CVE-2025-58994 is a vulnerability classified as 'Improper Control of Filename for Include/Require Statement in PHP Program,' commonly known as a Remote File Inclusion (RFI) flaw, found in the designervily Greenify product up to version 2.2. The vulnerability arises because the application fails to properly validate or sanitize user-supplied input that controls the filename parameter in PHP include or require statements. This improper control enables an attacker to supply a remote URL or local file path, causing the application to include and execute malicious PHP code remotely. The vulnerability is exploitable over the network without requiring authentication but does require some form of user interaction, such as clicking a crafted link or visiting a malicious page. The CVSS v3.1 base score is 8.1, reflecting high impact on confidentiality and integrity, with no impact on availability. The attacker can execute arbitrary code on the server, potentially leading to data theft, website defacement, or full system compromise. Although no public exploits are currently known, the nature of RFI vulnerabilities makes them attractive targets for attackers. The vulnerability was reserved in early September 2025 and published in November 2025, indicating recent discovery. The lack of patch links suggests that a fix may not yet be publicly available, increasing urgency for mitigation. The vulnerability affects PHP-based web applications, which are widely used across Europe, especially in CMS and custom web solutions.

For European organizations, exploitation of CVE-2025-58994 could lead to severe consequences including unauthorized disclosure of sensitive data, unauthorized modification of website content, and complete takeover of affected web servers. This can disrupt business operations, damage reputation, and lead to regulatory non-compliance, especially under GDPR. Organizations running Greenify on public-facing web servers are at particular risk, as attackers can remotely execute code without authentication. The impact extends to any connected internal systems if the compromised server is used as a pivot point. Given the high usage of PHP in European web infrastructure, the vulnerability could affect a broad range of sectors including government, finance, healthcare, and e-commerce. The lack of known exploits in the wild currently provides a window for proactive defense, but the high severity score and ease of exploitation mean that attackers may develop exploits rapidly. The requirement for user interaction slightly limits automated exploitation but does not significantly reduce risk for phishing or social engineering attacks.

Organizations should immediately audit their use of the Greenify product and identify affected versions. Until a vendor patch is released, apply the following mitigations: 1) Disable allow_url_include and allow_url_fopen directives in PHP configuration to prevent remote file inclusion. 2) Implement strict input validation and sanitization on all user-supplied parameters controlling file inclusion, using whitelisting approaches where possible. 3) Employ web application firewalls (WAFs) configured to detect and block suspicious file inclusion patterns and remote URL requests. 4) Monitor web server logs for unusual include/require requests or errors indicating attempted exploitation. 5) Restrict file system permissions to limit the impact of any successful code execution. 6) Educate users and administrators about phishing risks that could trigger user interaction-based exploits. 7) Plan for rapid deployment of official patches once available from designervily. 8) Consider isolating Greenify instances in segmented network zones to reduce lateral movement risk.
