info:
|
|
name: Ruby Dragonfly <1.4.0 - Remote Code Execution
|
|
author: 0xsapra
|
|
severity: critical
|
|
description: 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.
|
|
impact: |
|
|
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system.
|
|
remediation: |
|
|
Upgrade Ruby Dragonfly to version 1.4.0 or later to mitigate this vulnerability.
