Attack VectorLocal
Auth RequiredNone
ComplexityLow
User InteractionRequired
Summary
National Instruments LabVIEW versions 24.1f0 and earlier contain two memory safety vulnerabilities: an out-of-bounds read due to missing bounds checking (CWE-125) and memory corruption issues due to improper length checks (CWE-119). Both vulnerabilities are local in nature and require user interaction, such as opening a malicious LabVIEW project file. Successful exploitation allows a local attacker to disclose sensitive information from process memory and execute arbitrary code with the privileges of the LabVIEW application.
What this means
What could happen
A local attacker with access to a LabVIEW system could read sensitive memory and execute arbitrary code on the engineering workstation, potentially modifying control logic or stealing credentials used to access field devices.
Who's at risk
Engineering teams and control system operators at water utilities, power plants, and manufacturing facilities who use National Instruments LabVIEW for SCADA programming, PLC/RTU development, and process control system design are affected. Risk is highest for organizations where LabVIEW workstations have access to credentials or network connectivity to field devices.
How it could be exploited
An attacker with local access to a LabVIEW engineering workstation could trigger an out-of-bounds read or memory corruption condition through a crafted file or user interaction, allowing them to read process memory (disclosing engineering logic or credentials) or execute arbitrary code with the privileges of the LabVIEW process.
Prerequisites
- Local access to the LabVIEW system
- User interaction required (likely opening a malicious file or project)
- LabVIEW version 24.1f0 or earlier
Local exploitation only (requires workstation access)User interaction requiredHigh severity (CVSS 7.8)Affects engineering/development systems with control logic accessOut-of-bounds read and memory corruptionNo public exploitation reported
Exploitability
Low exploit probability (EPSS 0.2%)
