EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under NVD CVSS v3. EPSS exploit probability: 1.9%, top 22% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

BYTEVALUE Intelligent Flow Control Router contains a command injection vulnerability via the /goform/webRead/open endpoint. The path parameter is not properly validated and is echoed into a shell context, allowing an attacker to inject and execute arbitrary shell commands on the device. Successful exploitation can lead to writing backdoors, privilege escalation on the host, and full compromise of the router and its management functions. VulnCheck has observed this vulnerability being targeted by the RondoDox botnet campaign.
