Mitigation for CVE-2011-4642 Cross Site Scripting and Cross Site Request Forgery

mappy.py in Splunk Web in Splunk 4.2.x before 4.2.5 does not properly restrict use of the mappy command to access Python classes, which allows remote authenticated administrators to execute arbitrary code by leveraging the sys module in a request to the search application, as demonstrated by a cross-site request forgery (CSRF) attack, aka SPL-45172.

Can version 4.2.3 of splunk be locked down in any way to mitigate against this?

Yes, you can remove the files mappy.py and reducepy.py and remove or comment out their respective entries from commands.conf.
