CVE-2014-3448Public exploitNetwork attack vector

Unauthenticated code execution via unrestricted file upload

Published Jan 9, 2020 · Updated Aug 6, 2024

Unrestricted file upload in BSS Continuity CMS 4.2.22640.0 allows remote attackers to execute arbitrary code without authentication. The public record does not identify the upload endpoint, accepted file types, storage path, or server-side validation failure. Network access to the CMS is sufficient; a successful upload permits code execution in the web server's security context.
