Authentication Bypass in Quest KACE Systems Management Appliance SSO
CVE-2025-32975 is a critical improper authentication vulnerability in Quest KACE Systems Management Appliance (SMA) affecting the SSO authentication handling mechanism. The flaw allows a remote, unauthenticated attacker to impersonate legitimate users, including administrators, without supplying valid credentials. Available reporting indicates the issue stems from improper validation of authentication tokens or session state during the SSO process, causing the appliance to process requests as authenticated when credential verification has not actually occurred. On successful exploitation, an attacker can obtain administrative access to the SMA and use built-in management functionality to execute commands, deploy software, and alter configurations across managed endpoints. Observed exploitation in the wild has been associated with rapid administrative takeover of internet-exposed, unpatched SMA instances.
