D-Link Nuclias Connect firmware versions <= 1.3.1.4 contain an observable response discrepancy vulnerability. The application's 'Login' endpoint returns distinct JSON responses depending on whether the supplied username is associated with an existing account. Because the responses differ in the error.messagestring value, an unauthenticated remote attacker can enumerate valid usernames/accounts on the server. NOTE: D-Link states that a fix is under development.

D-Link Nuclias Connect firmware versions <= 1.3.1.4 contain a stored cross-site scripting (XSS) vulnerability due to improper sanitization of the 'Network' field when editing the configuration, creating a profile, and adding a network. An authenticated attacker can inject arbitrary JavaScript to be executed in the context of other users viewing the profile entry. NOTE: D-Link states that a fix is under development.

D-Link Nuclias Connect firmware versions <= 1.3.1.4 contain an observable response discrepancy vulnerability. The application's 'Forgot Password' endpoint returns distinct JSON responses depending on whether the supplied email address is associated with an existing account. Because the responses differ in the data.exist boolean value, an unauthenticated remote attacker can enumerate valid email addresses/accounts on the server. NOTE: D-Link states that a fix is under development.
