A critical file inclusion vulnerability in snstheme Simen versions up to 4.6 could allow attackers to access sensitive files or execute arbitrary code on affected web servers.

How to fix or mitigate EUVD-2025-18516?

Within 24 hours: Identify all instances of Simen theme version 4.6 or earlier in your environment and document their criticality.

HIGH 8.1

DescriptionCVE.org

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in snstheme Simen allows PHP Local File Inclusion. This issue affects Simen: from n/a through 4.6.

AnalysisAI

PHP Local File Inclusion (LFI) vulnerability in snstheme Simen versions through 4.6 that allows unauthenticated remote attackers to include and execute arbitrary local files via improper control of filename parameters in PHP include/require statements. With a CVSS score of 8.1 and network-based attack vector, this vulnerability enables confidentiality, integrity, and availability compromise; however, the high attack complexity suggests exploitation requires specific conditions or knowledge of the target environment.

Technical ContextAI

This vulnerability stems from CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program), a critical weakness in PHP applications where user-supplied input is passed unsanitized to include(), require(), include_once(), or require_once() functions. The snstheme Simen WordPress theme (CPE identifier likely wp:snstheme:simen) fails to properly validate or sanitize filename parameters before inclusion, allowing attackers to reference arbitrary files accessible to the PHP process (e.g., /etc/passwd, wp-config.php, log files, or uploaded malicious files). The distinction between RFI (Remote File Inclusion) and LFI (Local File Inclusion) in the description suggests the vulnerability primarily affects local file access, though depending on PHP configuration (allow_url_include), remote exploitation may be possible.

RemediationAI

Immediate actions: (1) Update snstheme Simen to version 4.7 or later once released (patch version not explicitly provided, so monitor snstheme official releases and WordPress theme repository); (2) If patch unavailable, implement Web Application Firewall (WAF) rules to detect LFI patterns (e.g., directory traversal sequences like '../', 'etc/passwd', PHP wrappers); (3) Disable PHP's allow_url_include directive in php.ini to prevent RFI via wrapper protocols; (4) Restrict PHP execution permissions on user-uploadable directories; (5) Audit logs for suspicious include/require patterns and local file access attempts. Temporary mitigation: Disable or replace the Simen theme with a patched alternative until updates are available.
