CVE-2024-48024: Keep Backup Daily Information Disclosure

CVE-2024-48024 Overview

CVE-2024-48024 is a sensitive information disclosure vulnerability in the Fahad Mahmood Keep Backup Daily WordPress plugin. The flaw affects all versions up to and including 2.1.3 and is classified under [CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere]. Unauthenticated attackers can retrieve embedded sensitive data over the network without user interaction. The vulnerability stems from improper access controls on backup files or system information generated by the plugin.

Critical Impact
Unauthenticated remote attackers can retrieve sensitive system data from WordPress sites running vulnerable versions of the Keep Backup Daily plugin, exposing backup contents that may include database credentials, user data, and configuration files.

Affected Products

Technical Details for CVE-2024-48024

Vulnerability Analysis

The vulnerability is an information disclosure flaw categorized under CWE-497. The Keep Backup Daily plugin generates backup archives of WordPress installations but fails to adequately restrict access to those backup files or related system metadata. Remote attackers can request these resources directly without authentication, retrieving embedded sensitive data.

WordPress backup plugins typically archive database contents, wp-config.php, user uploads, and plugin configuration. When such archives are exposed through predictable paths or web-accessible directories, an attacker who locates them gains a complete snapshot of the site's secrets. This includes database credentials, authentication keys, salts, and any personally identifiable information stored in the database.

Root Cause

The root cause is missing or insufficient authorization checks on backup storage locations created by the plugin. Files written to predictable locations within the wp-content directory are reachable over HTTP without proper .htaccess restrictions, index file protection, or randomized filenames. The plugin trusts that the web server will not serve these files, which is not enforced by default.

Attack Vector

An unauthenticated remote attacker sends HTTP requests to the WordPress instance to enumerate or directly access backup files created by the plugin. The attack requires no privileges and no user interaction. Once a backup archive is downloaded, the attacker extracts it locally to harvest credentials, session keys, and database contents. See the Patchstack Vulnerability Report for further technical context.

Detection Methods for CVE-2024-48024

Indicators of Compromise

Unexpected HTTP GET requests targeting paths under wp-content/plugins/keep-backup-daily/ or backup output directories
Large outbound responses from the web server to external IPs corresponding to backup archive sizes
Access log entries showing enumeration patterns against .zip, .tar.gz, or .sql files in plugin directories

Detection Strategies

Review WordPress and web server access logs for anonymous requests to backup file paths created by the keep-backup-daily plugin
Monitor for directory listing requests and 200-response file downloads originating from non-administrative IPs
Inventory installed WordPress plugins across the environment and flag any instance of keep-backup-daily at version 2.1.3 or earlier

Monitoring Recommendations

Forward Apache, Nginx, and WordPress audit logs to a centralized analytics platform for retrospective hunting
Alert on HTTP responses larger than a defined threshold from wp-content paths to identify backup file exfiltration
Continuously scan public-facing WordPress sites for exposed backup archives using automated asset discovery

How to Mitigate CVE-2024-48024

Immediate Actions Required

Disable and remove the Keep Backup Daily plugin until a patched version is confirmed available
Delete any existing backup archives created by the plugin from web-accessible directories
Rotate WordPress credentials, database passwords, and authentication salts in wp-config.php if exposure is suspected

Patch Information

No fixed version has been identified in the public advisory at the time of NVD publication. The vulnerability affects Keep Backup Daily from initial release through version 2.1.3. Administrators should consult the Patchstack Vulnerability Report for ongoing patch status and uninstall the plugin if no update is available.

Workarounds

Block HTTP access to plugin backup directories using web server rules or .htaccessDeny from all directives
Move backup storage outside the web root to a directory not served by the HTTP daemon
Place a Web Application Firewall (WAF) rule in front of WordPress to block requests to known backup file extensions in wp-content/plugins/keep-backup-daily/

bash

# Configuration example: block web access to plugin backup directory via .htaccess
# Place this file at wp-content/plugins/keep-backup-daily/.htaccess
<FilesMatch "\.(zip|tar|gz|sql|bak)$">
    Require all denied
</FilesMatch>
