CVE-2024-58308 is a critical SQL injection vulnerability identified in Quick.CMS version 6.7, a content management system developed by opensolution. The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), specifically within the login authentication mechanism. Attackers can exploit this flaw by injecting crafted SQL payloads such as ' or '1'='1 into the login form, which manipulates the underlying SQL query logic to bypass authentication controls. This attack requires no authentication, no user interaction, and can be executed remotely over the network, making it highly accessible to attackers. The vulnerability impacts the confidentiality and integrity of the system by granting unauthorized administrative access, potentially allowing attackers to modify content, steal sensitive data, or further compromise the hosting environment. The CVSS 4.0 base score of 9.3 reflects the high impact and ease of exploitation, with attack vector being network-based and no privileges or user interaction required. Although no public exploits have been reported yet, the vulnerability's nature and severity suggest it is likely to be targeted soon. Quick.CMS is used by various organizations for website management, and version 6.7 is specifically affected. The lack of available patches at the time of disclosure increases the urgency for organizations to apply mitigations such as input sanitization, use of prepared statements, or temporary access restrictions. Monitoring for suspicious login attempts and anomalous database queries is also recommended to detect exploitation attempts.

For European organizations, the impact of CVE-2024-58308 can be significant. Unauthorized administrative access to Quick.CMS-powered websites can lead to data breaches involving personal data protected under GDPR, defacement of public-facing websites, and disruption of business operations. Attackers gaining admin privileges can implant malware, redirect users to malicious sites, or exfiltrate sensitive information. Organizations in sectors such as government, finance, healthcare, and media that rely on Quick.CMS for content management face heightened risks due to the potential exposure of critical or sensitive information. The breach of confidentiality and integrity can damage organizational reputation, incur regulatory penalties, and result in financial losses. Additionally, compromised CMS platforms can serve as footholds for further lateral movement within corporate networks, increasing the overall security risk. The vulnerability’s ease of exploitation and lack of authentication requirements make it a particularly attractive target for opportunistic attackers and advanced persistent threat actors alike.

1. Immediate upgrade to a patched version of Quick.CMS once available from the vendor. 2. Until patches are released, implement web application firewall (WAF) rules to detect and block SQL injection payloads targeting the login form. 3. Apply strict input validation and sanitization on all user inputs, especially login fields, to neutralize special SQL characters. 4. Refactor the authentication code to use parameterized queries or prepared statements to prevent SQL injection. 5. Restrict administrative access by IP whitelisting or VPN-only access where feasible. 6. Monitor web server and database logs for unusual login attempts or SQL errors indicative of injection attempts. 7. Conduct penetration testing focused on authentication bypass and injection vectors to verify mitigations. 8. Educate development teams on secure coding practices to prevent similar vulnerabilities in future releases. 9. Maintain regular backups of CMS data and configurations to enable rapid recovery if compromise occurs. 10. Implement multi-factor authentication (MFA) on administrative accounts to add an additional layer of security.
