CVE-2025-7102 is a SQL Injection vulnerability identified in BoyunCMS versions up to 1.4.20. The vulnerability resides in the file application/update/controller/Server.php, specifically in the handling of the 'phone' argument. An attacker can remotely manipulate this argument to inject malicious SQL code, potentially compromising the underlying database. The vulnerability requires no user interaction and no authentication, making it accessible to unauthenticated remote attackers. The CVSS 4.0 score is 5.3 (medium severity), reflecting that while the attack vector is network-based with low attack complexity, it requires low privileges and has limited impact on confidentiality, integrity, and availability. The vulnerability has been publicly disclosed, but no known exploits are currently reported in the wild. The lack of a patch link suggests that a fix may not yet be available or publicly released. SQL Injection vulnerabilities typically allow attackers to read, modify, or delete database contents, which can lead to data leakage, data corruption, or denial of service. Given the affected versions span a wide range (1.4.0 through 1.4.20), many deployments using these versions are at risk if not updated or mitigated. The vulnerability's presence in a CMS platform like BoyunCMS, which is used for content management, increases the risk of website defacement, data theft, or further pivoting into internal networks if exploited successfully.

For European organizations using BoyunCMS, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Exploitation could lead to unauthorized access to sensitive customer or business data stored in the CMS database. This could result in data breaches subject to GDPR regulations, leading to legal and financial penalties. Additionally, attackers could modify website content or inject malicious code, damaging brand reputation and trust. The remote and unauthenticated nature of the vulnerability increases the likelihood of exploitation, especially if organizations have not applied mitigations or updates. The medium CVSS score suggests that while the impact is not critical, the ease of exploitation and potential data exposure make it a notable threat. Organizations in sectors such as e-commerce, government, healthcare, and media that rely on BoyunCMS for their web presence are particularly vulnerable. The lack of known exploits in the wild currently provides a window for proactive defense, but the public disclosure increases the risk of future exploitation attempts.

1. Immediate mitigation should include restricting access to the vulnerable endpoint (application/update/controller/Server.php) via web application firewalls (WAFs) or network-level controls to limit exposure. 2. Implement input validation and parameterized queries or prepared statements in the affected code to prevent SQL injection. Since no patch link is provided, organizations should contact BoyunCMS vendors or monitor official channels for security updates and apply patches as soon as they become available. 3. Conduct thorough code audits of custom BoyunCMS deployments to identify and remediate similar injection points. 4. Enable detailed logging and monitoring of database queries and web requests to detect suspicious activity indicative of exploitation attempts. 5. Employ database user accounts with the least privileges necessary to limit the impact of any successful injection. 6. Regularly back up CMS data and test restoration procedures to minimize downtime and data loss in case of compromise. 7. Educate development and operations teams about secure coding practices and the risks of SQL injection vulnerabilities.
