HMC and Log4j

  • 1.  HMC and Log4j

    Hi,
    anyone have any idea if the HMC is in any way affected by the recent log4j vulnerability?
    Would be nice to know if I need to start the planning of emergency HMC updates or not.

    If all else fails I can log a call with IBM but wondered if anyone else had already been privy to any relevant info.

    Hi!

    Well, that's not final proof, but there is at least one indication, that HMCs might not be affected:
    hscroot@mqde01hmcsap01:~> ls /usr/share/java/log4j*
    /usr/share/java/log4j12-1.2.17.jar /usr/share/java/log4j-1.2.17.jar /usr/share/java/log4j-1.jar

    So while log4j is installed, that version isn't affected.... Disclaimer: That doesn't mean, that there is an affected version installed anywere else.


    Best regards,
      Alexander

    PS: Looking at HMC V9R2 M950.

    Hello!

    there are more log4j-Files in several subdirectories under
    • /opt/apache-tomcat-7.0.105
    • opt/hmc/share/jars-9.2.950.5
    e.g. /opt/apache-tomcat-7.0.105/usr/servers/pmc/apps/pmc-ui-war-9.2.950.5-2103160809.war/WEB-INF/lib/log4j-core-2.13.3.jar

    We also use HMC V9R2 M950.

    Looking at HMC V9R2 M950 I am also seeing quite a few entries under /proc with the log4j2.xml extension

    /proc/XXXX/root/console/log4j2.xml

    among others.
