CVE-2025-10397 is a server-side request forgery (SSRF) vulnerability identified in Magicblack MacCMS version 2025.1000.4050, specifically within an unspecified part of the API Handler component. The vulnerability arises from improper validation or sanitization of the 'cjurl' argument, which an attacker can manipulate to coerce the server into making unauthorized HTTP requests. This flaw allows a remote attacker to induce the vulnerable server to send crafted requests to internal or external systems, potentially bypassing network access controls. The vulnerability does not require user interaction and can be exploited remotely without authentication, although the CVSS vector indicates a requirement for high privileges (PR:H), suggesting that exploitation might require some level of authenticated access or elevated permissions on the system. The CVSS 4.0 base score is 5.1 (medium severity), reflecting limited confidentiality, integrity, and availability impacts, with low vector and impact complexity. The vulnerability's exploitation could lead to information disclosure, internal network reconnaissance, or interaction with internal services not normally accessible externally. No patches or fixes have been published yet, and while public exploits exist, there are no known active exploitations in the wild at this time. The vulnerability's presence in a content management system (CMS) used for media management implies that affected organizations could face risks related to unauthorized internal network scanning or indirect attacks on internal infrastructure through SSRF techniques.

For European organizations using Magicblack MacCMS 2025.1000.4050, this SSRF vulnerability poses a moderate risk. Exploitation could allow attackers to pivot from the compromised CMS server into internal networks, potentially accessing sensitive internal services, databases, or administrative interfaces that are otherwise protected by network segmentation. This could lead to unauthorized data access, internal reconnaissance, or further exploitation chains. Given the CMS's role in managing media content, organizations in media, entertainment, and digital publishing sectors are particularly at risk. Additionally, SSRF can be leveraged to bypass firewalls or access cloud metadata services, which could lead to credential theft or privilege escalation in cloud environments. The medium severity rating suggests that while the vulnerability is not immediately critical, it could serve as a foothold for more severe attacks if combined with other vulnerabilities or misconfigurations. European organizations with strict data protection regulations (e.g., GDPR) must be cautious, as exploitation leading to data breaches could result in regulatory penalties and reputational damage.

To mitigate this SSRF vulnerability effectively, European organizations should: 1) Immediately audit and restrict access to the affected MacCMS API Handler, especially the 'cjurl' parameter, applying strict input validation and sanitization to ensure only allowed URLs or domains can be requested. 2) Implement network-level controls such as egress filtering and firewall rules to prevent the CMS server from making unauthorized outbound requests to internal or sensitive network segments. 3) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious SSRF payloads targeting the 'cjurl' parameter. 4) Monitor logs for unusual outbound HTTP requests originating from the CMS server, focusing on internal IP ranges or unexpected external destinations. 5) Segregate the CMS infrastructure from critical internal systems using network segmentation and zero-trust principles to limit lateral movement in case of compromise. 6) Engage with Magicblack for patches or updates and apply them promptly once available. 7) Conduct regular security assessments and penetration tests focusing on SSRF and API security to identify and remediate similar issues proactively.
