CVE-2025-14004 is a server-side request forgery vulnerability affecting dayrui XunRuiCMS versions 4.7.0 and 4.7.1. The vulnerability resides in an unspecified function within the Email Setting Handler component, accessible via the endpoint /admind45f74adbd95.php?c=email&m=add. An attacker with high-level privileges can manipulate this function to cause the server to make unauthorized requests to internal or external resources. SSRF vulnerabilities can be leveraged to bypass network access controls, access sensitive internal services, or perform reconnaissance within the victim's network. The vulnerability does not require user interaction but does require the attacker to have authenticated access with high privileges, which limits exploitation to insiders or compromised accounts. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no authentication required (PR:H means privileges required but no additional authentication), no user interaction, and low impact on confidentiality, integrity, and availability. Despite the medium severity score (5.1), the public release of an exploit increases the urgency of addressing this issue. The vendor has not provided a patch or response, leaving organizations to rely on mitigations. The lack of patches and public exploit availability make this a significant risk for affected installations. The vulnerability's presence in a CMS component related to email settings suggests potential for abuse in internal network scanning or accessing restricted services, which could lead to further compromise or data leakage.

For European organizations using dayrui XunRuiCMS versions 4.7.0 or 4.7.1, this SSRF vulnerability poses a risk of unauthorized internal network access and potential lateral movement. Attackers with high privileges could exploit this flaw to access internal services that are otherwise inaccessible from the internet, potentially exposing sensitive data or enabling further attacks such as privilege escalation or data exfiltration. Given the CMS's role in managing website content and email settings, exploitation could disrupt business operations or compromise communication channels. Organizations in sectors with strict data protection regulations (e.g., finance, healthcare, government) face increased risk of regulatory non-compliance and reputational damage if internal systems are breached. The public availability of an exploit increases the likelihood of opportunistic attacks, especially in environments where user privileges are not tightly controlled. The absence of vendor patches means organizations must rely on compensating controls, increasing operational overhead and risk. Overall, the vulnerability could lead to moderate to significant operational and security impacts depending on the internal network architecture and privilege management.

1. Immediately restrict access to the vulnerable endpoint (/admind45f74adbd95.php?c=email&m=add) by implementing network-level controls such as IP whitelisting or firewall rules limiting access to trusted administrators only. 2. Enforce strict privilege management to ensure only necessary users have high-level access to the CMS backend, reducing the attack surface. 3. Monitor server logs and network traffic for unusual outbound requests originating from the CMS server, which may indicate exploitation attempts. 4. Implement internal network segmentation to limit the ability of compromised services to access sensitive internal resources. 5. Use web application firewalls (WAF) with custom rules to detect and block SSRF attack patterns targeting the vulnerable endpoint. 6. Regularly audit and update CMS user accounts and permissions to prevent unauthorized privilege escalation. 7. Consider deploying temporary reverse proxies or API gateways that can sanitize or validate requests to the vulnerable component. 8. Stay alert for vendor updates or community patches and plan for prompt application once available. 9. Conduct internal penetration testing focusing on SSRF and privilege abuse scenarios to identify and remediate related weaknesses. 10. Educate administrators on the risks of SSRF and the importance of secure configuration and monitoring.
