CVE-2025-13659Network attack vector

Remote code execution via arbitrary file write

Published Dec 9, 2025 · Updated Feb 26, 2026

Arbitrary file write in Ivanti Endpoint Manager before 2024 SU4 SR1 allows remote attackers to execute code on the server through a crafted file. The public record does not identify the affected function or explain how attacker-controlled content reaches a server path, but it maps the outcome to web-shell upload. Exploitation requires no authentication but does require user interaction; a successful write can place executable content and compromise the server.
