CVE Alert: CVE-2025-11318 – Tipray 厦门天锐科技股份有限公司 – Data Leakage Prevention System 天锐数据泄露防护系统

Risk verdict

High risk: publicly released exploit for unrestricted file upload on Tipray Data Leakage Prevention System; urgent remediation advised.

Why this matters

Unrestricted upload can enable an attacker to place arbitrary files on the appliance, potentially leading to remote code execution or data exposure. Despite a medium overall CVSS 4.0 base, the combination of network access, no authentication, and a publicly disclosed exploit elevates practical risk for exposed deployments.

Most likely attack path

An adversary can reach the upload endpoint over the network without credentials or user interaction. The low attack complexity and lack of required UI interaction permit automated probing. If the uploaded content is stored or executed, there is potential for further access or lateral movement within the affected host, though the reported impacts are currently limited to the device’s own scope.

Who is most exposed

Enterprise environments running on-prem or cloud-hosted DLP appliances with web-facing upload functionality are at highest risk, especially where the management interface is reachable from the wider network or DMZ.

Detection ideas

• Look for anomalous or high-volume uploads to uploadWxFile.do from external IPs.
• Identify atypical file types or payloads uploaded without corresponding user actions.
• Correlate web server logs with sudden surges in upload requests and any failed authentication attempts.
• Monitor for new or modified files in the appliance’s storage paths linked to upload handlers.
• Alert on evidence of automated scanners targeting file upload endpoints.

Mitigation and prioritisation

• Apply vendor patch to correct unrestricted upload flaw; verify deployment in staging before production.
• Disable or tightly restrict the uploadWxFile.do functionality if a workaround exists; enforce strict file type validation and size limits.
• Enforce authentication, MFA, and least-privilege access for DLP interfaces; deploy network segmentation and robust WAF rules.
• Enable detailed logging and real-time alerting for upload endpoints; perform rapid incident review if suspicious activity is detected.
• Plan a rapid rollback or hotfix path; revalidate after remediation.
