CVE-2019-20046Network attack vector

Unauthenticated code execution via missing authentication

Published Feb 14, 2020 · Updated Aug 5, 2024

Authentication bypass in HUSKY RTU 6049-E70 firmware 5.0 and prior allows remote attackers to read sensitive information or execute arbitrary code. The RTU accepts control access without adequate authentication, exposing command functions and protected data to unauthenticated network requests. Any network-reachable device can be targeted without credentials, potentially disclosing sensitive information or executing code remotely.
