CVE-2021-33564
Remote code execution in Dragonfly
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD, GHSA, Ruby Advisory DB.
Description
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.
