Apache Accumulo versions 1.5.0 through 1.10.0 and version 2.0.0 do not properly check the return value of some policy enforcement functions before permitting an authenticated user to perform certain administrative operations. Specifically, the return values of the canFlush and canPerformSystemActions security functions are not checked in some instances, therefore allowing an authenticated user with insufficient permissions to perform the following actions: flushing a table, shutting down Accumulo or an individual tablet server, and setting or removing system-wide Accumulo configuration properties.

Weakness

The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.

Affected Software

Name Vendor Start Version End Version
Accumulo Apache 1.5.0 1.10.0
Accumulo Apache 2.0.0 2.0.0
