A vulnerability allowing unrestricted file upload has been identified in Lenve VHR version 1.0-SNAPSHOT. This issue arises in the Avatar Upload feature, specifically within the FastDFSUtils.upload function, located at /hr/userface. The vulnerability allows logged-in users to upload files with arbitrary extensions, such as SVGs, without proper validation of MIME types or file extensions. This flaw can be exploited remotely, and a proof-of-concept exploit is publicly available.
To address this vulnerability, implement a whitelist for acceptable image extensions, validate the magic bytes of uploaded files, and remove any scripts from SVG files before processing.
