CVE-2025-12927 is a SQL injection vulnerability identified in the DedeBIZ software versions 6.3.0 through 6.3.2. The flaw resides in an unspecified function within the /admin/archives_add.php file, where the manipulation of the flags[] parameter allows an attacker to inject malicious SQL code. This vulnerability can be exploited remotely without any user interaction, but it requires the attacker to have high privileges (PR:H), indicating that some form of authentication or elevated access is necessary before exploitation. The CVSS 4.0 vector indicates no user interaction (UI:N), low complexity (AC:L), and no privileges required for attack execution (AV:N), but the provided vector states PR:H, meaning privilege is required, which somewhat limits the attack surface. The impact on confidentiality, integrity, and availability is low individually but combined can lead to significant compromise of the backend database, including unauthorized data disclosure, data manipulation, or denial of service. Although no known exploits are currently active in the wild, the public disclosure of the exploit details increases the risk of future attacks. The vulnerability is particularly critical for organizations relying on DedeBIZ for administrative content management, as the affected file is part of the admin interface. The absence of official patches at the time of disclosure necessitates immediate mitigation steps to prevent exploitation.

For European organizations, this vulnerability poses a risk of unauthorized access to sensitive business data managed through DedeBIZ, potentially leading to data breaches, data integrity violations, and service disruptions. Since the vulnerability requires high privileges, the threat is more significant in environments where internal threat actors or compromised accounts exist. Exploitation could allow attackers to extract confidential information, modify records, or disrupt business operations, impacting compliance with GDPR and other data protection regulations. The medium severity rating suggests moderate risk, but the public availability of exploit details could lead to targeted attacks against organizations using DedeBIZ, especially in sectors like e-commerce, media, or government agencies that rely on this platform for content and business management.

1. Immediately restrict access to the /admin/archives_add.php endpoint to trusted IP addresses or VPN users only. 2. Implement a web application firewall (WAF) with rules specifically designed to detect and block SQL injection attempts targeting the flags[] parameter. 3. Enforce strict authentication and authorization controls to limit high privilege access to the admin interface. 4. Monitor database logs and application logs for unusual queries or error messages indicative of SQL injection attempts. 5. If possible, apply input validation and sanitization on the flags[] parameter within the application code to prevent injection. 6. Engage with DedeBIZ vendors or community to obtain or develop patches and apply them promptly once available. 7. Conduct regular security assessments and penetration testing focusing on injection vulnerabilities in administrative modules. 8. Educate administrators and developers about the risks and signs of SQL injection attacks to improve detection and response.
