CVE-2025-7766

Unauthenticated code execution via device-supplied XML entities

Published Jul 22, 2025 · Updated Jul 23, 2025

XXE in Lantronix Provisioning Manager 7.10.2 and earlier allows remote attackers to execute code through device-supplied configuration files. The application parses configuration XML received from managed network devices without restricting external entity resolution. Exploitation requires a malicious or impersonated device on a reachable subnet and passive interaction when the operator processes its configuration.
