CVE-2025-29084 is a SQL Injection vulnerability identified in CSZ-CMS version 1.3.0. The flaw exists in the execSqlFile function within the Upgrade.php file. This vulnerability allows a remote attacker to inject malicious SQL commands without requiring authentication or user interaction. Exploiting this vulnerability could enable the attacker to execute arbitrary code on the underlying database or potentially the hosting server, depending on the database permissions and environment configuration. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), indicating that user-supplied input is not properly sanitized before being incorporated into SQL queries. The CVSS v3.1 base score is 6.5, indicating a medium severity level, with an attack vector of network (remote exploitation), low attack complexity, no privileges required, and no user interaction needed. The impact primarily affects confidentiality and integrity, as the attacker can manipulate database contents or extract sensitive data, but does not directly affect availability. No known exploits are currently reported in the wild, and no patches or mitigations have been officially published yet. Given the nature of the vulnerability, it poses a significant risk to any organization using the affected CSZ-CMS version, especially if the CMS is exposed to the internet without additional protective controls.

For European organizations using CSZ-CMS version 1.3.0, this vulnerability could lead to unauthorized access to sensitive data stored within the CMS database, including user credentials, personal data, or proprietary business information. The ability to execute arbitrary SQL commands remotely without authentication increases the risk of data breaches and potential compliance violations under GDPR, which mandates strict protection of personal data. Furthermore, attackers might leverage this vulnerability to escalate privileges or implant backdoors, leading to further compromise of internal systems. The integrity of website content and stored data could be undermined, damaging organizational reputation and trust. Since the vulnerability does not require user interaction or authentication, automated exploitation attempts could be widespread once the vulnerability becomes publicly known, increasing the risk for European entities with internet-facing CMS installations. The lack of an official patch means organizations must rely on interim mitigations, increasing operational risk until a fix is available.

European organizations should immediately audit their environments to identify any deployments of CSZ-CMS version 1.3.0. If found, they should consider temporarily disabling the Upgrade.php functionality or restricting access to this script via network controls such as web application firewalls (WAFs) or IP whitelisting. Input validation and sanitization should be enhanced at the application level if possible, to prevent injection of malicious SQL commands. Monitoring and logging of database queries and web server access should be intensified to detect anomalous activity indicative of exploitation attempts. Organizations should also prepare to apply patches or updates as soon as they become available from the vendor. In the interim, isolating the CMS environment from critical internal networks and enforcing the principle of least privilege on database accounts used by the CMS can reduce potential damage. Regular backups of CMS data should be maintained to enable recovery in case of data manipulation or loss. Finally, organizations should educate their security teams about this vulnerability to ensure rapid response to any suspicious activity.
