CVE-2023-4601 in System Configuration
Summary
by MITRE • 10/25/2023
A stack-based buffer overflow vulnerability exists in NI System Configuration that could result in information disclosure and/or arbitrary code execution. Successful exploitation requires that an attacker can provide a specially crafted response. This affects NI System Configuration 2023 Q3 and all previous versions.

The vulnerability identified as CVE-2023-4601 represents a critical stack-based buffer overflow in National Instruments System Configuration software, specifically impacting version 2023 Q3 and all preceding releases. This flaw resides within the software's handling of specially crafted input responses, creating a pathway for malicious actors to exploit the system through carefully constructed data inputs. The vulnerability's classification as stack-based indicates that the overflow occurs within the program's stack memory region, where function call information and local variables are stored, making it particularly dangerous due to the potential for direct memory corruption and execution control.
The technical implementation of this vulnerability stems from inadequate input validation mechanisms within the NI System Configuration application, which fails to properly bounds-check data received from external sources or user-provided responses. When the application processes malformed or oversized input data, it writes beyond the allocated buffer space on the stack, potentially overwriting adjacent memory locations including return addresses, function pointers, and other critical program state information. This memory corruption can lead to unpredictable behavior, application crashes, or more severely, allow attackers to execute arbitrary code with the privileges of the affected process.
The operational impact of this vulnerability extends beyond simple system instability to encompass serious security implications including unauthorized information disclosure and complete system compromise. An attacker who successfully exploits this vulnerability could gain access to sensitive system information, escalate privileges, or execute malicious code within the context of the NI System Configuration application. The requirement for an attacker to provide a specially crafted response suggests that this vulnerability may be exploitable through social engineering or targeted attacks rather than automated scanning, but the potential for remote code execution remains significant given the right conditions. The vulnerability affects organizations using National Instruments hardware and software solutions, particularly those in industrial control systems, automation environments, and scientific instrumentation where the affected software may be deployed.
Mitigation strategies for CVE-2023-4601 should prioritize immediate software updates from National Instruments to address the identified buffer overflow issue, as the vendor has likely released patches or updates to correct the input validation flaws. Organizations should also implement network segmentation and access controls to limit exposure of affected systems, particularly in environments where the software handles sensitive data or operates in critical infrastructure settings. Additional defensive measures include deploying intrusion detection systems to monitor for suspicious network activity and implementing application whitelisting to prevent execution of unauthorized code. This vulnerability aligns with CWE-121 stack-based buffer overflow category and maps to ATT&CK techniques involving code injection and privilege escalation, making it particularly concerning for organizations following security frameworks that emphasize protecting against persistent threats in industrial environments. The remediation process should include thorough testing of patches in controlled environments before deployment to ensure compatibility with existing system configurations and workflows.
