Horizon Alert
Summary of the vulnerability and why it matters
This critical vulnerability in Dongsheng Logistics Software allows attackers to upload and execute malicious files, potentially giving them full control over the server. Because it doesn't require authentication and can be reached from the internet, it's a significant risk for organizations using this software.
- Remote code execution is possible.
- Leads to server compromise.
- Unauthenticated access is sufficient.
Attack Path
How an attacker could exploit the issue
An attacker can abuse this flaw by uploading a web shell via an unauthenticated endpoint. This allows for remote code execution on the server, granting the attacker control.
- No authentication required.
- Target: `/CommMng/Print/UploadMailFile`.
- Upload executable scripts.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability allows unauthenticated remote code execution through arbitrary file uploads to an unpatched Dongsheng Logistics Software endpoint, presenting a significant risk to affected systems. The exploitation was first observed in late July 2025, and while the vendor has released a fix, widespread patching is likely incomplete given the deferred status and undefined affected version range. Attackers are likely to target this vulnerability due to its ease of exploitation and high impact, especially in organizations relying on this specific logistics software.
- Exploitation observed in July 2025.
- Remote code execution is possible.
- Affects unpatched builds.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize identifying and blocking inbound traffic to the unauthenticated `/CommMng/Print/UploadMailFile` endpoint, as it allows remote code execution and exploitation has been observed. Given the critical severity and active exploitation, immediately investigate all deployed Dongsheng Logistics Software instances to determine if they are affected and consider taking them offline or isolating them until a patch or reliable mitigation can be applied.
- Block access to the vulnerable endpoint.
- Inventory all Dongsheng Logistics Software instances.
- Upgrade to a patched version when available.
