A vulnerability has been identified in OZW672 (All versions < V10.00), OZW772 (All versions < V10.00). Vulnerable versions of OZW Web Server use predictable path names for project files that legitimately authenticated users have created by using the applications export function. By accessing a specific uniform resource locator on the web server, a remote attacker could be able to download a project file without prior authentication. The security vulnerability could be exploited by an unauthenticated attacker with network access to the affected system. No user interaction is required to exploit this security vulnerability. Successful exploitation of the security vulnerability compromises the confidentiality of the targeted system.

Weakness

The product makes files or directories accessible to unauthorized actors, even though they should not be.

Affected Software

Name Vendor Start Version End Version
Ozw672_firmware Siemens * 10.00 (excluding)

Extended Description

Web servers, FTP servers, and similar servers may store a set of files underneath a “root” directory that is accessible to the server’s users. Applications may store sensitive files underneath this root without also using access control to limit which users may request those files, if any. Alternately, an application might package multiple files or directories into an archive file (e.g., ZIP or tar), but the application might not exclude sensitive files that are underneath those directories. In cloud technologies and containers, this weakness might present itself in the form of misconfigured storage accounts that can be read or written by a public or anonymous user.
