E-Business Designer (eBD) 3.1.4 and earlier allows remote attackers to upload or modify arbitrary files and execute arbitrary code via a direct request to (1) common/html_editor/image_browser.upload.html (2) common/html_editor/image_browser.html or (3) common/html_editor/html_editor.html. NOTE: this can also be used for cross-site scripting (XSS) attacks by uploading cascading style sheet (.CSS) files.
