CVE-2025-13506 is a vulnerability classified under CWE-250 (Execution with Unnecessary Privileges) and CWE-269 (Improper Privilege Management) affecting Nebim Neyir Computer Industry and Services Inc.'s Nebim V3 ERP software versions starting from 2.0.59 up to but not including 3.0.1. The flaw arises from the ERP system executing certain operations with elevated privileges unnecessarily, which can be exploited by an attacker who has limited database access privileges. By leveraging this vulnerability, the attacker can escalate their privileges beyond the intended scope, gaining expanded control over the operating system hosting the ERP. This could allow unauthorized access to sensitive business data, modification or deletion of critical information, and potentially full system compromise. The vulnerability is remotely exploitable over the network (AV:N), requires low attack complexity (AC:L), and only requires privileges at a limited level (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component but with high confidentiality, integrity, and availability impacts (C:H/I:H/A:H). The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls. The vulnerability was reserved on 2025-11-21 and published on 2025-12-12 by TR-CERT, indicating a recent disclosure. No known exploits have been reported in the wild yet, but the high CVSS score suggests that exploitation could lead to severe consequences.

For European organizations, especially those in manufacturing, retail, and service industries relying on Nebim V3 ERP, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized access to sensitive corporate data, disruption of business operations, and potential regulatory compliance violations under GDPR due to data breaches. The ability to escalate privileges to the operating system level means attackers could deploy ransomware, steal intellectual property, or manipulate financial records. Given the ERP's role in managing critical business processes, availability impacts could cause operational downtime, affecting supply chains and customer service. The high severity and network exploitability make this a prime target for threat actors aiming to gain footholds in enterprise environments. European entities with interconnected ERP systems and insufficient network segmentation are particularly vulnerable to lateral movement and broader compromise.

Immediate mitigation should focus on restricting access to the Nebim V3 ERP database and application interfaces to only trusted and necessary personnel and systems. Network segmentation and firewall rules should be enforced to limit exposure of the ERP system to untrusted networks. Implement strict role-based access controls (RBAC) within the ERP to minimize privileges granted to users and services. Monitor logs for unusual database queries or privilege escalations. Since no patches are currently available, consider deploying application-layer firewalls or intrusion prevention systems (IPS) with custom rules to detect and block suspicious activity related to privilege escalation attempts. Conduct thorough security audits of ERP configurations and database permissions. Prepare incident response plans specifically addressing potential exploitation scenarios. Engage with the vendor for timely updates and patches, and plan for rapid deployment once available. Additionally, ensure backups of critical data are current and tested to enable recovery in case of compromise.
