CVE-2020-23826Public exploitNetwork attack vector

Authenticated command execution via HTTP API

Published Jan 22, 2021 · Updated Aug 4, 2024

Command injection in Yale WIPC-303W 2.21 through 2.31 allows remote authenticated users to execute commands through its HTTP API. Public sources do not disclose the endpoint, parameter, or command-building operation that fails to neutralize input. Successful requests run commands with the camera service's privileges; the record is disputed as a possible duplicate of a WIPC-301W report.
