CVE-2019-16283

Local privilege escalation via undisclosed installer flaw

Published Jun 9, 2023 · Updated Jan 6, 2025

Code injection in HP SoftPaq Installer 4.0.100.1189 allows local users to execute arbitrary code through a vulnerable installer. HP identifies the affected locus as the stub32i.exe installer but has not published the operation that mishandles attacker-controlled input. Exploitation requires local low-privileged access and can elevate privileges, enabling data disclosure, modification, and service interruption in the installer's security context.
