CVE-2023-51052: n/a in n/a
S-CMS v5.0 was discovered to contain a SQL injection vulnerability via the A_formauth parameter at /admin/ajax.php.
AI Analysis
Technical Summary
CVE-2023-51052 is a critical SQL injection vulnerability identified in S-CMS version 5.0, specifically exploitable via the 'A_formauth' parameter in the /admin/ajax.php endpoint. SQL injection (CWE-89) vulnerabilities allow attackers to manipulate backend database queries by injecting malicious SQL code through unsanitized input parameters. In this case, the vulnerable parameter is part of an administrative AJAX interface, which likely handles authentication or authorization functions. The vulnerability has a CVSS 3.1 base score of 9.8, indicating a critical severity level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reveals that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability to a high degree. Exploiting this vulnerability could allow an unauthenticated attacker to execute arbitrary SQL commands on the backend database, potentially leading to full data disclosure, data manipulation, or complete system compromise. Although no known exploits are currently reported in the wild, the low complexity and lack of required privileges make it highly likely that exploit code will emerge rapidly. The absence of vendor or product details limits precise identification of affected deployments, but the vulnerability is tied to S-CMS, a content management system, which is often used by organizations to manage websites and internal portals. The vulnerability's presence in an administrative AJAX endpoint suggests that successful exploitation could grant attackers administrative-level access or control over the CMS and its underlying data stores. This type of vulnerability is a common and severe threat vector in web applications, especially those managing sensitive or business-critical information.
Potential Impact
For European organizations using S-CMS v5.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web applications and associated data. Exploitation could lead to unauthorized data disclosure, including sensitive customer or business information, data tampering, or complete service disruption. Given the administrative nature of the vulnerable endpoint, attackers might gain control over the CMS, enabling further lateral movement within the network or deployment of additional malware. This could result in reputational damage, regulatory penalties under GDPR due to data breaches, and operational downtime. Sectors such as government, finance, healthcare, and critical infrastructure in Europe that rely on S-CMS for web content management are particularly at risk. The vulnerability's ease of exploitation and remote attack vector increase the likelihood of automated scanning and exploitation attempts, potentially leading to widespread compromise if unpatched. The lack of known exploits currently provides a small window for proactive mitigation before active exploitation begins.
Mitigation Recommendations
1. Immediate patching or upgrading: Organizations should verify if a vendor patch or update for S-CMS v5.0 addressing CVE-2023-51052 is available and apply it promptly. If no official patch exists, consider disabling or restricting access to the /admin/ajax.php endpoint until a fix is released. 2. Input validation and parameter sanitization: Implement strict server-side input validation and use parameterized queries or prepared statements to prevent SQL injection. 3. Access controls: Restrict access to administrative AJAX endpoints by IP whitelisting, VPN-only access, or multi-factor authentication to reduce exposure. 4. Web Application Firewall (WAF): Deploy or update WAF rules to detect and block SQL injection attempts targeting the A_formauth parameter or /admin/ajax.php path. 5. Monitoring and logging: Enable detailed logging of web requests to detect anomalous or suspicious activity related to SQL injection attempts and conduct regular log reviews. 6. Incident response readiness: Prepare for potential exploitation by having an incident response plan that includes database integrity checks and backup restoration procedures. 7. Network segmentation: Isolate the CMS backend and database servers from general user networks to limit attacker lateral movement in case of compromise. 8. Vendor engagement: Engage with the CMS vendor or community to obtain timely updates and share threat intelligence.
