CVE-2025-3800 is a critical SQL injection vulnerability identified in version 11 of WCMS, a web content management system. The vulnerability resides in an unspecified functionality within the file app/controllers/AnonymousController.php. Specifically, it involves the manipulation of the 'mobile_phone' parameter, which is susceptible to SQL injection attacks. This type of injection allows an attacker to insert or manipulate SQL queries executed by the backend database, potentially leading to unauthorized data access, data modification, or even full system compromise. The vulnerability can be exploited remotely without authentication, increasing the attack surface significantly. Although the description highlights the 'mobile_phone' parameter, it also suggests that other parameters might be vulnerable, indicating a broader input validation issue within the affected controller. The exploit details have been publicly disclosed, which raises the risk of exploitation by threat actors. Despite the public disclosure, no known exploits are currently observed in the wild. The lack of vendor project information and absence of patch links suggest that a fix may not yet be available, or at least not publicly released. Given the critical nature of SQL injection vulnerabilities, especially those that can be exploited remotely and without authentication, this vulnerability poses a significant risk to any organization using WCMS version 11. Attackers could leverage this flaw to extract sensitive data, modify or delete content, escalate privileges, or pivot within the network, severely impacting confidentiality, integrity, and availability of affected systems.

For European organizations using WCMS version 11, this vulnerability could lead to severe consequences. The ability to perform SQL injection remotely without authentication means attackers can compromise websites or applications managed by WCMS, potentially exposing sensitive customer data, intellectual property, or internal communications. This could result in data breaches subject to GDPR penalties, reputational damage, and loss of customer trust. Furthermore, attackers might deface websites, disrupt services, or implant malicious code, affecting business continuity and operational integrity. Organizations in sectors such as finance, healthcare, government, and e-commerce—where WCMS might be used to manage public-facing or internal content—are particularly at risk. The public disclosure of the exploit increases the likelihood of opportunistic attacks, especially against organizations that have not yet applied mitigations or workarounds. The potential for lateral movement after initial compromise could further escalate the impact, threatening broader IT infrastructure beyond the WCMS itself.

Given the absence of an official patch, European organizations should immediately implement the following specific mitigations: 1) Conduct a thorough audit of all input parameters handled by app/controllers/AnonymousController.php, especially 'mobile_phone', to identify and sanitize inputs rigorously using parameterized queries or prepared statements to prevent SQL injection. 2) Employ Web Application Firewalls (WAFs) configured with custom rules to detect and block SQL injection patterns targeting the 'mobile_phone' parameter and other suspicious inputs. 3) Restrict remote access to the WCMS administration interfaces and limit exposure of vulnerable endpoints by network segmentation and IP whitelisting where feasible. 4) Monitor application logs and database query logs for anomalous or unexpected queries indicative of injection attempts. 5) If possible, temporarily disable or restrict the functionality related to the vulnerable controller until a patch is available. 6) Engage with the WCMS vendor or community to obtain updates or patches as soon as they are released. 7) Educate development and security teams about secure coding practices to prevent similar injection vulnerabilities in future releases. These targeted actions go beyond generic advice by focusing on the specific vulnerable component and parameters, enhancing detection, and limiting attack vectors.
