CVE-2025-62075 is a Remote File Inclusion (RFI) vulnerability found in the Simple Payment PHP application developed by Ido Kobelkowsky, affecting versions up to and including 2.4.6. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements, which allows an attacker to supply a remote URL or file path that the application will include and execute. This can lead to arbitrary code execution on the server, compromising confidentiality and integrity of the system. The vulnerability has a CVSS v3.1 base score of 7.3, indicating high severity, with an attack vector over the network (AV:A), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality and integrity is high (C:H/I:H), while availability impact is none (A:N). Although no public exploits are currently known, the nature of RFI vulnerabilities makes them attractive targets for attackers to execute malicious payloads remotely. The vulnerability affects web servers running the Simple Payment application, which is used for payment processing, making it a critical concern for organizations handling financial transactions. The lack of patches at the time of publication necessitates immediate attention to mitigate risk. The vulnerability can be exploited by tricking users into visiting crafted URLs or submitting malicious input that triggers the inclusion of remote files. This can lead to server takeover, data theft, or further lateral movement within the network.

For European organizations, the impact of CVE-2025-62075 could be severe, especially for those using the Simple Payment application in their e-commerce or financial transaction environments. Exploitation could lead to unauthorized disclosure of sensitive payment data, customer information, and internal business logic, resulting in financial losses, reputational damage, and regulatory penalties under GDPR. The integrity of transaction processing could be compromised, enabling fraudulent transactions or manipulation of payment records. Since the vulnerability allows remote code execution, attackers could establish persistent access, deploy ransomware, or pivot to other internal systems. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit, increasing the attack surface. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score indicates that once exploited, the consequences could be critical. Organizations in Europe with significant online payment operations must consider this vulnerability a priority to avoid disruption and data breaches.

1. Monitor vendor communications closely for official patches or updates addressing CVE-2025-62075 and apply them immediately upon release. 2. Until patches are available, implement strict input validation and sanitization on all parameters that influence file inclusion, ensuring only allowed local files can be referenced. 3. Configure PHP settings to disable remote file inclusion by setting 'allow_url_include=Off' and 'allow_url_fopen=Off' in php.ini to prevent inclusion of remote files. 4. Employ Web Application Firewalls (WAFs) with rules designed to detect and block attempts to exploit file inclusion vulnerabilities. 5. Restrict access to the Simple Payment application to trusted networks or VPNs to reduce exposure to external attackers. 6. Conduct security awareness training to reduce the risk of user interaction-based exploitation, such as phishing. 7. Perform regular code audits and penetration testing focused on input handling and file inclusion logic. 8. Implement robust logging and monitoring to detect anomalous requests or file inclusion attempts promptly. 9. Consider isolating the payment application in a segmented network zone with limited privileges to contain potential compromises. 10. Review and update incident response plans to include scenarios involving remote code execution vulnerabilities.
