CVE-2020-14016

Vulnerability

Navigate CMS version 2.9 r1433 contains a user enumeration vulnerability in the forgot-password feature. The login page at /navigate/login.php accepts a username or email address via a POST request to determine if a password reset should be initiated. When the submitted username or email does not match an existing user, the system returns a JSON response containing the string not_found. This observable response discrepancy allows an unauthenticated remote attacker to distinguish between valid and invalid user identifiers.[2]

Exploitation

An attacker can exploit this vulnerability by sending a POST request to the forgot-password endpoint with a candidate username or email address. The attacker does not need any prior authentication or special privileges. By analyzing the HTTP response body for the presence or absence of the not_found message, the attacker can infer whether the account exists. No user interaction beyond standard web browsing is required, and the attack can be automated to iterate through a list of common usernames or emails.[2]

Impact

Successful exploitation enables an attacker to enumerate registered usernames and email addresses within the Navigate CMS system. This information leak aids targeted attacks, such as credential stuffing, phishing campaigns, or brute-force password attempts against known accounts. The vulnerability does not directly lead to privilege escalation or data breach but significantly reduces the attacker's reconnaissance effort.[2]

Mitigation

The vendor has not released a patched version for this vulnerability as of the publication date (2020-06-24). Administrators should monitor for official updates. As a workaround, the application code could be modified to return a generic message regardless of whether the username or email exists. This vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog.[1][2]
