        <h2>SQL injection in Android app content provider (NC-SA-2019-005)</h2>
        <p>26th July 2019</p>
        <p>Risk level: <strong>Low</strong></p>
        <p>CVSS v3 Base Score: 2.7 (<a href="https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:P/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:L">AV:P/AC:H/PR:H/UI:R/S:U/C:L/I:N/A:L</a>)</p>
        <p>CWE: <a href="https://cwe.mitre.org/data/definitions/89.html">Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') (CWE-89)</a></p>
        <p>HackerOne report: <a href="https://hackerone.com/reports/291764">291764</a></p>
        <h3>Description</h3>
        <p>The content provider of the app accepted arbitrary strings in the field list of the returned file list. This allowed an attacker to run harmful queries, destroying the local cache of the android app. The server data however was never in danger, so removing the account and setting it up again can fix all problems.</p>
        <h3>Affected Software</h3>
        <ul>
            <li>Nextcloud Android &lt; <strong>3.0.0</strong> (CVE-2019-5454)</li>

        </ul>
        <h3>Action Taken</h3>
        <p>The error has been fixed.</p>
        <h3>Resolution</h3>
        <p>It is recommended that users upgrade to version 3.0.0 or later.</p>
