CVE-2022-42245 is a critical SQL Injection vulnerability affecting Dreamer CMS version 4.0.01. SQL Injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly included in SQL queries, allowing an attacker to manipulate the database queries executed by the application. This vulnerability enables an unauthenticated attacker to execute arbitrary SQL commands remotely without any user interaction, due to its network attack vector (AV:N), low attack complexity (AC:L), and no privileges required (PR:N). The vulnerability impacts confidentiality, integrity, and availability of the affected system, as the attacker can exfiltrate sensitive data, modify or delete database contents, or disrupt service availability. The CVSS v3.1 base score of 9.8 reflects the critical nature of this flaw, with high impact on all three security properties (C:H/I:H/A:H). Although no known exploits have been reported in the wild yet, the ease of exploitation and severity make it a significant threat. The lack of vendor or product-specific details beyond Dreamer CMS 4.0.01 limits precise technical mitigation guidance, but the vulnerability is typical of improper input validation in web applications relying on SQL databases.

European organizations using Dreamer CMS 4.0.01 face severe risks from this vulnerability. Attackers could gain unauthorized access to sensitive data such as customer information, intellectual property, or internal business data, leading to data breaches and regulatory non-compliance under GDPR. Integrity violations could result in data tampering, undermining trust and operational accuracy. Availability impacts could disrupt business continuity, especially for organizations relying on Dreamer CMS for public-facing websites or internal portals. The critical severity and remote exploitability without authentication mean that attackers can launch automated attacks at scale, increasing the likelihood of compromise. Sectors such as government, finance, healthcare, and e-commerce in Europe are particularly vulnerable due to their reliance on content management systems and the high value of their data. The absence of known patches or vendor advisories further exacerbates the risk, potentially leaving organizations exposed for extended periods.

1. Immediate mitigation should include restricting public access to Dreamer CMS instances where feasible, such as through IP whitelisting or VPN access, to reduce exposure. 2. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection payloads targeting Dreamer CMS endpoints. 3. Conduct thorough input validation and parameterized queries in the CMS codebase if source code access is available, to eliminate the root cause of SQL Injection. 4. Monitor logs for unusual database query patterns or error messages indicative of injection attempts. 5. If possible, isolate the CMS database with strict access controls and least privilege principles to limit the impact of a successful injection. 6. Engage with the CMS vendor or community to obtain or develop patches and apply them promptly once available. 7. Perform regular security assessments and penetration testing focused on injection vulnerabilities. 8. Educate development and operations teams about secure coding practices and the risks of SQL Injection to prevent future occurrences.
