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 the Perfektive software by Turkguven Software Technologies Inc. The core issue is that the product fails to properly restrict the number of authentication attempts, allowing attackers to perform brute force attacks to guess credentials. Additionally, the software improperly relies on client-side controls to enforce security policies that should be enforced on the server side, making it possible for attackers to bypass these controls by manipulating client inputs. The reliance on untrusted inputs for critical security decisions further exacerbates the risk, enabling authentication bypass and functionality bypass. The vulnerability affects all versions before 12574 Build 2701 and does not require any privileges or user interaction to exploit, making it remotely exploitable over the network. The CVSS 3.1 score of 7.3 reflects a high severity due to the potential impact on confidentiality, integrity, and availability of systems using Perfektive. Although no known exploits are reported in the wild, the vulnerability poses a significant risk if weaponized. The absence of patch links indicates that a fix may not yet be publicly available, emphasizing the need for immediate mitigation measures. The vulnerability's exploitation could lead to unauthorized access, data leakage, and disruption of services, particularly in environments where Perfektive is used for critical operations or sensitive data management.

For European organizations, the impact of CVE-2025-10161 can be substantial, especially for those relying on Perfektive for authentication and access control in critical business applications. Successful exploitation could lead to unauthorized access to sensitive data, manipulation of business processes, and potential service disruptions. This could affect confidentiality by exposing user credentials and sensitive information, integrity by allowing attackers to bypass security controls and alter data or functionality, and availability by enabling denial of service through repeated authentication attempts or bypassing critical functions. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that use Perfektive are particularly at risk. The vulnerability's remote exploitability without authentication or user interaction increases the likelihood of automated attacks and large-scale brute force campaigns. This could result in regulatory compliance violations under GDPR and other European data protection laws, leading to legal and financial repercussions. The lack of a current patch means organizations must rely on compensating controls to reduce exposure until an official fix is released.

1. Implement strict server-side rate limiting on authentication endpoints to prevent brute force attempts, regardless of client-side controls. 2. Enforce multi-factor authentication (MFA) to add an additional layer of security beyond passwords. 3. Monitor and analyze authentication logs for unusual patterns indicative of brute force or bypass attempts. 4. Disable or restrict access to Perfektive interfaces from untrusted networks or IP ranges using network segmentation and firewall rules. 5. Validate all inputs on the server side rigorously to prevent reliance on untrusted client data for security decisions. 6. Engage with Turkguven Software Technologies Inc. to obtain information on patches or updates and apply them promptly once available. 7. Conduct internal security assessments and penetration testing focused on authentication mechanisms within Perfektive. 8. Educate users and administrators about the risks of weak passwords and the importance of secure authentication practices. 9. Prepare incident response plans specifically addressing potential exploitation of authentication bypass vulnerabilities. 10. Consider temporary compensating controls such as account lockout policies and CAPTCHA challenges on login forms until patches are deployed.
