CVE-2025-14008 is a server-side request forgery vulnerability identified in dayrui XunRuiCMS versions up to 4.7.1, specifically within the file admin79f2ec220c7e.php in the 'Project Domain Change Test' component. The vulnerability stems from improper sanitization or validation of the 'v' parameter, which is used in a server-side request operation. An attacker can remotely manipulate this parameter to coerce the server into making arbitrary HTTP requests to internal or external systems. This SSRF flaw can be exploited without user interaction but requires the attacker to have some level of privilege (PR:H), indicating that some form of authentication or elevated access is necessary. The CVSS 4.0 score is 5.1 (medium severity), reflecting moderate impact on confidentiality, integrity, and availability, with low complexity and no user interaction needed. The vendor was contacted but did not respond, and no official patches or fixes have been released. Although no active exploitation in the wild has been reported, published exploit code increases the risk of future attacks. SSRF vulnerabilities can be leveraged to bypass firewalls, access internal services, or perform further attacks such as data exfiltration or lateral movement within a network. Given the CMS’s role in managing web content, exploitation could also lead to indirect impacts on website availability or integrity if combined with other vulnerabilities.

For European organizations, this SSRF vulnerability poses a risk primarily to internal network security and data confidentiality. If exploited, attackers could use the vulnerable CMS server as a pivot point to scan internal networks, access sensitive internal services (such as databases, internal APIs, or cloud metadata endpoints), or exfiltrate data. This could lead to unauthorized disclosure of sensitive information or facilitate further attacks within the corporate network. Organizations relying on XunRuiCMS for critical web infrastructure or customer-facing portals may face service disruptions or reputational damage if attackers chain this SSRF with other vulnerabilities. The lack of vendor response and absence of patches increase the window of exposure. Additionally, the requirement for some privilege means insider threats or compromised accounts could be leveraged to exploit this flaw. European entities with strict data protection regulations (e.g., GDPR) must consider the compliance implications of potential data breaches stemming from this vulnerability.

1. Restrict access to the vulnerable API endpoint (admin79f2ec220c7e.php?c=api&m=test_site_domain) by implementing network-level controls such as IP whitelisting or VPN-only access. 2. Employ strict input validation and sanitization on the 'v' parameter to ensure only expected, safe values are processed, ideally blocking any URLs or IP addresses that could lead to internal resources. 3. Monitor and log outbound HTTP requests from the CMS server to detect unusual or unauthorized connections indicative of SSRF exploitation attempts. 4. Implement web application firewalls (WAFs) with custom rules to detect and block SSRF patterns targeting this endpoint. 5. Limit privileges of CMS users to the minimum necessary to reduce the risk of exploitation by authenticated attackers. 6. If possible, isolate the CMS server in a segmented network zone with restricted access to internal services. 7. Stay alert for vendor updates or community patches and apply them promptly once available. 8. Conduct regular security assessments and penetration tests focusing on SSRF and related vulnerabilities in the CMS environment.
