CVE-2026-78632: Okta RADIUS Agent insecure file permissions in Windows installer

CVE-2026-78632 · Severity: medium · CVSS 5.3 · Published 2026-10-13

The Okta RADIUS Agent Windows installer improperly sets file permissions on directories containing encryption keys and API tokens, allowing any local service account on the host to read sensitive credentials. An attacker with local access and the ability to run code as a service account can extract the AES encryption key and encrypted Okta API token, potentially enabling account compromise or lateral movement in enterprise environments.

Vendors: Okta.

Technical details

The vulnerability stems from insecure default file permissions (CWE-732) assigned by the Windows installer to NT SERVICE\ALL SERVICES and CREATOR OWNER on directories containing agent configuration, AES encryption keys, and logs. This allows any local service account to read the encrypted Okta API token and encryption keys. Exploitation requires local authenticated access and the ability to execute code in a Windows service account context.
