AppCheck NG was updated to detect the flaw.
From the original advisory:
“There are multiple vulnerabilities in ImageMagick, a package
commonly used by web services to process images. One of the vulnerabilities
can lead to remote code execution (RCE) if you process user submitted images.
The exploit for this vulnerability is being used in the wild.
A number of image processing plugins depend on the ImageMagick library,
including, but not limited to, PHP’s imagick, Ruby’s rmagick and paperclip, and nodejs’s imagemagick.”
