The handler applies `esc_attr()` \u2014 an HTML-context sanitizer that does not strip shell metacharacters \u2014 and concatenates the result, unquoted, into a `php-cli -f \u2026 bmi_restore <file> <remote>` command passed to `exec()`. This makes it possible for authenticated attackers, with Administrator-level access (or any user granted the plugin's `do_backups` capability) and above, to execute arbitrary OS commands as the web-server user, bypassing WordPress hardening constants such as `DISALLOW_FILE_EDIT` and `DISALLOW_FILE_MODS` that would otherwise prevent code execution from the admin UI. This is an incomplete fix of CVE-2023-7002, which patched the same pattern only in the `$_POST['url']` path of `handleQuickMigration()`; the equivalent mitigations (`rawurlencode()` + explicit shell-metachar replacement + double-quoting in `exec()`) were never applied to `$backupName`."}], "title": "Backup Migration <= 2.1.5.1 - Authenticated (Administrator+) OS Command Injection via 'file' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/af6a7052-6dab-42f0-a2af-0cf459d309d7?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/backup-backup/trunk/includes/ajax.php#L3025"}, {"url": "https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3025"}, {"url": "https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3019"}, {"url": "https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3422"}, {"url": "https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/ajax.php#L3444"}, {"url": "https://plugins.trac.wordpress.org/browser/backup-backup/tags/2.1.5.1/includes/initializer.php#L136"}, {"url": "https://plugins.trac.wordpress.org/changeset?new=3540041%40backup-backup%2Ftags%2F2.1.5.2&old=3512153%40backup-backup%2Ftags%2F2.1.5.1"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-77 Improper Neutralization of Special Elements used in a Command ('Command Injection')", "cweId": "CWE-77", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.2, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "at1as"}], "timeline": [{"time": "2026-08-04T18:04:28.000Z", "lang": "en", "value": "Disclosed"}]}}}
