Impact

A flaw in the Administration WebUI of the Waterfall WF‑500 TX Host allows remote authenticated attackers to inject arbitrary operating system commands. The vulnerability, identified as CWE‑78, gives attackers the ability to run commands with the privileges of the web service, potentially leading to full system compromise, data theft, or disruption. This can affect confidentiality, integrity, and availability of the host and any connected assets.

Affected Systems

The affected product is Waterfall WF‑500 TX Host, version 7.9.1.0 R2502171040. The issue is limited to this specific build and is not present in earlier or newer releases that have addressed the injection flaw.

Risk and Exploitability

The CVSS score of 8.5 indicates a high severity risk. EPSS data is not available, so the exploitation probability cannot be quantified, but the lack of a KEV listing suggests no widespread active exploitation is documented. The likely attack vector is over the network via the web UI, requiring valid authentication, after which an attacker can execute system commands.

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update to a patched version of the Waterfall WF‑500 TX Host that removes the OS command injection flaw.
  • If a patch is not immediately available, limit WebUI access to a secure internal network and enforce strong authentication mechanisms to reduce exposure.
  • Disable or restrict the Administration WebUI for non‑administrative users or temporarily shut down the service until the patch is applied.
