CVE-2025-57777 is a high-severity vulnerability identified in Digilent's DASYLab software, specifically involving an out-of-bounds write in the displ2.dll component when parsing DSB files. The root cause is improper validation of specified index, position, or offset in input data, classified under CWE-1285. This flaw allows an attacker to craft a malicious DSB file that, when opened by a user, triggers an out-of-bounds write condition. Such memory corruption can lead to arbitrary code execution, potentially allowing the attacker to execute code with the privileges of the user running DASYLab. Exploitation requires user interaction—specifically, opening the malicious file—and no prior authentication or elevated privileges are necessary. The vulnerability affects all versions of DASYLab, indicating a systemic issue in the file parsing logic. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and no privileges required. No patches have been released yet, and there are no known exploits in the wild as of the publication date. Given that DASYLab is used for data acquisition and analysis in engineering and scientific environments, this vulnerability could be leveraged to compromise sensitive data or disrupt critical measurement and control processes.

For European organizations, the impact of this vulnerability can be significant, especially in sectors relying on DASYLab for data acquisition, automation, and analysis such as manufacturing, research institutions, energy, and industrial control systems. Successful exploitation could lead to unauthorized access, data manipulation, or disruption of operational technology environments. This could result in intellectual property theft, operational downtime, safety hazards, and regulatory non-compliance, particularly under GDPR and NIS Directive frameworks. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious DSB files, increasing the risk surface. Organizations with distributed engineering teams or those sharing DSB files across networks are particularly vulnerable. The lack of patches necessitates immediate risk mitigation to prevent potential exploitation as threat actors may develop exploits over time.

1. Implement strict file handling policies: Restrict the opening of DSB files to trusted sources only and educate users on the risks of opening unsolicited or unexpected files. 2. Employ network-level controls: Use email and web filtering to block or quarantine suspicious DSB files and attachments. 3. Utilize application whitelisting and sandboxing: Run DASYLab in a controlled environment to limit the impact of potential exploitation. 4. Monitor and audit usage: Track DASYLab file openings and monitor for anomalous behavior indicative of exploitation attempts. 5. Maintain up-to-date backups: Ensure critical data and configurations are backed up regularly to enable recovery in case of compromise. 6. Engage with Digilent for updates: Monitor vendor communications for patches or mitigations and apply them promptly once available. 7. Consider compensating controls: If feasible, isolate systems running DASYLab from internet access or untrusted networks to reduce exposure. 8. Conduct user awareness training focused on spear-phishing and social engineering tactics relevant to this vulnerability.
