ABB is currently investigating an improper input validation vulnerability and recommends users follow certain guidelines until a corrected version is available for its Panel Builder 800, according to a report with NCCIC.

An attacker could exploit the vulnerability by tricking a user to open a specially crafted file, allowing the attacker to insert and run arbitrary code. This vulnerability requires user interaction, and the exploit is only triggered when a local user runs the affected product and loads the specially crafted file.
