CVE-2024-0729 is a SQL Injection vulnerability identified in the ForU CMS product, specifically affecting versions up to 2020-06-23. The vulnerability resides in the cms_admin.php file, where the argument 'a_name' is improperly sanitized, allowing an attacker to inject malicious SQL code. This flaw is classified under CWE-89, which pertains to improper neutralization of special elements used in an SQL command. The vulnerability has a CVSS v3.1 base score of 5.5, indicating a medium severity level. The attack vector is adjacent network (AV:A), requiring low attack complexity (AC:L) and low privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), and the impact affects confidentiality, integrity, and availability at a low level (C:L/I:L/A:L). Although the exploit has been publicly disclosed, there are no known exploits in the wild at this time. The vulnerability allows an attacker with some level of authenticated access to manipulate the 'a_name' parameter to execute arbitrary SQL commands, potentially leading to unauthorized data access, data modification, or denial of service. Since the vulnerability is in an administrative script, it is likely that the attacker needs at least limited privileges within the CMS environment to exploit it. The lack of a patch link suggests that a fix may not yet be publicly available or that users must rely on vendor communication for remediation.

For European organizations using ForU CMS, this vulnerability poses a risk of unauthorized data exposure, data tampering, or service disruption within their content management systems. Given that the vulnerability requires low privileges but some level of authentication, insider threats or compromised low-privilege accounts could be leveraged to exploit this flaw. The impact on confidentiality could lead to leakage of sensitive business or customer information, while integrity and availability impacts could disrupt web services or corrupt stored data. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, could face compliance violations and reputational damage if exploited. The medium CVSS score reflects a moderate risk, but the critical classification by the original source suggests that in specific contexts, such as high-value targets or poorly segmented networks, the impact could be more severe. The absence of known active exploits reduces immediate risk but does not eliminate the threat, especially as public exploit code availability can accelerate attack development.

European organizations should immediately audit their ForU CMS installations to identify affected versions (up to 2020-06-23). Since no official patch link is provided, organizations should contact the vendor for guidance and monitor for official patches or updates. In the interim, applying strict access controls to the CMS administrative interface is critical, including enforcing strong authentication mechanisms and limiting administrative access to trusted IP ranges. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'a_name' parameter can provide additional protection. Regularly reviewing CMS logs for suspicious activity related to SQL injection attempts is advised. Organizations should also consider isolating the CMS environment from other critical systems to limit potential lateral movement. Finally, updating to a newer, supported CMS version once a patch is available is essential to fully remediate the vulnerability.
