Description
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.
