CVE-2025-39384 is a vulnerability classified under CWE-98, which involves improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the 'Product Lister for eBay' plugin developed by cedcommerce, up to version 2.0.9. The flaw allows for PHP Local File Inclusion (LFI), meaning an attacker can manipulate the filename parameter to include unintended local files on the server. This can lead to the execution of arbitrary PHP code if the attacker can control the contents of the included files or access sensitive files on the server. The vulnerability arises because the application does not properly validate or sanitize the input used in include/require statements, allowing an attacker to traverse directories or specify files that should not be accessible. Although the description mentions 'PHP Remote File Inclusion,' the actual impact is local file inclusion, which is generally less severe than remote file inclusion but still critical in many contexts. No known exploits are currently reported in the wild, and no patches have been released at the time of this analysis. The vulnerability was published on April 24, 2025, and has been enriched by CISA, indicating recognition by cybersecurity authorities. The affected product is a plugin used to list products on eBay, likely integrated into e-commerce platforms that rely on PHP, such as WordPress or Magento. This vulnerability could be exploited by an attacker with network access to the web application, potentially without authentication depending on the plugin's configuration and exposure. Exploitation could allow attackers to read sensitive configuration files, execute arbitrary code, or escalate privileges within the web server context.

For European organizations, this vulnerability poses a significant risk, especially for e-commerce businesses using the cedcommerce Product Lister for eBay plugin. Successful exploitation could lead to unauthorized disclosure of sensitive data such as database credentials, customer information, or internal configuration files, impacting confidentiality. Additionally, attackers could execute arbitrary code on the web server, compromising integrity and availability by defacing websites, injecting malicious scripts, or causing denial of service. Given the plugin's role in managing product listings, disruption could directly affect business operations and revenue. The impact is heightened for organizations that handle large volumes of customer data or financial transactions, as data breaches could trigger regulatory penalties under GDPR. Moreover, the vulnerability could be leveraged as a foothold for lateral movement within the network, increasing the risk of broader compromise. Since no patches are currently available, organizations remain exposed until mitigations are applied. The lack of known exploits in the wild suggests limited current targeting, but the public disclosure may attract attackers to develop exploits, increasing future risk.

1. Immediate mitigation should include restricting access to the affected plugin's functionality by limiting network exposure through web application firewalls (WAFs) or IP whitelisting to trusted users only. 2. Implement strict input validation and sanitization at the application level to prevent manipulation of include/require parameters, ensuring only expected filenames are processed. 3. Disable PHP functions that facilitate file inclusion or execution if not required, such as 'include', 'require', 'include_once', and 'require_once', or use PHP configuration directives like 'open_basedir' to restrict file system access to necessary directories. 4. Monitor web server logs for suspicious requests containing directory traversal patterns or unusual file inclusion attempts. 5. Employ runtime application self-protection (RASP) tools that can detect and block file inclusion attacks in real-time. 6. Engage with cedcommerce for updates and patches, and plan for prompt application of any security updates once released. 7. Conduct a thorough security review of all third-party plugins and dependencies to identify similar vulnerabilities. 8. For critical environments, consider isolating the plugin's execution context or deploying it in a sandboxed environment to limit potential damage.
