Vulnerability identifier: #VU8033
CSH Severity: High
CVSS v4.0: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber
CVE-ID: CVE-2017-2779
CWE-ID: CWE-787
Exploitation vector: Remote access
Exploit availability:
No public exploit available
Vendor: National Instruments
Affected software:
LabVIEW
LabVIEW
Detailed vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code execution.
The weakness exists in the RSRC segment parsing functionality of LabVIEW due to out-of-bounds write when parsing of virtual instrument (VI) files. A remote attacker can send a specially crafted VI file, trick the victim into opening it, cause a controlled looping condition, trigger arbitrary null write and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
