CVE-2025-58947 is a vulnerability classified as 'Improper Control of Filename for Include/Require Statement in PHP Program,' commonly known as a Remote File Inclusion (RFI) or Local File Inclusion (LFI) vulnerability, found in the axiomthemes Athos theme for PHP-based web applications. The issue arises because the theme improperly validates or sanitizes user-supplied input used in PHP include or require statements, allowing an attacker to manipulate the filename parameter. This manipulation can lead to the inclusion of unintended local files on the server, enabling attackers to read sensitive data such as configuration files, password files, or application source code. The vulnerability affects all versions of Athos up to and including 1.9, with no specific version exclusions noted. The CVSS v3.1 base score is 8.2, indicating a high severity with network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), low integrity impact (I:L), and no availability impact (A:N). This means an unauthenticated attacker can remotely exploit the vulnerability without user interaction, primarily compromising confidentiality by reading sensitive files, with some potential integrity impact. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and should be considered a significant risk for affected systems. The lack of available patches at the time of disclosure increases the urgency for mitigation through configuration and monitoring.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive data hosted on web servers running the vulnerable Athos theme. Attackers exploiting this flaw can access configuration files containing database credentials, API keys, or other sensitive information, potentially leading to further compromise of internal systems. The integrity impact is lower but still present, as attackers might leverage disclosed information to conduct subsequent attacks. The vulnerability does not affect availability directly but can facilitate lateral movement or privilege escalation. Organizations in Europe with extensive PHP-based web infrastructure, especially those using WordPress or similar CMS platforms with the Athos theme, are vulnerable. The breach of confidential data can lead to regulatory penalties under GDPR, reputational damage, and financial losses. Given the ease of exploitation without authentication or user interaction, the threat is particularly acute for public-facing web applications.

1. Monitor axiomthemes official channels and Patchstack for the release of security patches addressing CVE-2025-58947 and apply them immediately upon availability. 2. Until patches are available, implement strict input validation and sanitization on all parameters that influence file inclusion paths, ideally restricting inclusion to a whitelist of allowed files or directories. 3. Configure the PHP environment to disable remote file inclusion by setting 'allow_url_include' to 'Off' and 'allow_url_fopen' to 'Off' if not required. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block suspicious file inclusion attempts or unusual URL patterns targeting include/require parameters. 5. Conduct regular security audits and code reviews of custom themes and plugins to identify and remediate similar vulnerabilities. 6. Limit file system permissions of the web server user to prevent unauthorized access to sensitive files. 7. Implement monitoring and alerting for anomalous access patterns or error logs indicative of file inclusion attempts. 8. Educate development and operations teams about secure coding practices related to file inclusion and input validation.
