Unauthenticated code execution via injection
Published Dec 8, 2021 · Updated Aug 4, 2026
A code injection vulnerability in Ivanti Endpoint Manager Cloud Service Appliance 4.6.0-512 allows remote attackers to execute arbitrary code via a network request. The vulnerable CSA input is processed as executable code instead of being safely constrained, allowing attacker-controlled instructions to run with the limited nobody account. No authentication or user interaction is required; exploitation can expose, alter, or interrupt appliance services, and CISA lists the flaw as exploited in the wild.
