CVE-2023-7311 is a command injection vulnerability in BYTEVALUE Intelligent Flow Control Router. The flaw is present in the /goform/webRead/open endpoint, where the path parameter is not properly validated and is incorporated into a shell execution context. Because attacker-controlled input is echoed into that shell context without sufficient sanitization, a remote attacker can inject arbitrary shell commands and cause them to execute on the device operating system. The available reporting indicates that successful exploitation can result in installation of backdoors, privilege escalation on the host, and full compromise of the router and its management functionality. VulnCheck has also observed exploitation activity associated with the RondoDox botnet campaign.
