Database Open Access Vulnerability

Vulnerability Title: Database Open Access

Service Port: Database Listener Port

Service Name: Oracle TNS Listener

Service Protocol: tcp

Vulnerability Description: 

The database allows any remote system the ability to connect to it. It is recommended to limit direct access to trusted systems because databases may contain sensitive data, and new vulnerabilities and exploits are discovered routinely for them. For this reason, it is a violation of PCI DSS section 1.3.6 to have databases listening on ports accessible from the Internet, even when protected with secure authentication mechanisms.

Solution:

Configure the database server to only allow access to trusted systems. For example, the PCI DSS standard requires you to place the database in an internal network zone, segregated from the DMZ

Add VALIDNODE_CHECKING in sqlnet.ora file and add IPs to restrict database access and then reload the listener and check:

$ORACLE_HOME/network/admin/sqlnet.ora

tcp.validnode_checking = yes

tcp.invited_nodes =(*.*.*.*)

Self-signed TLS/SSL certificate Vulnerability - Weblogic 12.2.1.4

Vulnerability Title: Self-signed TLS/SSL certificate

Service Port:4443

Service Name: HTTPS

Service Protocol: tcp

Vulnerability Description: 

The server's TLS/SSL certificate is self-signed. Self-signed certificates cannot be trusted by default, especially because TLS/SSL man-in-the-middle attacks typically use self-signed certificates to eavesdrop on TLS/SSL connections.

Solution:

Obtain a new TLS/SSL server certificate that is NOT self-signed and install it on the server or remove the demo certificates.

remove these demo.cert and DemoTrust.jks certificates and check:

$MWH/wlserver/server/lib/DemoTrust.jks

$MWH/wlserver/server/lib/demo.cert

Click Jacking Vulnerability - Weblogic 12.2.1.4

Vulnerability Title: Click Jacking

Service Port:4443

Service Name: HTTPS

Service Protocol: tcp

Vulnerability Description: 

Clickjacking, also known as a UI redress attack, is a method in which an attacker uses multiple transparent or opaque layers to trick a user into clicking a button or link on a page other than the one they believe they are clicking. Thus, the attacker is "hijacking" clicks meant for one page and routing the user to an illegitimate page.

Vulnerability Solution:Use HTTP X-Frame-Options. Send the HTTP response headers with X-Frame-Options that instruct the browser to restrict framing where it is not allowed.

 

1. Apply the Patch 30418565

 Patch 30418565 FORMS LISTENER SERVLET NOT GENERATING X-FRAME-OPTIONS HTTP HEADER

 

Add SAMEORIGIN option with X-Frame-Options optin in Run-time and Staging httpd.conf

--  X-Frame-Options is available at line 1033

Header always append X-Frame-Options SAMEORIGIN

2.Run-time directory:

$DOMAIN_HOME/config/fmwconfig/components/OHS/instances/<componentName>/httpd.conf

3.Staging directory:

$DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/httpd.conf

Restart the service and check.

Browsable Web Directory Vulnerability - Weblogic 12.2.1.4

Vulnerability Title:Browsable web directory 

Service Port:4443

Service Name:HTTPS

Service Protocol:tcp

Vulnerability Description: A web directory was found to be browsable, which means that anyone can see the contents of the directory. These directories can be found: 

 * via page spidering (following hyperlinks), or

 * as part of a parent path (checking each directory along the path and searching for ""Directory Listing"" or similar strings), or

 * by brute forcing a list of common directories.

 Browsable directories could allow an attacker to perform a directory traversal attack by viewing ""hidden"" files in the web root, including CGI scripts, data files, or backup pages."

Vulnerability Proof: https://<*.*,*.*>:4443/OracleHTTPServer12c_files/ 

Solution:

Remove the "Indexs" option from Run-time & Staging httpd.conf 

--check @ line # 241

From: Options Indexes FollowSymLinks

To: Options FollowSymLinks

1.Run-time directory:

$DOMAIN_HOME/config/fmwconfig/components/OHS/instances/<componentName>/httpd.conf

2.Staging directory:

$DOMAIN_HOME/config/fmwconfig/components/OHS/<componentName>/httpd.conf

You should add the following value in [default] section of the formsweb.cfg

3.$DOMAIN_HOME/config/fmwconfig/servers/WLS_FORMS/applications/formsapp_12.2.1/config/formsweb.cfg

#

#X-Frame-Options to Resolve Click-Jacking

#

Set_X_Frame_Options=true

If you are not planing for https then comment out these lines in both Run-time and Staging httpd.conf files:

# Include the SSL definitions and Virtual Host container

include "ssl.conf"------------------------------->Comment out this.

....

IncludeOptional "moduleconf/*.conf" ------------------------------->Comment out this.

Restart the services and then test.

Weblogic 12.2.1.4 Admin Server Default Port Change

 

Please make the below changes to update the port in FMW 12.2.1.4:

Step 1: Take the backup of the below files:

$DOMAIN_HOME/config/fmwconfig/servers/AdminServer/applications/em/META-INF/emoms.properties

$DOMAIN_HOME/sysman/state/targets.xml

$DOMAIN_HOME/bin/stopManagedWebLogic.sh

$DOMAIN_HOME/bin/startManagedWebLogic.sh

$DOMAIN_HOME/bin/stopWebLogic.sh

Step 2: Navigate to the Weblogic Admin Console > Environments > Servers > AdminServer > Configuration Tab > General Sub Tab > now change the listen port from 7001 to 7010 and save the changes

Step3: Update the Admin Port(7001 to 7010) in the below files:

$DOMAIN_HOME/config/fmwconfig/servers/AdminServer/applications/em/META-INF/emoms.properties

$DOMAIN_HOME/sysman/state/targets.xml

$DOMAIN_HOME/bin/stopManagedWebLogic.sh

$DOMAIN_HOME/bin/startManagedWebLogic.sh

$DOMAIN_HOME/bin/stopWebLogic.sh

Step 4: Run $DOMAIN_HOME/bin/setDomainEnv.sh

Step 5: Restart your Admin Server and test the Weblogic Console URL and EM Console URL.
