Unrestricted file upload in InnovaStudio WYSIWYG Editor 5.4 (asset manager)
InnovaStudio WYSIWYG Editor 5.4 contains an unrestricted file upload flaw in its asset manager upload handling. The upload controls can be bypassed via filename manipulation, including use of null-byte techniques and alternate/double file extensions, allowing an attacker to upload dangerous server-side files (e.g., malicious ASP web shells) despite intended file extension restrictions.
