Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionHashBrown CMS through 1.4.6 contains an OS Command Injection vulnerability (CWE-78) in the media upload thumbnail generation routine. Media.generateThumbnail() in src/Server/Entity/Resource/Media.js builds a temporary file path as 'thumbnail' + Path.extname(filename) and passes it, unescaped, into a shell command executed via AppService.exec() ('convert ' + tempFile + ...). The MIME-type filter in getMIMEType() (src/Common/utilities.js) truncates the extracted extension at the first '?' character, while Path.extname() does not, allowing a filename such as 'x.jpg?$(command)' to pass the image-type check while still injecting a shell command substitution into the exec() call. An authenticated user holding the media resource scope can achieve arbitrary OS command execution in the context of the Node.js process via POST /api/{project}/{environment}/media/new. Metrics
