AI-analyzed exploit summary This repository contains a writeup describing CVE-2020-17533, an RCE vulnerability in Apache Struts2 due to improper handling of OGNL expressions. The document outlines the vulnerability, affected versions, and mitigation steps but does not include exploit code.

Description

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.
