Overview
CVE-2025-14004 details a server-side request forgery (SSRF) vulnerability found in dayrui XunRuiCMS up to version 4.7.1. This flaw resides within the Email Setting Handler, specifically affecting an unknown function of the file /admind45f74adbd95.php?c=email&m=add. An attacker can exploit this vulnerability to perform unauthorized network requests from the server, potentially leading to information disclosure or internal network exploitation.
Technical Details
The vulnerability allows a remote attacker to manipulate the input parameters of the /admind45f74adbd95.php?c=email&m=add script to force the server to make requests to arbitrary URLs. This is a classic SSRF scenario. Because the vendor did not respond to responsible disclosure attempts, details on the exact vulnerable parameter are publicly available. The public exploit demonstrates the ability to specify an arbitrary URL that the server will then attempt to access. This could be used to scan internal networks, access internal services, or potentially exfiltrate sensitive information.
CVSS Analysis
The CVSS score for CVE-2025-14004 is 4.7 (MEDIUM). This score reflects the potential for remote exploitation without requiring authentication. The impact is primarily on confidentiality and integrity, as an attacker can potentially access sensitive internal resources and possibly modify data through internal APIs.
Possible Impact
Successful exploitation of this SSRF vulnerability can have several serious consequences:
- Internal Network Scanning: An attacker can use the vulnerable server to scan the internal network for open ports and services, gathering valuable information for further attacks.
- Access to Internal Services: The attacker can access internal services that are not directly accessible from the internet, such as databases, APIs, or administrative panels.
- Information Disclosure: Sensitive information stored on internal servers or accessible through internal APIs can be exposed.
- Denial of Service (DoS): In some cases, an attacker might be able to overload internal services, leading to a denial of service.
Mitigation or Patch Steps
Unfortunately, as of this writing, the vendor has not released a patch for this vulnerability and has not responded to disclosure attempts. Therefore, the following mitigation steps are recommended:
- Restrict Network Access: Implement strict firewall rules to limit the server’s ability to make outbound connections to only necessary destinations. Specifically, block access to internal network ranges if possible.
- Input Validation and Sanitization: Carefully validate and sanitize all user-supplied input to the
/admind45f74adbd95.php?c=email&m=addscript. Implement a whitelist of allowed protocols and domains for any URL parameters. This is *crucial* even without a patch. - Web Application Firewall (WAF): Deploy a web application firewall (WAF) to detect and block malicious requests targeting this vulnerability. Configure the WAF to identify and block attempts to manipulate URL parameters for SSRF.
- Monitor Outbound Traffic: Monitor outbound network traffic for unusual activity, such as connections to unexpected IP addresses or ports.
- Disable the feature: If possible and if the email setting functionality is not business critical, disable the functionality completely.
Important: Given the vendor’s lack of response, consider migrating to a different CMS platform if a timely patch is not released. The ongoing risk is significant.
