Original NVD Description

An insecure process execution vulnerability exists in the pc-printer-updater.exe component of the PaperCut Print Deploy Client for Windows. The application, which typically operates with high-level system privileges, attempts to perform an internal validation check by invoking a secondary system utility using an unqualified file reference. Because the application does not specify an absolute path to this utility, it relies on the operating system's default search order to locate the executable. Under specific conditions, a local attacker with the ability to modify directories within the system's search path could plant a malicious binary that mimics the expected utility. This could result in the malicious code being executed with SYSTEM privileges, leading to a full compromise of the affected host.
