CVE-2023-53975 identifies a critical SQL injection vulnerability in thedigicraft Atom CMS version 2.0. The vulnerability arises from improper neutralization of special elements in SQL commands, specifically through the 'id' parameter on the admin index page. Because this parameter is not properly validated or sanitized, remote attackers can inject arbitrary SQL code without requiring authentication or user interaction. The attack vector is network-based with low attack complexity, allowing exploitation by unauthenticated actors. The vulnerability enables time-based blind SQL injection, a technique where attackers infer database information by measuring response delays caused by injected SQL commands. This can lead to unauthorized disclosure of sensitive data, modification of database contents, or even full system compromise depending on the database privileges. The CVSS 4.0 score of 9.3 reflects the high impact on confidentiality and integrity, with no requirement for privileges or user interaction, and no scope change. Although no public exploits are currently known, the vulnerability's nature and ease of exploitation make it a significant threat. The lack of available patches or mitigations from the vendor increases the urgency for organizations to implement compensating controls. The vulnerability affects only version 2.0 of Atom CMS, so organizations running this version are at risk. Given the administrative context of the vulnerable parameter, exploitation could allow attackers to manipulate critical backend data or gain further access.

For European organizations, exploitation of CVE-2023-53975 could result in severe data breaches, including unauthorized access to sensitive customer, employee, or operational data stored in the CMS database. The integrity of website content and backend data could be compromised, potentially leading to misinformation, defacement, or disruption of services. Availability impact is limited but possible if attackers execute destructive SQL commands. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, face heightened legal and reputational risks. The unauthenticated nature of the vulnerability means attackers can exploit it remotely without credentials, increasing the attack surface. Given the critical CVSS score, successful exploitation could also facilitate lateral movement within networks if attackers leverage the CMS as a foothold. This threat could undermine trust in digital services and cause operational disruptions, especially for organizations relying on Atom CMS for content management and administrative functions.

1. Immediate upgrade: Check for any vendor patches or updates addressing CVE-2023-53975 and apply them promptly once available. 2. Input validation: Implement strict server-side input validation and sanitization for all parameters, especially the 'id' parameter on the admin index page, to block malicious SQL syntax. 3. Web Application Firewall (WAF): Deploy and configure a WAF with rules specifically targeting SQL injection patterns, including time-based blind injection techniques. 4. Access controls: Restrict access to the admin interface by IP whitelisting or VPN-only access to reduce exposure. 5. Database permissions: Enforce the principle of least privilege on database accounts used by the CMS to limit potential damage from injection attacks. 6. Monitoring and logging: Enable detailed logging of database queries and monitor for anomalies or unusual delays indicative of time-based SQL injection attempts. 7. Network segmentation: Isolate CMS servers from critical internal networks to contain potential breaches. 8. Incident response readiness: Prepare to respond quickly to any signs of exploitation, including forensic analysis and containment procedures. 9. Consider alternative CMS solutions if patches are unavailable or delayed to reduce long-term risk.
