CVE-2025-57774 is a high-severity vulnerability identified in Digilent's DASYLab software, a data acquisition and control application widely used in engineering and scientific environments. The vulnerability stems from improper validation of specified index, position, or offset in input data, specifically when parsing DSB files, which are project files used by DASYLab. This improper bounds checking leads to an out-of-bounds write condition, allowing an attacker to overwrite memory locations beyond the intended buffer. Such memory corruption can result in arbitrary code execution within the context of the user running the application. Exploitation requires a user to open a specially crafted malicious DSB file, which triggers the vulnerability during file parsing. The CVSS 3.1 base score of 7.8 reflects the high impact on confidentiality, integrity, and availability, with an attack vector requiring local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction (UI:R) to open the malicious file. The vulnerability affects all versions of DASYLab, indicating a long-standing issue without a currently available patch. No known exploits have been reported 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 control tasks.

For European organizations, the impact of this vulnerability is significant, especially for those in industrial, research, and educational sectors where DASYLab is commonly used for data acquisition, instrumentation control, and experimental automation. Successful exploitation could lead to unauthorized code execution, enabling attackers to compromise sensitive data, disrupt critical measurement and control processes, or pivot to other networked systems. This could result in operational downtime, loss of data integrity, and potential safety risks in environments where DASYLab controls physical processes. Confidentiality breaches could expose proprietary research or intellectual property. The requirement for user interaction limits remote exploitation but does not eliminate risk, as targeted phishing or social engineering campaigns could deliver malicious DSB files. The lack of a patch increases exposure time, necessitating immediate mitigations to protect European organizations from potential attacks.

Given the absence of an official patch, European organizations should implement several specific mitigations: 1) Enforce strict file handling policies by restricting DSB file opening to trusted sources only and educating users about the risks of opening unsolicited or unexpected project files. 2) Employ application whitelisting and sandboxing techniques to limit the privileges and system access of DASYLab processes, reducing the impact of potential code execution. 3) Utilize endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unexpected memory writes or process injections. 4) Implement network segmentation to isolate systems running DASYLab from critical infrastructure and sensitive data repositories. 5) Regularly back up critical data and configuration files to enable recovery in case of compromise. 6) Engage with Digilent for updates and subscribe to vulnerability advisories to apply patches promptly once available. 7) Consider deploying file integrity monitoring on directories where DSB files are stored or accessed to detect unauthorized modifications.
