Dragonfly contains remote code execution vulnerability

發布日:2021/6/2修改日:2024/2/16

描述

An argument injection vulnerability in the Dragonfly gem before 1.4.0 for Ruby 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.
