CVE-2025-11371 is a Local File Inclusion (LFI) vulnerability found in Gladinet CentreStack and TrioFox, two file sharing and collaboration platforms widely used in enterprise environments. The vulnerability exists in the default installation and configuration of these products, allowing an unauthenticated attacker to include and read arbitrary system files on the server hosting the application. This flaw arises due to improper input validation and insufficient access controls on file inclusion mechanisms, categorized under CWE-552 (Files or Directories Accessible to External Parties). Exploiting this vulnerability does not require any authentication or user interaction, and it can be triggered remotely over the network, making it highly accessible to attackers. The impact is primarily on confidentiality, as attackers can access sensitive files that may contain credentials, configuration details, or other critical information. The versions affected include all releases up to and including 16.7.10368.56560. Although no public exploits have been confirmed in the wild, the vulnerability's CVSS score of 7.5 (high) reflects the significant risk posed by this flaw. The lack of available patches at the time of reporting highlights the urgency for organizations to implement interim mitigations. This vulnerability underscores the importance of secure default configurations and rigorous input validation in web-facing applications.

For European organizations, the exploitation of CVE-2025-11371 could lead to unauthorized disclosure of sensitive system files, potentially exposing confidential business data, user credentials, or internal configuration files. This can facilitate further attacks such as privilege escalation, lateral movement, or data exfiltration. Organizations relying on Gladinet CentreStack and TrioFox for secure file sharing and collaboration may face operational disruptions and reputational damage if sensitive information is leaked. The breach of confidentiality could also lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. Critical sectors such as finance, healthcare, and government agencies are particularly vulnerable due to the sensitive nature of their data and the reliance on secure file sharing solutions. The ease of exploitation without authentication increases the threat surface, making it imperative for organizations to act swiftly. Additionally, attackers could leverage disclosed information to craft more sophisticated attacks targeting European infrastructure and enterprises.

1. Monitor Gladinet's official channels for security advisories and apply patches immediately once they are released to address CVE-2025-11371. 2. Until patches are available, restrict network access to CentreStack and TrioFox services using firewalls or VPNs, limiting exposure to trusted internal networks only. 3. Implement web application firewalls (WAFs) with rules designed to detect and block attempts at Local File Inclusion attacks targeting these products. 4. Conduct thorough audits of server file permissions and configurations to minimize the risk of sensitive file exposure. 5. Enable detailed logging and monitor for unusual file access patterns or requests that could indicate exploitation attempts. 6. Educate IT and security teams about this vulnerability to ensure rapid detection and response. 7. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect LFI attack signatures. 8. Review and harden default configurations of CentreStack and TrioFox installations, disabling any unnecessary features or services that could increase attack surface. 9. If feasible, isolate affected systems in segmented network zones to contain potential breaches. 10. Prepare incident response plans specific to file inclusion attacks to reduce response time in case of exploitation.
