CVE-2025-10395 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Magicblack MacCMS product, specifically version 2025.1000.4050. The vulnerability resides in the 'col_url' function of the Scheduled Task Handler component. By manipulating the 'cjurl' argument, an attacker can cause the server to make unauthorized requests to internal or external resources. SSRF vulnerabilities allow attackers to abuse the server as a proxy to access or interact with internal systems that are otherwise inaccessible from the outside. This can lead to information disclosure, internal network scanning, or even further exploitation if the internal services are vulnerable. The vulnerability can be exploited remotely without user interaction and does not require authentication, which increases the attack surface. The CVSS 4.0 base score is 5.1 (medium severity), reflecting the moderate impact on confidentiality, integrity, and availability, with low complexity and no user interaction needed. However, the attack requires some level of privileges (PR:H), indicating that the attacker must have high privileges on the system to exploit this vulnerability. There are no known exploits in the wild yet, and no patches have been linked at the time of publication. The vulnerability does not involve scope changes or security controls bypass but has low impact on confidentiality, integrity, and availability. Given the nature of SSRF, the risk is primarily related to internal network reconnaissance and potential pivoting to other internal services.

For European organizations using Magicblack MacCMS version 2025.1000.4050, this SSRF vulnerability poses a moderate risk. If exploited, attackers with high privileges on the CMS server could leverage the vulnerability to access internal network resources, potentially bypassing firewalls and network segmentation. This could lead to unauthorized access to sensitive internal services, data leakage, or lateral movement within the organization's infrastructure. The impact is particularly relevant for organizations that host critical internal services behind the CMS server or use it as a gateway to other internal systems. Given the medium severity and the requirement for high privileges, the vulnerability is less likely to be exploited by external attackers without initial access. However, insider threats or attackers who have already compromised a user account with elevated privileges could use this vulnerability to escalate their access. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, should be cautious as internal data exposure could lead to regulatory penalties and reputational damage.

To mitigate CVE-2025-10395, European organizations should take the following specific actions: 1) Apply vendor patches or updates as soon as they become available for Magicblack MacCMS 2025.1000.4050. Since no patch links are currently provided, maintain close monitoring of vendor advisories. 2) Restrict and audit user privileges on the CMS server to minimize the number of accounts with high privileges, reducing the risk of exploitation. 3) Implement strict input validation and sanitization on the 'cjurl' parameter within the Scheduled Task Handler to prevent malicious URL injection. 4) Employ network segmentation and firewall rules to limit the CMS server's ability to initiate outbound requests to sensitive internal resources, effectively containing potential SSRF exploitation. 5) Monitor logs for unusual outbound requests originating from the CMS server, especially those targeting internal IP ranges or unexpected external endpoints. 6) Conduct regular security assessments and penetration tests focusing on SSRF and related vulnerabilities in web applications and CMS platforms. 7) If possible, deploy Web Application Firewalls (WAFs) with rules designed to detect and block SSRF attack patterns targeting the 'cjurl' parameter. These measures, combined, will reduce the likelihood and impact of exploitation beyond generic advice.
