Workarounds and Mitigations

The vulnerable log4j library is included in an installable but not deployed application ear file, uddi.ear.

If you haven’t yet applied the 6.X.X-TIV-ITM_TEPS_WAS-IHS_ALL_8.55.20.02, which fixes the uddi.ear, you can delete the ear file without any issues.

The uddi.ear file is located in the “iw” component platform (PLAT) directory under your CANDLEHOME installation directory.

For Unix or Linux run: $CANDLEHOME/bin/cinfo -t iw

and use the platform (PLAT) column in the output

i.e. rm $CANDLEHOME/aix536/iw/installableApps/uddi.ear

Windows:

del %CANDLE_HOME%\CNPSJ\installableApps\uddi.ear
