:
What should I do about the log4j.jar security issue discovered in December 2021? Wikipedia
Possible Solutions:
All of our products are based upon the MATLAB platform, and each installation of MATLAB includes a copy of the log4j.jar file. We recommend that you remove the Matlab-related log4j.jar file immediately.
If you are a PLS_Toolbox user, you will find this file starting from the top level MATLAB folder under topLevelMATLABfolder/java/jarext. Note that under macOS and Linux, you will have to navigate inside of the application bundle for MATLAB under those platforms.
Our testing thus far indicates that removal of this file will cause some error messages upon the startup of MATLAB, but functionality otherwise remains. PLS_Toolbox or compiled products (Solo, Solo+MIA, Solo_Predictor,...) should work normally as they do not depend on log4j.
For our compiled products Solo (and variants) and Solo_Predictor, this file will found under the folder structure for the MATLAB Runtime engine, the location of which is operating system dependent. The file should be listed by the appropriate search tool and our limited testing thus far indicates no issues with Solo or Solo_Predictor. If Solo were installed in the default location on Windows then the log4j file is at: C:\Program Files\EVRI\Solo\application\java\jarext\log4j.jar.
We recommend that you contact The Mathworks regarding this issue to get their official response.
