Overview<\/strong><\/p>\n

A severe cybersecurity vulnerability has been identified in the NI Circuit Design Suite. The vulnerability, known as CVE-2025-6034, affects the SymbolEditor component due to an out-of-bounds read in the DefaultFontOptions() function. This vulnerability has significant implications for users of the software as it may lead to unauthorized information disclosure or even enable an attacker to execute arbitrary code on the victim\u2019s system.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-6034
\nSeverity: High (7.8 CVSS Score)
\nAttack Vector: Local file
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: Potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

NI Circuit Design Suite | 14.3.1 and prior versions<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability is exploited when a user opens a specially crafted .sym file in the SymbolEditor component of the NI Circuit Design Suite. Upon opening of the malicious file, an out-of-bounds read occurs in the DefaultFontOptions() function, leading to memory corruption. This corruption potentially allows the attacker to disclose sensitive information or execute arbitrary code on the user’s system.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual representation of how the vulnerability might be exploited. This pseudocode demonstrates the loading of a malicious .sym file leading to an out-of-bounds read.<\/p>\n

load_sym_file('malicious.sym') {\nread_file('malicious.sym');\ncorrupt_memory(DefaultFontOptions());\nexecute_arbitrary_code();\n}<\/code><\/pre>\n
Mitigation Guidance<\/strong><\/p>\n
Users are advised to apply the vendor-supplied patch as soon as possible to fix this vulnerability. In the interim, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. Always be cautious when opening .sym files, especially those received from unknown sources.<\/p>\n","protected":false},"excerpt":{"rendered":"
