CVE-2025-47627 is a high-severity vulnerability classified under CWE-98, which pertains to improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the LCweb PrivateContent - Mail Actions plugin, versions up to and including 2.3.2. The flaw allows for PHP Local File Inclusion (LFI), where an attacker can manipulate the filename parameter to include unintended files on the server. This can lead to arbitrary code execution, disclosure of sensitive files, or complete system compromise depending on the files included and the server configuration. The vulnerability arises because the application does not properly validate or sanitize user-supplied input used in include/require statements, enabling attackers to traverse directories or inject malicious payloads. The CVSS v3.1 score of 7.5 reflects a high severity, with network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently observed in the wild, the potential impact is significant due to the ability to execute arbitrary code remotely and compromise the affected systems. The lack of available patches at the time of publication increases the urgency for mitigation and monitoring. This vulnerability is particularly critical for web servers running the affected plugin, as it can be exploited remotely over the network with only user interaction, such as clicking a crafted link or visiting a malicious page. The improper input validation in PHP include/require statements is a common and dangerous flaw that can lead to full system compromise if exploited successfully.

For European organizations, the impact of CVE-2025-47627 can be severe. Organizations using the LCweb PrivateContent - Mail Actions plugin on their web servers risk unauthorized disclosure of sensitive information, including configuration files, user data, or credentials. Successful exploitation can lead to remote code execution, allowing attackers to install backdoors, pivot within the network, or disrupt services, impacting availability. This can result in data breaches, operational downtime, reputational damage, and potential regulatory penalties under GDPR due to inadequate protection of personal data. Since the vulnerability requires only user interaction and no authentication, phishing or social engineering campaigns could be used to trigger exploitation. The high attack complexity somewhat limits mass exploitation but targeted attacks against high-value European entities remain a concern. The lack of patches means organizations must rely on compensating controls until updates are available. Given the criticality of web applications in business operations, especially in sectors like finance, healthcare, and government, this vulnerability poses a tangible risk to European digital infrastructure and data privacy.

1. Immediate mitigation should include disabling or removing the LCweb PrivateContent - Mail Actions plugin if it is not essential to operations. 2. If removal is not feasible, restrict access to the affected web application components via network-level controls such as IP whitelisting or VPN-only access to reduce exposure. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious include/require parameter manipulations and directory traversal attempts. 4. Conduct thorough input validation and sanitization on all user-supplied parameters, especially those used in file inclusion functions, to prevent injection of arbitrary paths. 5. Monitor web server logs and application logs for unusual requests or errors indicative of exploitation attempts. 6. Educate users about the risks of interacting with untrusted links or emails to reduce the likelihood of user interaction exploitation. 7. Prepare for patch deployment by closely following LCweb vendor announcements and applying updates promptly once available. 8. Consider deploying runtime application self-protection (RASP) tools to detect and block exploitation attempts in real time. 9. Perform regular security assessments and code reviews focusing on file inclusion and input handling mechanisms to identify and remediate similar vulnerabilities proactively.
