CVE-2026-0957 in DASYLab
Summary
by MITRE • 03/13/2026
There is a memory corruption vulnerability due to an out-of-bounds write when loading a corrupted file in Digilent DASYLab. This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted file. This vulnerability affects all versions of Digilent DASYLab.

This memory corruption vulnerability in Digilent DASYLab represents a critical security flaw that stems from improper input validation during file processing operations. The vulnerability manifests as an out-of-bounds write condition when the software attempts to load malformed or corrupted files, creating a scenario where attacker-controlled data can overwrite adjacent memory regions. This type of vulnerability falls under the CWE-787 category of out-of-bounds write conditions, which are particularly dangerous because they can lead to unpredictable behavior and system compromise. The flaw exists in the file parsing mechanism of DASYLab, where the application fails to properly validate array indices or buffer boundaries when processing user-supplied input data.
The operational impact of this vulnerability extends beyond simple memory corruption, creating potential pathways for both information disclosure and arbitrary code execution. When an attacker successfully crafts a malicious file that triggers this out-of-bounds write, the memory corruption can be leveraged to either extract sensitive information from the application's memory space or to inject and execute malicious code within the context of the running application. This makes the vulnerability particularly attractive to threat actors seeking to gain unauthorized access to systems running affected versions of DASYLab. The attack vector requires social engineering to convince users to open the malicious file, which aligns with common phishing and spear-phishing tactics described in the MITRE ATT&CK framework under technique T1059 for command and scripting interpreter and T1566 for credential harvesting.
The widespread impact of this vulnerability affects all versions of Digilent DASYLab, indicating that no patched version exists to address the underlying memory corruption issue. This creates a significant challenge for organizations that rely on this software for data acquisition and analysis tasks, particularly in industrial and educational environments where such software is commonly deployed. The vulnerability's exploitation requires user interaction, which provides some defense in depth through user awareness training and email filtering systems, but does not eliminate the risk entirely since users can be deceived through sophisticated social engineering attacks. Organizations should consider implementing network segmentation to limit the potential spread of exploitation and should monitor for suspicious file execution patterns in their environments.
Mitigation strategies should focus on both immediate protective measures and long-term remediation approaches. Users should be educated about the risks of opening unknown or untrusted files, particularly in the context of engineering and scientific software environments where such files might be encountered during collaborative work or software updates. Software vendors should prioritize developing and distributing patches that address the buffer overflow condition through proper input validation and bounds checking mechanisms. Additionally, system administrators should consider implementing application whitelisting policies to restrict execution of unauthorized software versions and should monitor for unusual file access patterns that might indicate exploitation attempts. The vulnerability also highlights the importance of secure coding practices and regular security assessments of software used in critical applications, as this type of memory corruption vulnerability can often be prevented through proper defensive programming techniques and comprehensive testing procedures.
