Overview
The cybersecurity community has recently identified a new vulnerability, termed CVE-2025-30419, that affects the NI Circuit Design Suite. This vulnerability is particularly concerning due to its memory corruption capabilities, which may result in information disclosure or arbitrary code execution. Specifically, the vulnerability is associated with an out of bounds read in GetSymbolBorderRectSize() when using the SymbolEditor. It affects versions 14.3.0 and prior of the NI Circuit Design Suite, a software widely used for the design of complex electronic circuits.
Given the extensive usage of this software suite in the electronics industry, this vulnerability carries significant potential for system compromise or data leakage. Successful exploitation requires user interaction, specifically the opening of a maliciously crafted .sym file.

How the Exploit Works
The exploit takes advantage of a memory corruption vulnerability due to an out of bounds read in the GetSymbolBorderRectSize() function when using the SymbolEditor in the NI Circuit Design Suite. An attacker crafts a .sym file containing malicious code, which when opened by a user, triggers the vulnerability. The memory corruption then allows for arbitrary code execution or information disclosure, leading to potential system compromise or data leakage.
Conceptual Example Code
For illustrative purposes, the below pseudocode demonstrates a general idea of how an attacker may craft a malicious .sym file that exploits the vulnerability:
create sym_file
function craft_malicious_code() {
// Code that triggers the memory corruption in GetSymbolBorderRectSize()
// and executes arbitrary malicious actions
}
write craft_malicious_code() to sym_file
save sym_fileThe saved .sym file is then sent to the victim. Upon opening the file in the vulnerable application, the vulnerability is triggered, leading to potential system compromise or data leakage.
It is imperative for users to apply the vendor-supplied patch for this vulnerability or to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure.
