CVE-2024-7443Network attack vector

Remote command execution via QUERY_STRING injection

Published Aug 3, 2024 · Updated Aug 5, 2024

Command injection in VIVOTEK IB8367A VVTK-0100b allows remote authenticated users to execute commands via QUERY_STRING. The upload_file.cgi handler uses getenv to read QUERY_STRING and processes the unneutralized value in a command context. Access to the vulnerable CGI endpoint is required; successful exploitation can read, alter, or interrupt camera data and operation.
