TITLE

TwinCAT Scope 'TCatScopeView.exe' Heap Buffer Overflow Vulnerability

Trust: 0.8

DESCRIPTION

TwinCAT is an industrial automation product. TwinCAT has a security hole that allows malicious users to control the application. The TCatScopeView.exe tool has an error when processing the Scope view file. The attacker builds a specially crafted SVW file to trick the user into parsing, triggering a heap-based buffer overflow, and successfully exploiting the vulnerability to execute arbitrary code in the application context. TwinCAT Scope is prone to a heap-based buffer-overflow vulnerability because it fails to properly validate user-supplied input. Failed exploit attempts will likely result in a denial-of-service condition. TwinCAT Scope 2.9.0.226 is vulnerable; other versions may also be affected
