CVE-2025-0616 is a high-severity SQL Injection vulnerability (CWE-89) found in the B2B - Netsis Panel developed by Teknolojik Center Telecommunication Industry Trade Co. Ltd. This vulnerability arises due to improper neutralization of special elements in SQL commands, allowing an unauthenticated attacker to inject malicious SQL code remotely over the network (AV:N, AC:L, PR:N, UI:N). The vulnerability affects versions of the B2B - Netsis Panel up to the version released on or before 2025-10-03. Exploitation does not require any user interaction or privileges, making it highly accessible to attackers. The CVSS 3.1 base score is 8.2, reflecting a high impact on confidentiality (C:H), with limited impact on integrity (I:L) and no impact on availability (A:N). An attacker could leverage this flaw to extract sensitive data from the backend database, potentially exposing confidential business information, customer data, or credentials. Although no known exploits are currently reported in the wild, the ease of exploitation and the critical nature of the data handled by B2B platforms make this a significant threat. The lack of available patches at the time of publication increases the urgency for mitigation. The vulnerability is particularly concerning for organizations relying on the Netsis Panel for B2B operations, as SQL Injection can lead to data breaches, unauthorized data disclosure, and potential downstream attacks such as privilege escalation or lateral movement within the network.

For European organizations using the B2B - Netsis Panel, this vulnerability poses a serious risk to the confidentiality of sensitive business and customer data. The exposure of such data could lead to regulatory non-compliance under GDPR, resulting in substantial fines and reputational damage. Given the B2B nature of the product, compromised data could include trade secrets, financial information, and partner credentials, potentially disrupting supply chains and business relationships. Additionally, attackers could use the vulnerability as a foothold to conduct further attacks within the corporate network, increasing the risk of broader compromise. The absence of authentication requirements and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation. The impact is heightened for sectors with stringent data protection requirements such as finance, healthcare, and telecommunications. Furthermore, data breaches could trigger mandatory breach notifications to European data protection authorities, amplifying operational and legal consequences.

European organizations should immediately conduct a thorough security assessment of their Netsis Panel deployments. Specific mitigation steps include: 1) Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection payloads targeting the Netsis Panel endpoints. 2) Employing strict input validation and parameterized queries or prepared statements in any custom integrations or extensions of the Netsis Panel to prevent injection vectors. 3) Monitoring database query logs and application logs for anomalous or suspicious SQL queries indicative of injection attempts. 4) Restricting database user permissions to the minimum necessary to limit the impact of a successful injection. 5) Isolating the Netsis Panel environment within segmented network zones to reduce lateral movement risk. 6) Engaging with Teknolojik Center Telecommunication Industry Trade Co. Ltd. for timely patch releases and applying them promptly once available. 7) Conducting regular penetration testing focused on injection vulnerabilities to proactively identify weaknesses. 8) Educating IT and security teams about this vulnerability and ensuring incident response plans include scenarios involving SQL Injection attacks on critical B2B platforms.
