The lack of proper access controls or authentication mechanisms in these files allows an unauthenticated attacker to retrieve them. This exposure can provide an attacker with the location of backup files, which can then be downloaded and exploited.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3875633732\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual representation of how an unauthenticated attacker might exploit this vulnerability using a simple HTTP GET request:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/wp-content\/plugins\/boldgrid-backup\/cron\/env-info.php HTTP\/1.1\nHost: targetsite.com<\/code><\/pre>\n<p>Or,<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/wp-content\/plugins\/boldgrid-backup\/admin\/restore-info.json HTTP\/1.1\nHost: targetsite.com<\/code><\/pre>\n<p>These requests, if not properly secured, will return sensitive backup file location information that an attacker can then use to download the files directly.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>It is recommended to apply the vendor-provided patch immediately to mitigate this vulnerability. If the patch cannot be applied immediately, use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) as a temporary mitigation measure. Additionally, regular monitoring of system logs for any suspicious activity can also aid in detecting potential exploits.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2020-36848 vulnerability is a security flaw found in the Total Upkeep &#8211; WordPress Backup Plugin by BoldGrid, which exposes sensitive information to unauthorized users.
