Description

sudo before 1.8.12 does not ensure that the TZ environment variable is associated with a zoneinfo file, which allows local users to open arbitrary files for read access (but not view file contents) by running a program within an sudo session, as demonstrated by interfering with terminal output, discarding kernel-log messages, or repositioning tape drives.

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
