We will update this page when the fix is ready (I expect that in the next 3-4 weeks). We now have content online () documenting the vulnerability and relevant steps for mitigation. that advises users how to safely inspect files they aren’t sure about.Īdditionally, we’ve been working internally to determine the best way to address the vulnerability, the scope of the implications, and the best timeline in which to move forward. I also want ensure your readers are aware of this helpful public documentation. For these reasons, we’re confident in our revised security score of 5.3. Further, turning zeros in memory into code execution is difficult, as confirmed by Mitre, and the file loading function cannot be invoked remotely because it is not bound to the network stack. The vulnerability writes zeroes to memory, not data or arbitrary code like the. Our team has been looking into this and our understanding is that Cisco Talos demonstrated a crash in LabVIEW and not errant code execution. I’m in the Product Marketing department at NI and am directly responsible for LabVIEW. The consequences of a successful compromise of a system that interacts with the physical world, such as a data acquisition and control systems, may be critical to safety,” Lee said. “As with the previous disclosure, organizations should be aware that proprietary file formats without a published specification are nevertheless amenable to inspection to identify vulnerabilities. In that instance, National Instruments released a patch, LabVIEW 2016 f2. ![]() In March, Cisco Talos disclosed a similar memory corruption vulnerability (CVE-2017-2775) to National Instruments which was triggered by opening specially crafted VI files. exe files and should be accorded the same security requirements,” Lee said. “Many (LabVIEW) users may be unaware that VI files are analogous to. NET Framework 1.0, 1.1, and 2.0 for Windows 2000, XP, Server 2003 and Vista. In that instance, remote attackers could execute arbitrary code via what was most likely was a buffer overflow attack involving an “unchecked buffer” and un-validated message lengths in the PE Loader services in Microsoft. NET PE loader vulnerability ( CVE-2007-0041) patched by Microsoft in 2007. Lee disagrees with that assessment and compared the risk associated with bug to that of a critical. exe like file format can be modified to replace legitimate content with malicious and has declined to release a patch,” according to the Cisco Talos report. “National Instruments does not consider that this issue constitutes a vulnerability in their product, since any. Under these conditions an attacker could craft a Virtual Instrument file (.vi) that can be used to trigger the vulnerability, potentially resulting in code execution. Modulating the values within this section of a VI file can cause a controlled looping condition resulting in an arbitrary null write,” according to Martin Lee, technical lead, security research, with Cisco Talos. “Although there is no published specification for the file format, inspecting the files shows that they contain a section named ‘RSRC’, presumably containing resource information. Researchers linked the flaw to an exploitable memory corruption bug that exists in the RSRC segment parsing functionality of LabVIEW’s software. “Talos is disclosing the presence of a code execution vulnerability which can be triggered by opening specially crafted VI (virtual instrument) files, the proprietary file format used by LabVIEW,” wrote Cisco Talos in a research note posted earlier this week. The vulnerability (CVE-2017-2779) was discovered by Cisco Talos and disclosed to National Instruments in January and impacts LabVIEW 2016 version 16.0. The affected software is LabVIEW, a leading program designed for rapid development of engineering applications that require testing, measurement or control. Automated test equipment and virtual instrumentation software behemoth National Instruments said it will not patch software that security researchers at Cisco Talos said is flawed and could result in code execution by third-party attackers. ![]()
