Apache Accumulo could allow a remote authenticated attacker to gain elevated privileges on the system, caused by improper validation of the return value of some policy enforcement functions. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain administrative privileges to flushing a table, shutting down Accumulo or an individual tablet server, and setting or removing system-wide Accumulo configuration properties.
