CVE-2025-13129 identifies a vulnerability in the Onaylarım product by Seneka Software Hardware Information Technology Trade Contracting and Industry Ltd. Co., categorized under CWE-841: Improper Enforcement of Behavioral Workflow. This vulnerability arises when the software fails to properly enforce the intended sequence or conditions of operations within its workflow, allowing authorized users with low privileges to misuse functionality beyond their intended scope. The affected versions include 25.09.26.01, with the vulnerability published on December 1, 2025. The CVSS v3.1 base score is 4.3 (medium), with vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, indicating network exploitable, low attack complexity, requiring privileges, no user interaction, unchanged scope, no confidentiality or availability impact, but partial integrity impact. The vulnerability does not currently have known exploits in the wild, and no patches have been released yet. Improper enforcement of behavioral workflow can lead to functionality misuse, such as bypassing certain process steps or executing unauthorized actions within the application, potentially undermining data integrity or business process correctness. Since the flaw requires low privileges but no user interaction, an attacker with some level of access could exploit it remotely over the network. The lack of confidentiality and availability impact suggests that sensitive data exposure or service disruption is unlikely, but integrity violations could affect trustworthiness of operations or records managed by Onaylarım.

For European organizations, the primary impact of this vulnerability lies in the potential misuse of application functionality leading to integrity breaches. Organizations relying on Onaylarım for critical workflow management, contract approvals, or industrial processes may experience unauthorized modifications or bypassing of controls, which could result in financial discrepancies, compliance violations, or operational errors. Although confidentiality and availability are not directly affected, integrity compromises can undermine trust in automated processes and data accuracy. The requirement for low privileges means insider threats or compromised accounts could exploit this vulnerability. The absence of known exploits reduces immediate risk, but the lack of patches necessitates caution. Industries such as manufacturing, trade contracting, and hardware information technology sectors using Onaylarım in Europe should be particularly vigilant. The impact is moderate but could escalate if combined with other vulnerabilities or social engineering attacks.

To mitigate CVE-2025-13129, European organizations should first conduct a thorough review of user privileges within Onaylarım, ensuring the principle of least privilege is strictly enforced. Implement role-based access controls to limit functionality accessible to low-privilege users. Monitor workflow activities and audit logs for unusual or unauthorized actions that may indicate exploitation attempts. Employ network segmentation to restrict access to the Onaylarım system only to trusted users and systems. Since no patches are currently available, liaise with Seneka Software for updates or workarounds. Consider implementing compensating controls such as multi-factor authentication to reduce risk from compromised credentials. Train staff to recognize potential misuse scenarios and establish incident response plans tailored to workflow integrity issues. Regularly update and test backup and recovery procedures to maintain data integrity in case of exploitation. Finally, keep abreast of vendor advisories and apply patches promptly once released.
