Deeper analysis
CVE-2025-53416 is a deserialization of untrusted data vulnerability (CWE-502) in Delta Electronics DTN Soft that enables remote code execution during project file parsing. The affected component processes untrusted project files, and the flaw carries a CVSS 3.1 score of 7.8 reflecting local attack vector, low complexity, no privileges required, and required user interaction.
An attacker can exploit the issue by supplying a malicious project file that the victim opens in DTN Soft. Successful exploitation grants the attacker arbitrary code execution on the target system with full impact to confidentiality, integrity, and availability.
The vendor has published an advisory at https://www.deltaww.com/en-US/Cybersecurity_Advisory that addresses the issue. The associated EPSS score has remained flat at 0.0199 with no material increase since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
