CVE-2025-47728: CWE-787 Out-of-bounds Write in Delta Electronics CNCSoft-G2
Delta Electronics CNCSoft-G2 lacks proper validation of the user-supplied file. If a user opens a malicious file, an attacker can leverage this vulnerability to execute code in the context of the current process.
AI Analysis
Technical Summary
CVE-2025-47728 is a high-severity vulnerability identified in Delta Electronics' CNCSoft-G2 software, a product used for controlling CNC (Computer Numerical Control) machinery. The vulnerability is classified as CWE-787, which corresponds to an out-of-bounds write error. Specifically, the software lacks proper validation of user-supplied files. When a user opens a maliciously crafted file, the vulnerability can be exploited to execute arbitrary code within the context of the current process. This means that an attacker who can trick a user into opening a malicious file can potentially run code with the same privileges as the user running CNCSoft-G2. The CVSS 4.0 score of 7.3 reflects a high severity, with the vector indicating that the attack requires local access (AV:L), low attack complexity (AC:L), privileges required are high (PR:H), user interaction is required (UI:A), and there are high impacts on confidentiality, integrity, and availability. The vulnerability affects version 0 of the product, which likely indicates the initial or a specific version of CNCSoft-G2. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved in early May 2025 and published in June 2025, indicating recent discovery and disclosure. The technical root cause is improper bounds checking when processing user-supplied files, leading to memory corruption that can be leveraged for code execution.
Potential Impact
For European organizations, particularly those in manufacturing sectors relying on CNC machinery controlled by Delta Electronics' CNCSoft-G2, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, potentially allowing attackers to disrupt manufacturing processes, cause physical damage to machinery, or steal sensitive operational data. Given the high privileges required and the need for user interaction, the threat is more likely to arise from targeted attacks or insider threats rather than remote mass exploitation. However, the impact on operational technology (OT) environments can be severe, including downtime, loss of production, and safety hazards. Confidentiality breaches could expose proprietary manufacturing designs or processes, while integrity violations could lead to manipulated machine instructions, resulting in defective products or equipment damage. Availability impacts could halt production lines, causing financial losses and supply chain disruptions. The lack of patches at the time of disclosure increases the urgency for mitigation in European industrial environments.
Mitigation Recommendations
European organizations using CNCSoft-G2 should immediately implement strict file handling policies to prevent opening untrusted or unsolicited files within the software. Employ network segmentation to isolate CNC control systems from general IT networks, reducing the risk of malicious file delivery. Enforce the principle of least privilege by ensuring that users running CNCSoft-G2 have minimal necessary permissions, limiting the potential damage from code execution. Monitor and audit user activities related to file operations in CNCSoft-G2 to detect suspicious behavior. Until an official patch is released, consider deploying application whitelisting or sandboxing techniques to restrict the execution context of CNCSoft-G2. Additionally, educate users about the risks of opening files from unverified sources and implement multi-factor authentication to reduce the risk of compromised credentials being used to exploit the vulnerability. Regularly check for vendor updates and apply patches promptly once available.
