CVE-2022-28687

Code execution via unsecured APP-file library search

Published Mar 29, 2023 · Updated Feb 18, 2025

Uncontrolled DLL search in AVEVA Edge 2020 SP2 Patch 0 (4201.2111.1802.0000) allows remote attackers to execute code via a crafted APP file. When Edge handles the APP file, its process searches an unsecured location and loads an attacker-supplied library instead of a trusted DLL. Execution requires the target to visit a malicious page or open a malicious file and runs with the current process privileges.
