CVE-2025-53415
📋 TL;DR
This vulnerability allows remote code execution through deserialization of untrusted data in Delta Electronics DTM Soft project files. Attackers can craft malicious BIN files that, when parsed by the software, execute arbitrary code on the target system. This affects organizations using Delta Electronics DTM Soft and DTN Soft software for industrial automation.
💻 Affected Systems
- Delta Electronics DTM Soft
- Delta Electronics DTN Soft
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the industrial control system, potentially leading to physical damage, production disruption, or safety incidents.
Likely Case
Remote code execution allowing data theft, lateral movement within industrial networks, or installation of persistent malware.
If Mitigated
Limited impact if systems are air-gapped, have strict file transfer controls, and use least privilege principles.
🎯 Exploit Status
Exploitation requires the victim to open a malicious BIN file. No authentication is needed beyond file access. The vulnerability is in the parsing logic itself.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Delta Electronics security advisory PCSA-2025-00009
Restart Required: Yes
Instructions:
1. Download the security update from Delta Electronics support portal. 2. Backup existing project files. 3. Install the update following vendor instructions. 4. Restart the system. 5. Verify the update was successful.
🔧 Temporary Workarounds
Restrict BIN file processing
allBlock or restrict processing of BIN files from untrusted sources
Application whitelisting
windowsImplement application control to prevent execution of unauthorized code
🧯 If You Can't Patch
- Implement strict controls on file transfers - only accept BIN files from trusted sources
- Run DTM/DTN Soft in isolated environments with network segmentation and minimal privileges
🔍 How to Verify
Check if Vulnerable:
Check DTM Soft/DTN Soft version against the patched version in Delta advisory PCSA-2025-00009Check Version:
Check version in DTM Soft/DTN Soft 'About' dialog or installation directory propertiesVerify Fix Applied:
Verify the software version matches or exceeds the patched version specified in the advisory📡 Detection & Monitoring
