Dell EMC NetWorker versions prior to 19.3.0.2 contain an improper authorization vulnerability. Certain remote users with low privileges may exploit this vulnerability to perform nsrmmdbd operations in an unintended manner.

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
Emc_networker Dell * 19.3.0.2 (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.
