CVE-2025-64216: SmartMag PHP File Inclusion Vulnerability

CVE-2025-64216 Overview

CVE-2025-64216 is a PHP Local File Inclusion (LFI) vulnerability affecting the ThemeSphere SmartMag WordPress theme through version 10.3.0. The flaw stems from improper control of filenames passed to PHP include or require statements [CWE-98]. An authenticated attacker with low privileges can manipulate file path parameters to include arbitrary local PHP files on the server. Successful exploitation can lead to disclosure of sensitive configuration data, execution of attacker-controlled PHP code, and full compromise of the WordPress instance.

Critical Impact

Authenticated attackers can include arbitrary local PHP files, potentially leading to remote code execution and full compromise of WordPress sites running SmartMag through version 10.3.0.

Affected Products

• ThemeSphere SmartMag WordPress theme (smart-mag)
• Versions: from n/a through 10.3.0
• WordPress sites running the vulnerable SmartMag theme

Technical Details for CVE-2025-64216

Vulnerability Analysis

The vulnerability resides in the SmartMag theme code that constructs file paths for PHP include or require statements using attacker-influenced input. Because the theme does not adequately sanitize or restrict the supplied filename, an attacker can traverse the filesystem and reference arbitrary local files. Once an attacker controls which PHP file is included, the server executes that file's code in the context of the WordPress process. This converts a file inclusion primitive into a code execution primitive when combined with writable log files, uploaded media, or other PHP-parsable content on disk.

Root Cause

The root cause is improper control of filenames used in PHP include or require statements [CWE-98]. The vulnerable code path accepts user-supplied data and uses it directly, or with insufficient validation, when resolving the path passed to PHP's file inclusion functions. There is no allowlist of permitted templates or normalization to enforce that the resulting path remains within an expected directory.

Attack Vector

The attack vector is network-based and requires low-privileged authentication on the target WordPress site. An attacker submits a crafted request containing a manipulated file path parameter to a SmartMag endpoint that performs dynamic file inclusion. The server then loads and executes the referenced PHP file. Attack complexity is rated high, reflecting that exploitation depends on specific configuration or chained primitives, such as the ability to write attacker-controlled content to a known path before triggering inclusion.

No verified public proof-of-concept code is available at the time of writing. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2025-64216

Indicators of Compromise

• HTTP requests to SmartMag theme endpoints containing path traversal sequences such as ../, ..%2f, or absolute filesystem paths in query or POST parameters.
• Unexpected access to sensitive files such as wp-config.php, /etc/passwd, or PHP session and log files from the web server process.
• New or modified PHP files in the wp-content/themes/smart-mag/ directory or in upload directories that are subsequently referenced via inclusion.
• Web server error logs showing PHP include() or require() warnings referencing unusual file paths.

Detection Strategies

• Inspect web access logs for requests targeting SmartMag PHP files with parameters whose values resemble file paths.
• Deploy WordPress-aware web application firewall rules that flag PHP LFI patterns and null-byte or encoded traversal attempts.
• Apply file integrity monitoring to the SmartMag theme directory and the WordPress uploads directory to surface unauthorized writes.

Monitoring Recommendations

• Forward WordPress, PHP-FPM, and web server logs to a centralized analytics platform and alert on PHP inclusion errors.
• Correlate authentication events with subsequent requests containing path-like parameters to identify low-privileged accounts probing inclusion endpoints.
• Track outbound connections from the web server that could indicate post-exploitation activity following successful inclusion.

How to Mitigate CVE-2025-64216

Immediate Actions Required

• Identify all WordPress sites using the ThemeSphere SmartMag theme and confirm the installed version.
• Upgrade SmartMag to a release later than 10.3.0 once a fixed version is published by ThemeSphere.
• Audit WordPress user accounts and revoke or reset credentials for low-privileged accounts that are no longer required.
• Review the SmartMag theme directory and uploads for unexpected PHP files that may have been staged for inclusion.

Patch Information

Consult the Patchstack Vulnerability Report for vendor patch status and update guidance. Apply the vendor-supplied update for SmartMag as soon as it is available and verify the theme version after upgrade.

Workarounds

• Restrict access to the WordPress admin interface and SmartMag endpoints using IP allowlisting or VPN-only access until the theme is patched.
• Configure the web server or a WAF to block requests containing path traversal sequences and absolute filesystem paths in parameters handled by SmartMag.
• Set PHP open_basedir to constrain file inclusion to the WordPress installation directory and prevent traversal to system locations.
• Disable the SmartMag theme and switch to an alternative theme if patching cannot be performed promptly.

# Example: restrict PHP file access using open_basedir in php.ini
open_basedir = "/var/www/html/:/tmp/"

# Example: block common LFI traversal patterns at the web server (nginx)
location ~* \.php$ {
    if ($args ~* "(\.\./|\.\.%2f|%00)") {
        return 403;
    }
}
