CVE-2025-13662

Code execution via unverified HIIDriver signatures

Published Dec 9, 2025 · Updated Feb 26, 2026

Improper signature verification in Ivanti Endpoint Manager before 2024 SU4 SR1 allows remote attackers to execute arbitrary code. The HIIDriver class in the patch management component accepts configuration data without properly validating its cryptographic signature. Exploitation requires a user to visit a malicious page or open a malicious file; administrative application access removes that interaction gate, and code runs as the current user or service account.
