CVE-2025-29083 is a SQL Injection vulnerability identified in the CSZ-CMS content management system, specifically in version 1.3.0. The vulnerability exists in the execSqlFile function within the Plugin_Manager.php file. SQL Injection vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing an attacker to manipulate the database queries executed by the application. In this case, a remote attacker can exploit this flaw to execute arbitrary code on the affected system by injecting malicious SQL commands. This could lead to unauthorized data access, data modification, or even full system compromise depending on the privileges of the database user and the underlying system configuration. The vulnerability is remotely exploitable and does not require user interaction, increasing its risk profile. Although no CVSS score has been assigned yet and no known exploits are reported in the wild, the nature of the vulnerability indicates a significant security risk. The lack of patch information suggests that a fix may not yet be available, emphasizing the need for immediate attention from organizations using CSZ-CMS version 1.3.0.

For European organizations using CSZ-CMS version 1.3.0, this vulnerability poses a serious threat to the confidentiality, integrity, and availability of their web applications and underlying data. Exploitation could lead to unauthorized access to sensitive information, including personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, attackers could alter or delete critical data, disrupt services, or leverage the compromised system as a foothold for further attacks within the network. Given the remote exploitation capability without user interaction, the threat could be rapidly weaponized to target multiple organizations. This is particularly concerning for sectors such as government, finance, healthcare, and critical infrastructure in Europe, where data sensitivity and service continuity are paramount.

Organizations should immediately audit their use of CSZ-CMS to determine if version 1.3.0 or affected components are in use. If so, they should consider the following specific mitigations: 1) Temporarily disable or restrict access to the Plugin_Manager.php functionality, especially the execSqlFile function, until a patch is available. 2) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting this endpoint. 3) Conduct thorough input validation and sanitization on all user inputs interacting with database queries, applying parameterized queries or prepared statements where possible. 4) Monitor logs for unusual database query patterns or unexpected errors that could indicate exploitation attempts. 5) Engage with the CSZ-CMS vendor or community to obtain or expedite a security patch. 6) Isolate affected systems and apply network segmentation to limit lateral movement if compromise is suspected. 7) Prepare incident response plans tailored to SQL injection attacks to enable rapid containment and recovery.
