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 arises due to improper neutralization of special characters 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 input fields. This injection manipulates the underlying SQL query logic, effectively bypassing authentication checks without requiring any credentials, privileges, or user interaction. The vulnerability is remotely exploitable over the network (AV:N), with low attack complexity (AC:L), no authentication required (AT:N), and no user interaction needed (UI:N). The impact on confidentiality and integrity is high (VC:H, VI:H), as attackers gain unauthorized administrative access, potentially allowing full control over the CMS, data exfiltration, content manipulation, or further lateral movement within the network. The vulnerability does not affect availability directly and has no scope change or privileges required. Currently, no patches or fixes have been published by the vendor, and no known exploits have been observed in the wild. The vulnerability was published on December 11, 2025, and is tracked under CVE-2024-58308 with a CVSS v4.0 score of 9.3, categorizing it as critical. This flaw represents a significant threat to organizations relying on Quick.CMS 6.7 for website management and content delivery, especially those with sensitive or critical data hosted on these platforms.

For European organizations, this vulnerability poses a severe risk to the confidentiality and integrity of their web platforms managed by Quick.CMS 6.7. Successful exploitation allows attackers to bypass authentication and gain administrative privileges, enabling unauthorized access to sensitive data, modification or deletion of content, and potential deployment of further malicious payloads. This can lead to data breaches, reputational damage, regulatory non-compliance (e.g., GDPR violations), and operational disruptions. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that use Quick.CMS are particularly vulnerable. The lack of authentication and user interaction requirements means attacks can be automated and executed at scale, increasing the likelihood of widespread compromise. Additionally, attackers could leverage compromised CMS instances to launch phishing campaigns, distribute malware, or pivot into internal networks, amplifying the overall impact.

1. Immediately restrict external access to the Quick.CMS login interface using network segmentation, IP whitelisting, or VPN access to reduce exposure. 2. Deploy a Web Application Firewall (WAF) with specific SQL injection detection and prevention rules tailored to Quick.CMS login parameters to block malicious payloads. 3. Monitor authentication logs for unusual login attempts or patterns indicative of SQL injection attacks, and implement alerting mechanisms. 4. Conduct a thorough security audit of all Quick.CMS instances to identify and isolate vulnerable versions. 5. Engage with the vendor or community to obtain patches or updates as soon as they become available and prioritize timely application. 6. Consider implementing multi-factor authentication (MFA) on administrative accounts to add an additional security layer, mitigating unauthorized access even if authentication is bypassed. 7. Educate administrators and developers on secure coding practices to prevent similar injection flaws in custom modules or extensions. 8. Regularly back up CMS data and configurations to enable rapid recovery in case of compromise.
