CVE-2021-44675Known exploitationNetwork attack vector

Unauthenticated code execution via misconfigured filter

Published Dec 20, 2021 · Updated Aug 4, 2024

Authentication bypass in Zoho ManageEngine ServiceDesk Plus MSP before 10.5 Build 10534 allows remote attackers to execute arbitrary code. A list-view state-handling filter is misconfigured, so a crafted URL reaches an authenticated endpoint without enforcing authentication. No credentials or user interaction are required, and successful exploitation permits arbitrary code execution and subsequent attacks.
