CVE-2025-31030 identifies a Local File Inclusion vulnerability in the PHP-based Ray Enterprise Translation software developed by Jiro Sasamoto. The vulnerability arises from improper validation or control of filenames passed to PHP include or require statements, which are used to dynamically load code or content. An attacker exploiting this flaw can manipulate the filename parameter to include arbitrary local files from the server filesystem. This can lead to disclosure of sensitive files such as configuration files, source code, or credentials, and may also enable remote code execution if combined with other vulnerabilities or misconfigurations. The affected product versions are up to and including 1.7.0. The vulnerability was reserved in March 2025 and published in April 2025, with no public exploits reported yet. The absence of a CVSS score requires an independent severity assessment. The vulnerability is significant because it targets a common PHP weakness and affects enterprise translation software, which may be deployed in environments handling sensitive multilingual content and data. The lack of patch links suggests that fixes may not yet be publicly available, emphasizing the need for immediate mitigation.

The impact of CVE-2025-31030 is substantial for organizations using Ray Enterprise Translation software. Successful exploitation can lead to unauthorized disclosure of sensitive internal files, including credentials, configuration data, or intellectual property. This compromises confidentiality and potentially integrity if attackers modify included files or leverage the vulnerability for further attacks such as remote code execution. The availability impact is generally low unless attackers use the vulnerability to disrupt service. Organizations relying on this software for critical translation services or handling sensitive multilingual data could face operational disruptions, data breaches, and reputational damage. The vulnerability's exploitation does not require user interaction, increasing the risk of automated attacks. Given the software’s niche but critical role, sectors such as government, multinational corporations, and translation service providers are particularly vulnerable. The absence of known exploits currently limits immediate widespread impact but does not reduce the urgency for remediation.

To mitigate CVE-2025-31030, organizations should first verify if they are running affected versions (<= 1.7.0) of Ray Enterprise Translation and plan to upgrade to a patched version once available. In the absence of an official patch, implement strict input validation and sanitization on all parameters used in include or require statements to prevent arbitrary file inclusion. Employ PHP configuration hardening, such as disabling allow_url_include and restricting open_basedir to limit accessible filesystem paths. Use web application firewalls (WAFs) with rules designed to detect and block LFI attack patterns. Conduct thorough code audits to identify and refactor unsafe dynamic includes. Monitor logs for suspicious file access attempts and anomalous behavior. Isolate the application environment with least privilege principles to minimize potential damage. Finally, maintain regular backups and incident response plans tailored to web application attacks.
