我在哪里可以找到ESAPI.properties？

Question

Am trying to use OWASP ESAPI library in my web app to escape request parameters in JSPs as below ESAPI.encoder().encodeForHTML(request.getParameter()).

I have added esapi-2.1.0.jar under WEB-INF/lib but I get the below exception

org.owasp.esapi.errors.ConfigurationException: ESAPI.properties could not be loaded by any means. Fail. org.owasp.esapi.reference.DefaultSecurityConfiguration.loadConfiguration(DefaultSecurityConfiguration.java:439)

But I couldnt find ESAPI.properties in the JAR file. Any idea where I can get this? Also where should I place this properties file? Please help.

Answer 1

Here is the reference: ESAPI installation guide .

You can download ESAPI.properties from here .

You can create ESAPI.properties file yourself and place the same content there. It should be placed in your 'src/main/resources' folder.

Also you will need validation.properties file to handle XSS, which should be placed in 'src/test/resources' folder.

Please make sure to change the application name in these properties file to your application as in

Validator.Redirect=^\\/test.*$

test should be replaced with your application name.

I was looking for the same file as while deploying my webapp I was getting -

Mar 08, 2017 1:23:12 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [mvc-dispatcher] in context with path [/WebDynamo] threw exception [org.owasp.esapi.errors.ConfigurationException: java.lang.reflect.InvocationTargetException SecurityConfiguration class (org.owasp.esapi.reference.DefaultSecurityConfiguration) CTOR threw exception.] with root cause
java.lang.IllegalArgumentException: Failed to load ESAPI.properties as a classloader resource.
    at org.owasp.esapi.reference.DefaultSecurityConfiguration.loadConfigurationFromClasspath(DefaultSecurityConfiguration.java:667)

Anyway for my webapp I just added ESAPI.properties in source root folder (src folder) (don't add it in any package) . And the file is just empty. And web app works just fine. I see following logs in the webapp so if you are ever wondering where this file is being searched then refer this -

I am sure these are configurable and other files too you can add it src folder. Also I found this file in -

https://github.com/OWASP/EJSF/blob/master/esapi_master_FULL/WebContent/ESAPI.properties

The file is pretty big to paste it's contents here but based on default values it is setting as per logs above following things are required -

ESAPI.printProperties=true
Encryptor.CipherTransformation=AES/CBC/PKCS5Padding
ESAPI.Encoder=org.owasp.esapi.reference.DefaultEncoder
# Log4JFactory Requires log4j.xml or log4j.properties in classpath - http://www.laliluna.de/log4j-tutorial.html
ESAPI.Logger=org.owasp.esapi.reference.Log4JLogFactory
# Determines whether ESAPI should log the application name. This might be clutter in some single-server/single-app environments.
Logger.LogApplicationName=true
# Determines whether ESAPI should log the server IP and port. This might be clutter in some single-server environments.
Logger.LogServerIP=true
# Set the application name if these logs are combined with other applications
Logger.ApplicationName=ExampleApplication

Ok since the above links are all broken or will be outdated in a while (eg link to a specific version) here is the Github Link:
