CVE-2025-53416: CWE-502 Deserialization of Untrusted Data in Delta Electronics DTN Soft
Delta Electronics DTN Soft Project File Parsing Deserialization of Untrusted Data Remote Code Execution
AI Analysis
Technical Summary
CVE-2025-53416 is a high-severity vulnerability identified in Delta Electronics' DTN Soft product, specifically related to the deserialization of untrusted data during the parsing of project files. The vulnerability is classified under CWE-502, which involves unsafe deserialization that can lead to remote code execution (RCE). In this case, an attacker could craft malicious project files that, when processed by DTN Soft, trigger the deserialization of malicious payloads. This can allow the attacker to execute arbitrary code on the affected system. The CVSS 3.1 base score is 7.8, indicating a high severity level. The vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reveals that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Despite the severity, no known exploits are reported in the wild, and no patches or mitigations have been published yet. The vulnerability was reserved and published on June 30, 2025, but the state is marked as REJECTED in the technical details, which may indicate some dispute or reconsideration of the vulnerability status by the vendor or CVE authority. However, the technical risk remains significant given the nature of the flaw and potential impact if exploited.
Potential Impact
For European organizations using Delta Electronics' DTN Soft, this vulnerability poses a significant risk. DTN Soft is typically used in industrial automation and control systems, sectors critical to manufacturing, energy, and infrastructure. Successful exploitation could lead to full system compromise, allowing attackers to execute arbitrary code, potentially disrupting operations, stealing sensitive intellectual property, or causing safety hazards. Given the local attack vector with required user interaction, insider threats or targeted phishing campaigns could be effective attack vectors. The high impact on confidentiality, integrity, and availability means that critical industrial processes could be halted or manipulated, leading to financial losses, regulatory penalties, and reputational damage. European organizations in manufacturing hubs, energy production, and critical infrastructure sectors are particularly at risk, especially those relying on Delta Electronics hardware and software solutions.
Mitigation Recommendations
Since no patches are currently available, European organizations should implement strict controls around the use and handling of DTN Soft project files. This includes: 1) Restricting access to DTN Soft installations to trusted personnel only, minimizing the risk of malicious file introduction. 2) Implementing strict file validation and scanning procedures for any project files before opening them in DTN Soft, using advanced malware detection tools capable of analyzing serialized data. 3) Employing application whitelisting and sandboxing techniques to limit the impact of potential code execution. 4) Enhancing user training to recognize and avoid social engineering attempts that could lead to opening malicious files. 5) Monitoring system and application logs for unusual activity related to DTN Soft usage. 6) Engaging with Delta Electronics for updates or patches and participating in vendor security advisories. 7) Considering network segmentation to isolate systems running DTN Soft from broader enterprise networks to contain potential breaches.
