中文标题:
AlchemyCMS 安全漏洞
英文标题:
AlchemyCMS has Authenticated Remote Code Execution (RCE) via eval injection in ResourcesHelper
漏洞描述
中文描述:
AlchemyCMS是AlchemyCMS - A Rails CMS Framework开源的一个内容管理系统。 AlchemyCMS 7.4.12之前版本和8.0.3之前版本存在安全漏洞,该漏洞源于在Alchemy::ResourcesHelper#resource_url_proxy中使用Ruby eval函数动态执行由resource_handler.engine_name属性提供的字符串,可能导致经过身份验证的攻击者逃逸Ruby沙箱并在主机操作系统上执行任意系统命令。
英文描述:
Alchemy is an open source content management system engine written in Ruby on Rails. Prior to versions 7.4.12 and 8.0.3, the application uses the Ruby `eval()` function to dynamically execute a string provided by the `resource_handler.engine_name` attribute in `Alchemy::ResourcesHelper#resource_url_proxy`. The vulnerability exists in `app/helpers/alchemy/resources_helper.rb` at line 28. The code explicitly bypasses security linting with `# rubocop:disable Security/Eval`, indicating that the use of a dangerous function was known but not properly mitigated. Since `engine_name` is sourced from module definitions that can be influenced by administrative configurations, it allows an authenticated attacker to escape the Ruby sandbox and execute arbitrary system commands on the host OS. Versions 7.4.12 and 8.0.3 fix the issue by replacing `eval()` with `send()`.
