Incomplete filtering of special elements vulnerability exists in RevoWorks SCVX using 'File Sanitization Library' 1.043 and prior versions, RevoWorks Browser 2.2.67 and prior versions (when using 'File Sanitization Option'), and RevoWorks Desktop 2.1.84 and prior versions (when using 'File Sanitization Option'), which may allow an attacker to execute a malicious macro by having a user to download, import, and open a specially crafted file in the local environment.

RevoWorks SCVX, RevoWorks Browser and RevoWorks Desktop provided by J's Communication Co., Ltd. enables users to execute web browsers, accessing drives, folders, files and registries in a sandboxed environment. Users can download files from the internet to the sandboxed environment, sanitizing through "File Sanitization Library" or "File Sanitization Option", and import to the local environment. "File Sanitization Library" and "File Sanitization Option" are implemented with some third-party component, but the component's filtering functionality is incomplete, fails to detect nor remove Microsoft Excel 4.0 (XLM) Macros (CWE-791). The developer reported this vulnerability to IPA to notify users of its solution through JVN. JPCERT/CC and the developer coordinated under the Information Security Early Warning Partnership.
