CVE-2025-15405 identifies a Cross-Site Request Forgery (CSRF) vulnerability in PHPEMS up to version 11.0. CSRF vulnerabilities allow attackers to induce authenticated users to submit forged HTTP requests unknowingly, potentially causing unauthorized actions within the application. The specific vulnerable function is unspecified, but the flaw enables remote attackers to exploit the trust a web application places in the user's browser. The attack vector is network-based with low attack complexity, requiring no privileges or authentication, but does require user interaction in the form of visiting a malicious link or page. The vulnerability impacts the integrity of the system by allowing unauthorized state changes without the user's explicit consent. The CVSS 4.0 vector indicates no impact on confidentiality or availability, and no scope change, meaning the attack is confined to the vulnerable component. No known public exploits exist yet, but the vulnerability is published and should be addressed proactively. PHPEMS is a PHP-based enterprise management system used for business process management, making it a valuable target for attackers seeking to manipulate business workflows or data. The absence of patches at the time of disclosure necessitates immediate compensating controls to mitigate risk.

For European organizations, exploitation of this CSRF vulnerability could lead to unauthorized actions being performed on behalf of legitimate users, potentially altering business data, configurations, or workflows managed by PHPEMS. This could disrupt business operations, cause data integrity issues, or enable further attacks if combined with other vulnerabilities. Organizations in sectors such as finance, manufacturing, or public administration that rely on PHPEMS for enterprise management may face operational risks and reputational damage. The medium severity reflects moderate risk, but the ease of exploitation and lack of required privileges increase the threat landscape. While no confidentiality or availability impact is indicated, integrity violations could have cascading effects on business processes. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks, especially as the vulnerability is publicly known.

European organizations should immediately audit their PHPEMS installations to identify affected versions (up to 11.0). Until official patches are released, implement strict anti-CSRF protections such as synchronizer tokens or double-submit cookies in the application. Review and harden web application firewalls (WAFs) to detect and block suspicious CSRF patterns. Educate users about the risks of clicking unknown links and consider restricting browser access to PHPEMS interfaces from untrusted networks. Monitor logs for unusual state-changing requests that could indicate exploitation attempts. Coordinate with PHPEMS vendors for timely patch releases and apply updates promptly once available. Additionally, conduct security testing focused on CSRF and related web vulnerabilities to identify and remediate similar issues proactively.
