CVE-2025-29083 is a SQL Injection vulnerability identified in CSZ-CMS version 1.3.0, specifically within the execSqlFile function located in the Plugin_Manager.php file. This vulnerability allows a remote attacker to inject malicious SQL commands due to insufficient input sanitization or improper handling of SQL queries in the affected function. Exploitation of this flaw can lead to arbitrary code execution on the server hosting the CMS. The vulnerability is categorized under CWE-77, which relates to improper neutralization of special elements used in a command ('Command Injection'). The CVSS v3.1 base score is 6.5, indicating a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact affects confidentiality and integrity but not availability, as indicated by the CVSS vector (C:L/I:L/A:N). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in March 2025 and published in September 2025, suggesting recent discovery and disclosure. The lack of affected version details beyond 1.3.0 implies that this version is confirmed vulnerable, but it is unclear if other versions are impacted. The vulnerability allows attackers to execute arbitrary code remotely, which could lead to unauthorized data access or modification, potentially compromising the CMS and any connected systems or data repositories.

For European organizations using CSZ-CMS version 1.3.0, this vulnerability poses a significant risk to the confidentiality and integrity of their data. Attackers exploiting this flaw could gain unauthorized access to sensitive information, modify content, or execute arbitrary commands on the server, potentially leading to data breaches or defacement of websites. Given that CSZ-CMS is a content management system, organizations relying on it for public-facing websites or internal portals could face reputational damage, regulatory non-compliance (especially under GDPR), and operational disruptions. The medium severity score reflects that while availability is not directly impacted, the compromise of data integrity and confidentiality can have serious consequences. European entities in sectors such as government, finance, healthcare, and education, which often use CMS platforms, may be particularly vulnerable if they have not updated or patched their systems. The absence of known exploits in the wild provides a window for proactive mitigation, but the ease of exploitation (no privileges or user interaction required) means attackers could quickly develop exploits once details are public.

European organizations should immediately audit their infrastructure to identify any deployments of CSZ-CMS version 1.3.0. In the absence of an official patch, organizations should consider the following specific mitigations: 1) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the execSqlFile function. 2) Restrict network access to the CMS management interfaces to trusted IP addresses only. 3) Conduct code reviews or apply temporary input validation and sanitization around the execSqlFile function to neutralize potentially malicious inputs. 4) Monitor logs closely for unusual SQL queries or error messages indicative of injection attempts. 5) Plan for an upgrade or patch deployment as soon as a fix becomes available from the vendor. 6) Employ database-level protections such as least privilege principles for the CMS database user to limit the impact of any successful injection. 7) Educate development and IT teams about this vulnerability to ensure rapid response and awareness. These steps go beyond generic advice by focusing on immediate containment and risk reduction until a vendor patch is released.
