CVE-2020-7874Network attack vector

Arbitrary code execution via unvalidated plug-in download

Published Sep 9, 2021 · Updated Aug 4, 2024

Code download without integrity checks in TOBESOFT Nexacro Platform 14 before 14.0.1.3600 allows remote attackers to execute arbitrary files. The NEXACRO14 Runtime ActiveX control incompletely validates a new plug-in's download URL or file extension before loading the retrieved file. Exploitation requires user interaction on Windows and can run attacker-supplied code with the affected runtime's privileges.
