CVE-2021-33564: Ruby Dragonfly <1.4.0 – Remote Code Execution

漏洞描述

Ruby Dragonfly before 1.4.0 contains an argument injection vulnerability that allows remote attackers to read and write to arbitrary files via a crafted URL when the verify_url option is disabled. This may lead to code execution. The problem occurs because the generate and process features mishandle use of the ImageMagick convert utility.
