CVE-2025-53415 is a high-severity vulnerability classified under CWE-502, which pertains to the deserialization of untrusted data. This vulnerability affects Delta Electronics' DTM Soft product, specifically during the parsing of project files. The flaw allows an attacker to craft malicious project files that, when parsed by the vulnerable version of DTM Soft, trigger unsafe deserialization processes. This can lead to remote code execution (RCE) on the affected system. The vulnerability has a CVSS v3.1 base score of 7.8, indicating a high level of severity. The vector string 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), has low attack complexity (AC:L), does not require privileges (PR:N), but does require user interaction (UI:R). The scope remains unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability arises because the software improperly handles deserialization of project files, which can be manipulated to execute arbitrary code, potentially compromising the host system. This type of vulnerability is critical in industrial control and automation environments where DTM Soft is used for device configuration and management.

For European organizations, especially those in industrial automation, manufacturing, and critical infrastructure sectors that utilize Delta Electronics' DTM Soft, this vulnerability poses a significant risk. Successful exploitation could lead to full system compromise, allowing attackers to execute arbitrary code, potentially disrupting industrial processes, causing data breaches, or leading to operational downtime. Given the local attack vector but requirement for user interaction, insider threats or targeted attacks involving social engineering could be effective. The high impact on confidentiality, integrity, and availability means sensitive operational data could be exposed or manipulated, and control systems could be sabotaged. This could have cascading effects on supply chains and critical services, particularly in countries with a strong industrial base or reliance on automated manufacturing systems.

Organizations should immediately audit their use of Delta Electronics DTM Soft and restrict access to trusted users only. Since no patches are currently available, mitigation should focus on minimizing exposure: 1) Implement strict file handling policies to prevent opening project files from untrusted or unknown sources. 2) Employ application whitelisting and endpoint protection solutions to detect and block suspicious behaviors related to deserialization or code execution. 3) Educate users on the risks of opening unsolicited project files and enforce strong user awareness training to reduce the risk of social engineering. 4) Use network segmentation to isolate systems running DTM Soft from broader enterprise networks to limit lateral movement in case of compromise. 5) Monitor logs and system behavior for anomalies indicative of exploitation attempts. Once a patch is released by Delta Electronics, prioritize its deployment. Additionally, consider virtualizing or sandboxing the application environment to contain potential exploits.
