CVE-2025-45474 is a high-severity Server-Side Request Forgery (SSRF) vulnerability identified in maccms10 version 2025.1000.4047, specifically within its Email Settings functionality. SSRF vulnerabilities occur when an attacker can manipulate a server to make unintended requests to internal or external systems, potentially bypassing network access controls. In this case, the vulnerability allows unauthenticated attackers to craft malicious requests that the vulnerable server processes, potentially leading to unauthorized information disclosure, integrity compromise, or availability disruption. The CVSS v3.1 base score is 7.3, reflecting a network attack vector with low attack complexity, no privileges required, and no user interaction needed. The impact includes partial confidentiality loss, integrity alteration, and availability degradation. The vulnerability is categorized under CWE-918, which pertains to SSRF issues. Although no patch links or known exploits in the wild are currently reported, the presence of this vulnerability in a content management system (CMS) component related to email settings suggests that attackers might leverage it to access internal services, perform port scanning, or exploit further internal vulnerabilities. The lack of vendor or product details limits precise identification, but the versioning implies a CMS or web application platform context. The SSRF in Email Settings might allow attackers to manipulate email server configurations or trigger requests that could expose sensitive internal endpoints or metadata services if the server is hosted in cloud environments.

For European organizations using maccms10 or similar CMS platforms, this SSRF vulnerability poses significant risks. Exploitation could lead to unauthorized access to internal network resources, including intranet services, databases, or cloud metadata endpoints, potentially resulting in data leakage or lateral movement within corporate networks. Confidentiality breaches could expose sensitive customer or business data, while integrity impacts might allow attackers to alter email configurations or other critical settings, disrupting communications. Availability could also be affected if attackers leverage the SSRF to trigger denial-of-service conditions on internal services. Given the increasing reliance on cloud infrastructure and the integration of CMS platforms in business operations across Europe, this vulnerability could facilitate espionage, data theft, or sabotage, especially in sectors like finance, healthcare, and government. The absence of known exploits currently provides a window for proactive mitigation, but the vulnerability's ease of exploitation and network accessibility make it a pressing concern.

European organizations should immediately audit their use of maccms10 version 2025.1000.4047 or related CMS products to identify affected instances. Since no official patches are currently available, organizations should implement strict network segmentation to isolate the CMS servers from sensitive internal resources and restrict outbound HTTP requests from these servers to only trusted endpoints. Employing Web Application Firewalls (WAFs) with custom rules to detect and block SSRF patterns targeting email settings can reduce risk. Additionally, input validation and sanitization should be enforced on all parameters related to email configuration to prevent malicious request injection. Monitoring and logging outbound requests from the CMS server will help detect anomalous activity indicative of SSRF exploitation attempts. Organizations should also prepare incident response plans specific to SSRF attacks and stay alert for vendor updates or patches addressing this vulnerability. Finally, consider deploying runtime application self-protection (RASP) solutions that can detect and block SSRF attempts in real time.
