CVE-2025-10397 is a server-side request forgery (SSRF) vulnerability identified in Magicblack MacCMS version 2025.1000.4050. The vulnerability arises from improper validation or sanitization of the 'cjurl' parameter within the API Handler component of the MacCMS product. An attacker can remotely manipulate this parameter to coerce the server into making unauthorized HTTP requests to arbitrary internal or external resources. SSRF vulnerabilities enable attackers to bypass network access controls, potentially accessing internal services, sensitive data, or performing further attacks such as port scanning or exploiting other internal vulnerabilities. The vulnerability does not require user interaction and can be triggered remotely without authentication, increasing its risk profile. Although the CVSS 4.0 score is 5.1 (medium severity), the presence of a public exploit increases the urgency for remediation. The vulnerability impacts confidentiality, integrity, and availability to a limited extent due to the low complexity of exploitation and the potential to access internal network resources. However, the requirement for some privileges (PR:H) reduces the ease of exploitation somewhat. No official patch links are currently available, and no known exploits in the wild have been reported yet. Given the nature of MacCMS as a content management system, exploitation could lead to unauthorized internal network reconnaissance, data exposure, or pivoting to more severe attacks within affected environments.

For European organizations using Magicblack MacCMS 2025.1000.4050, this SSRF vulnerability presents a moderate risk. Organizations operating web services or intranet applications behind the CMS could have their internal networks exposed to attackers, leading to potential data leakage or lateral movement within corporate networks. This is particularly concerning for sectors with sensitive data such as finance, healthcare, and government agencies. The ability to initiate requests from the server side could allow attackers to access internal APIs, cloud metadata services, or other protected resources, potentially compromising confidentiality and integrity. Additionally, SSRF can be a stepping stone for more complex attacks, including remote code execution or denial of service if combined with other vulnerabilities. The medium severity rating suggests that while immediate catastrophic impact is unlikely, the vulnerability should be addressed promptly to prevent exploitation, especially given the availability of public exploits. European organizations with stringent data protection regulations (e.g., GDPR) must consider the compliance implications of potential data breaches resulting from this vulnerability.

1. Immediate mitigation should focus on restricting access to the vulnerable API Handler component by implementing network-level controls such as firewall rules or web application firewalls (WAF) that can detect and block suspicious SSRF patterns targeting the 'cjurl' parameter. 2. Validate and sanitize all user-supplied input rigorously, especially the 'cjurl' parameter, enforcing strict allowlists of permissible URLs or domains to prevent arbitrary request redirection. 3. Employ network segmentation to isolate the CMS server from sensitive internal services and metadata endpoints, minimizing the impact of SSRF exploitation. 4. Monitor server logs and network traffic for unusual outbound requests originating from the CMS server, which may indicate exploitation attempts. 5. Engage with Magicblack for official patches or updates and apply them promptly once available. 6. Consider deploying runtime application self-protection (RASP) solutions to detect and block SSRF attacks in real time. 7. Conduct regular security assessments and penetration testing focused on SSRF and related vulnerabilities to identify and remediate weaknesses proactively.
