Re: S.Frostie search script found 41 objects with Log4j string

The Java POI stuff is for using Java to generate Excel spreadsheets most
likely..

They are using log4j v1, which is not subject to the new vulnerability.
But the older versions have their own RCE issues.

Having said that, they are unlikely to be exploited in the POI package
assuming you're using the internally to generate spreadsheets from IBM i
processes.

I suppose the exception might be if you had some sort of exposed
page/service that generates spreadsheets on demand.

I am feeling like a fish out of the water here.
I ran the SQL script and found 32 objects. They basically fall in to the
following groups:

/java/poi-4.1.2/lib/log4j-1.2.17.jar

/www/WSERVICE/lwi/runtime/webservicesmax/eclipse/plugins/WebServicesEngine/WEB-INF/classes/log4j.properties

/QIBM/ProdData/OS/WebServices/internal/engines/org.apache.axis2-15/WEB-INF/classes/log4j.properties

/QIBM/UserData/OS/ADMININST/admin4/wlp/usr/servers/admin4/workarea/org.eclipse.osgi/48/data/libcont/WebAdminLibs_1@xxxxxxxxxxxxxxxx
If I am reading these threads correctly, the ones in the QIBM folders just
wait for IBM to come out with some sort of fix/PTF.
I assume the www/WSERVICE same thing, wait for IBM to come out with some
sort of fix/PTF.
That brings us to the java/poi group. If I recall correctly I put these
for various projects. Do I need to remove these folders and reinstall an
updated version?

Its all IBM stuff. I'd wait for PTFs/fixes from them.

If you're not running any external servers (or only the IBM apache one) I
don't think you need to worry.

Thanks David and thanks S.Frostie

Now, what do I do with the 41 objects found?

One thing to keep in mind ... some vendors repackage jar's so their
product is included in a single jar, with all the required classes
included (either as classes or jar's with a special class loader).

This is going to make it very difficult to detect if the vulnerable
classes are used.
