CVE-2025-60375 is an authentication bypass vulnerability affecting Perfex CRM versions before 3.3.1. The root cause is insufficient server-side validation of login parameters, allowing attackers to submit empty username and password fields and bypass authentication controls entirely. This flaw enables unauthorized access to user accounts, including those with administrative privileges, without requiring valid credentials or any user interaction. The vulnerability arises because the server does not properly verify the presence and validity of authentication parameters before granting access. This can lead to full system compromise, data theft, unauthorized data modification, and potential pivoting within the victim's network. Although no public exploits have been reported yet, the simplicity of the attack vector and the critical nature of the access gained make this a high-risk vulnerability. Perfex CRM is widely used by small and medium enterprises for customer relationship management, making the impact potentially broad. The lack of a CVSS score indicates the need for an independent severity assessment based on the technical details and potential consequences.

For European organizations, exploitation of CVE-2025-60375 could result in unauthorized access to sensitive customer and business data stored within Perfex CRM systems. Attackers gaining administrative access can manipulate or exfiltrate data, disrupt business operations, and potentially use the compromised CRM as a foothold for further attacks on internal networks. This could lead to significant financial losses, reputational damage, and regulatory penalties under GDPR due to data breaches. Organizations relying heavily on Perfex CRM for sales, customer service, and business intelligence are particularly vulnerable. The ease of exploitation without authentication or user interaction increases the risk of automated attacks and widespread compromise. Additionally, sectors such as finance, healthcare, and manufacturing that use CRM data for critical decision-making may face operational disruptions and compliance issues. The threat also raises concerns for third-party service providers and partners connected to affected CRM systems.

Organizations should immediately upgrade Perfex CRM to version 3.3.1 or later where the vulnerability is patched. If upgrading is not immediately feasible, implement strict network-level access controls to restrict login page access to trusted IP addresses. Employ web application firewalls (WAFs) with custom rules to detect and block login requests with empty or malformed credentials. Conduct thorough audits of user accounts for unauthorized access and reset passwords for all administrative users. Enable multi-factor authentication (MFA) on all accounts to add an additional layer of security. Monitor logs for unusual login attempts or access patterns indicative of exploitation attempts. Educate IT staff and users about this vulnerability and the importance of timely patching. Finally, consider isolating the CRM system from critical internal networks until the vulnerability is remediated to limit potential lateral movement.
