CVE-2025-13125 is an authorization bypass vulnerability classified under CWE-639 (Authorization Bypass Through User-Controlled Key) affecting the DijiDemi product developed by Im Park Information Technology, Electronics, Press, Publishing and Advertising, Education Ltd. Co. This vulnerability stems from the product's failure to properly validate or restrict user-controlled keys that are used as trusted identifiers within the system. An attacker who has some level of privileges (PR:L) can remotely exploit this flaw over the network (AV:N) without requiring user interaction (UI:N). By manipulating these keys, the attacker can bypass authorization mechanisms, potentially gaining access to resources or functions that should be restricted. The vulnerability impacts confidentiality to a limited degree (C:L) but does not affect integrity or availability (I:N, A:N). The CVSS vector indicates low attack complexity (AC:L), meaning exploitation does not require specialized conditions. The affected version is listed as '0', which likely indicates all current versions up to 28.11.2025 are vulnerable. No patches or known exploits are currently available, suggesting this is a newly disclosed issue. The affected product, DijiDemi, is used in sectors such as information technology, electronics, press, publishing, advertising, and education, indicating a diverse user base. The vulnerability’s exploitation could allow unauthorized access to sensitive information or restricted functions, undermining trust in the system’s authorization controls.

For European organizations, the impact of CVE-2025-13125 primarily concerns confidentiality breaches due to unauthorized access enabled by the authorization bypass. Organizations in publishing, education, advertising, and related IT sectors using DijiDemi could face exposure of sensitive data or unauthorized access to restricted resources. Although the vulnerability does not affect data integrity or system availability, unauthorized access could lead to information leakage or misuse of privileged functions. This may result in reputational damage, regulatory non-compliance (e.g., GDPR concerns), and potential financial losses. Since exploitation requires some privileges, insider threats or compromised accounts could be leveraged to escalate access. The lack of patches increases the window of exposure, especially if attackers develop exploits. European entities relying on DijiDemi for critical operations should prioritize risk assessment and monitoring to detect suspicious activities related to authorization bypass attempts.

1. Implement strict validation and sanitization of all user-controlled keys used as trusted identifiers within DijiDemi to prevent manipulation. 2. Enforce the principle of least privilege rigorously, ensuring users have only the minimum necessary permissions to reduce the risk of privilege abuse. 3. Monitor logs and access patterns for unusual authorization requests or key usage anomalies that could indicate exploitation attempts. 4. Segregate sensitive functions and data within the application to limit the impact of any authorization bypass. 5. Engage with the vendor for timely patches or updates addressing this vulnerability and apply them as soon as available. 6. Conduct internal security reviews and penetration tests focusing on authorization mechanisms to identify similar weaknesses. 7. Educate administrators and users about the risks of privilege misuse and the importance of credential security. 8. Consider deploying Web Application Firewalls (WAFs) or similar controls to detect and block suspicious requests targeting authorization logic.
