The Exagrid backup appliance at version suffers from a directory traversal vulnerability at “http://EXAGRID_IP/monitor/data/Upgrade/” (case sensitive) which allows unauthenticated access to detailed log files. Active “support” credentials were found within these logs in Base64 encoded format.

The credentials were confirmed as used to facilitate upgrades on the appliance through a series of Perl scripts. The execution of one such script dumps the encoded credentials into the log file “progress.log” within this directory. These ‘support’ credentials allow for administrative level access to the appliance and its data once decoded.
