D-Link Nuclias Connect vulnerabilities

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.

D-Link Nuclias Connect firmware versions up to 1.3.1.4 contain an observable response discrepancy vulnerability. The 'Login' endpoint returns distinct JSON responses depending on whether the username exists. An unauthenticated remote attacker can enumerate valid usernames.

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 configuration, creating a profile, and adding a network. An authenticated attacker can inject arbitrary JavaScript executed in the context of other users viewing the profile entry.

D-Link Nuclias Connect firmware versions < 1.3.1.4 contain a directory traversal vulnerability within /api/web/dnc/global/database/deleteBackup due to improper sanitization of the deleteBackupList parameter. This can allow an authenticated attacker to delete arbitrary files impacting the integrity and availability of the system.
