A CWE-426: Untrusted Search Path vulnerability exists in Vijeo Designer Basic (V1.1 HotFix 15 and prior) and Vijeo Designer (V6.9 SP9 and prior), which could cause arbitrary code execution on the system running Vijeo Basic when a malicious DLL library is loaded by the Product.

Extended Description

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
