AI description
CVE-2025-24293 is a command injection vulnerability found in Ruby on Rails Active Storage. This flaw occurs when Active Storage, particularly when configured with the `image_processing` gem and `mini_magick` as the image processor, processes image transformations using user-supplied input. The vulnerability stems from certain methods in Active Storage's default allowed list that can circumvent its safety defaults, enabling command injection if arbitrary user input is accepted as valid transformation methods or parameters. This vulnerability specifically impacts applications that expose image transformation options directly to users, allowing them to provide untrusted input for these operations. Exploitation can lead to the execution of arbitrary commands on the server where the application is hosted.
- Description
- # Active Storage allowed transformation methods potentially unsafe Active Storage attempts to prevent the use of potentially unsafe image transformation methods and parameters by default. The default allowed list contains three methods allow for the circumvention of the safe defaults which enables potential command injection vulnerabilities in cases where arbitrary user supplied input is accepted as valid transformation methods or parameters. Impact ------ This vulnerability impacts applications that use Active Storage with the image_processing processing gem in addition to mini_magick as the image processor. Vulnerable code will look something similar to this: ``` <%= image_tag blob.variant(params[:t] => params[:v]) %> ``` Where the transformation method or its arguments are untrusted arbitrary input. All users running an affected release should either upgrade or use one of the workarounds immediately. Workarounds ----------- Consuming user supplied input for image transformation methods or their parameters is unsupported behavior and should be considered dangerous. Strict validation of user supplied methods and parameters should be performed as well as having a strong [ImageMagick security policy](https://imagemagick.org/script/security-policy.php) deployed.

🚨 New from Ethiack: A crafted MATLAB/HDF5 upload can make Rails Active Storage read server secrets. Attackers could then use a stolen secret_key_base to forge a variation key and reach RCE via CVE-2025-24293. Is offensive still a joke to you. 🤣🤣🤣🤣 https://t.co/IPj
