CVE-2025-10912 is an authorization bypass vulnerability classified under CWE-639 (Authorization Bypass Through User-Controlled Key) affecting the TemizlikYolda product by Saastech Cleaning and Internet Services Inc. The vulnerability stems from the product's failure to properly validate or restrict user-controlled keys that influence authorization decisions. This allows an attacker with network access and low privileges to manipulate these keys to bypass intended authorization checks, potentially performing unauthorized actions. The vulnerability affects all versions up to 11022026, with no patch currently available and no vendor response to disclosure. The CVSS 3.1 base score is 5.4, reflecting a medium severity level due to the ease of exploitation (network accessible, low complexity), the requirement for some privileges (PR:L), and the impact on integrity and availability but not confidentiality. The flaw does not require user interaction and affects the product's security boundary, potentially allowing attackers to alter or disrupt services or data integrity. Although no known exploits are reported in the wild, the lack of vendor engagement increases risk. The vulnerability highlights the critical need for robust authorization mechanisms that do not rely on user-controllable inputs for security decisions.

For European organizations, this vulnerability poses a moderate risk primarily to the integrity and availability of services provided by TemizlikYolda. Attackers exploiting this flaw could perform unauthorized operations, potentially disrupting cleaning service workflows or manipulating data, which could degrade service quality or availability. Organizations relying on TemizlikYolda for operational management may face operational disruptions or data integrity issues, impacting business continuity. The absence of confidentiality impact reduces the risk of data leakage, but integrity and availability impacts can still cause significant operational and reputational damage. The medium CVSS score suggests that while the vulnerability is not critical, it is exploitable remotely with low privileges, increasing the attack surface. European entities in sectors where TemizlikYolda is used (e.g., facility management, cleaning services) should be particularly vigilant. The lack of vendor response and patch availability means organizations must rely on internal controls and monitoring to mitigate risk until a fix is released.

1. Implement strict validation and sanitization of all user-controlled keys or inputs that influence authorization decisions within TemizlikYolda configurations or integrations. 2. Enforce the principle of least privilege rigorously, ensuring users have only the minimum necessary permissions to reduce the impact of potential exploitation. 3. Deploy network segmentation and access controls to limit exposure of TemizlikYolda services to trusted internal networks or VPNs, reducing the attack surface. 4. Monitor logs and audit trails for unusual or unauthorized actions that could indicate exploitation attempts, focusing on anomalies in authorization-related activities. 5. Use Web Application Firewalls (WAFs) or Intrusion Detection/Prevention Systems (IDS/IPS) to detect and block suspicious requests targeting authorization mechanisms. 6. Prepare incident response plans specifically addressing potential abuse of authorization bypass vulnerabilities. 7. Engage with Saastech Cleaning and Internet Services Inc. for updates and patches, and consider vendor alternatives if no remediation is forthcoming. 8. Where possible, apply compensating controls such as multi-factor authentication or additional verification steps for sensitive operations within TemizlikYolda. 9. Conduct regular security assessments and penetration testing focused on authorization controls to identify and remediate weaknesses proactively.
