CVE-2025-9189 is a high-severity vulnerability identified in Digilent's DASYLab software, a data acquisition and control application widely used for engineering and scientific data analysis. The vulnerability is classified under CWE-1285, which pertains to improper validation of specified index, position, or offset in input. Specifically, this flaw arises from insufficient bounds checking when parsing DSB files, the proprietary file format used by DASYLab. An attacker can craft a malicious DSB file containing out-of-bounds data that causes an out-of-bounds write operation, leading to memory corruption. This memory corruption can be leveraged to execute arbitrary code on the victim's machine. Exploitation requires user interaction, as the victim must open the specially crafted DSB file within DASYLab. The CVSS 3.1 base score of 7.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required, but user interaction is necessary. All versions of DASYLab are affected, and no patches have been released at the time of publication. There are no known exploits in the wild yet, but the potential for arbitrary code execution makes this a critical concern for environments relying on DASYLab for data acquisition and analysis.

For European organizations, the impact of CVE-2025-9189 can be significant, especially those in sectors such as manufacturing, research institutions, universities, and engineering firms that utilize DASYLab for data acquisition and control. Successful exploitation could lead to unauthorized code execution, resulting in data theft, manipulation of experimental or operational data, disruption of critical processes, or deployment of further malware. Given that DASYLab often interfaces with hardware and instrumentation, exploitation could also cause physical process disruptions or safety hazards. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious DSB files, increasing the risk in environments with less stringent file handling policies. The absence of a patch increases exposure time, and organizations may face compliance and operational risks if the vulnerability is exploited.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately restrict the opening of DSB files from untrusted or unknown sources. 2) Educate users about the risks of opening unsolicited or suspicious DSB files, emphasizing cautious handling of email attachments and downloads. 3) Employ application whitelisting and sandboxing techniques to isolate DASYLab processes, limiting the impact of potential exploitation. 4) Monitor network and endpoint activity for anomalous behavior indicative of exploitation attempts, such as unexpected process launches or memory access violations. 5) Coordinate with Digilent for timely updates and apply patches as soon as they become available. 6) Consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation patterns related to out-of-bounds writes and arbitrary code execution. 7) Implement strict access controls and segmentation for systems running DASYLab to minimize lateral movement if compromise occurs.
