CVE-2025-10161 is a vulnerability classified under CWE-307 (Improper Restriction of Excessive Authentication Attempts), CWE-602 (Client-Side Enforcement of Server-Side Security), and CWE-807 (Reliance on Untrusted Inputs in a Security Decision) affecting Turkguven Software Technologies Inc.'s Perfektive product versions before 12574 Build 2701. The core issue stems from the product's failure to properly restrict the number of authentication attempts, allowing attackers to conduct brute force attacks against user credentials. Additionally, the product incorrectly enforces security controls on the client side rather than on the server side, making it possible for attackers to bypass authentication and functionality restrictions by manipulating client-side inputs. This combination of weaknesses enables attackers to bypass authentication mechanisms entirely, potentially gaining unauthorized access to sensitive data and system functions. The vulnerability is remotely exploitable without requiring any privileges or user interaction, increasing its risk profile. The CVSS v3.1 score of 7.3 reflects a high severity due to the network attack vector, low attack complexity, and impacts on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability poses a significant threat to organizations relying on Perfektive for critical operations. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation strategies.

For European organizations, this vulnerability could lead to unauthorized access to sensitive information, disruption of services, and potential compromise of business-critical functions managed through Perfektive. Given the product's use in various sectors, including possibly government, finance, and industrial control systems, exploitation could result in data breaches, operational downtime, and reputational damage. The ability to bypass authentication without user interaction or privileges increases the likelihood of automated attacks, which could rapidly affect multiple systems. Organizations in Europe with regulatory obligations under GDPR could face compliance issues and fines if personal data is exposed. The integrity and availability impacts also raise concerns for sectors requiring high reliability and security, such as healthcare and energy. The lack of known exploits currently provides a window for proactive defense, but the high severity score indicates that the threat should be treated with urgency.

1. Immediately implement server-side rate limiting and account lockout policies to restrict excessive authentication attempts, ensuring these controls cannot be bypassed via client-side manipulation. 2. Deploy multi-factor authentication (MFA) for all user accounts accessing Perfektive to add an additional layer of security beyond passwords. 3. Conduct thorough logging and monitoring of authentication attempts to detect and respond to brute force or anomalous activities promptly. 4. Isolate Perfektive systems within secure network segments and restrict access to trusted IP addresses where feasible. 5. Engage with Turkguven Software Technologies Inc. to obtain patches or updates as soon as they become available and plan for rapid deployment. 6. Educate system administrators and users about the risks of this vulnerability and the importance of strong credential management. 7. Consider deploying Web Application Firewalls (WAF) or Intrusion Prevention Systems (IPS) with rules tailored to detect and block brute force attempts targeting Perfektive. 8. Review and harden client-side code and configurations to minimize reliance on client-side enforcement of security controls. 9. Perform regular security assessments and penetration testing focused on authentication mechanisms within Perfektive environments.
