I use Spring Security 3.1.4 to secure a Spring MVC 3.2.4 application deployed to Tomcat. I have the following Spring Security configuration:
<http auto-config="true" use-expressions="true">
<http-basic />
<logout ... />
<form-login ... />
<intercept-url pattern="/" access="isAnonymous() or hasRole('ROLE_USER')" />
<intercept-url pattern="/about" access="isAnonymous() or hasRole('ROLE_USER')" />
<intercept-url pattern="/login" access="isAnonymous() or hasRole('ROLE_USER')" />
<intercept-url pattern="/under-construction" access="isAnonymous() or hasRole('ROLE_USER')" />
<intercept-url pattern="/admin-task*" access="hasRole('ROLE_USER') and hasRole('ROLE_ADMINISTRATOR')" />
<intercept-url pattern="/resources/**" access="isAnonymous() or hasRole('ROLE_USER')" />
<intercept-url pattern="/**" access="hasRole('ROLE_USER')" />
</http>
I noticed that URL patterns without a trailing slash (e.g., /about) do not match URLs with a trailing slash (e.g., /about/) and vice-versa. In other words, a URL with a slash and an identical URL without a slash are treated as two different URLs by Spring Security. The problem could be fixed by using two security rules:
<intercept-url pattern="/about" access="isAnonymous() or hasRole('ROLE_USER')" />
<intercept-url pattern="/about/" access="isAnonymous() or hasRole('ROLE_USER')" />
Is there a better solution?
I know that path-type="regex" allows to define URL patterns with regular expressions, but I would like to avoid any unnecessary complexity if it's possible.
Update
As Adam Gent noted, there is an additional problem that involves URLs with a dot: /about.foo and /about are treated as the same URL by Spring MVC. However, Spring Security treats them as two different URLs. So, one more security rule may be necessary:
<intercept-url pattern="/about.*" .../>
Spring Security 4.1+
Spring Security has now added a new matcher which is aware of your Spring MVC URL matching configuration. This tells Spring Security to match paths based on the same rules that Spring MVC uses, eliminating the possibility of a URL being valid, but unsecured.
First you need to replace any old matchers with the new MVC matcher. Spring Security is now in sync with however you have configured Spring MVC so you are free to add or remove any path matching configuration. I recommend sticking with the defaults where possible.
Java Config
If you were using antMatchers, you now should use mvcMatchers:
protected configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.mvcMatchers("/about").hasRole("USER");
}
XML Config
You need to add the attribute request-matcher to your http tag:
<http request-matcher="mvc">
<intercept-url pattern="/about" access="hasRole('USER')"/>
</http>
Full Reference
Please note that you also should no longer be prefixing your roles with "ROLE_" as Spring Security does this for you automatically.
Spring Security Before 4.1
I've not been able to find a way to handle both trailing slash and path suffixes in Spring Security. Obviously it is possible to write a regexp to handle these cases but this seems to make the security rules overly complex and prone to error. I want to be as confident as possible that I'm not exposing resources accidentally.
Therefore, my approach is to disable this behaviour in Spring by configuring the path matcher to be strict about both trailing slashes and suffixes.
Java Config
#Configuration
public class ServletConfig extends WebMvcConfigurerAdapter {
#Override
public void configurePathMatch(final PathMatchConfigurer configurer) {
configurer.setUseSuffixPatternMatch(false);
configurer.setUseTrailingSlashMatch(false);
}
}
XML Config
<mvc:annotation-driven>
<mvc:path-matching suffix-pattern="false" trailing-slash="false" />
</mvc:annotation-driven>
<intercept-url pattern="/about/**"...
also works for me in Spring Security 3.1.4.
This secures /about, /about/, and /about/anything_else
I have used separate patterns for the same url. It is working for Spring security 3.1.7.RELEASE
<security:intercept-url pattern="/mypage./**" access="hasAnyRole('admin','reportviewer')"/>
<security:intercept-url pattern="/mypage" access="hasAnyRole('admin','reportviewer')"/>
<security:intercept-url pattern="/mypage/**" access="hasAnyRole('admin','reportviewer')"/>

I need to apply a Filter to facilitate setting the request.setCharacterEncoding("UTF-8") before first use of the request.getParameter(), otherwise my parameters are read as ISO_8859_1, setting it later does not work.
Unfortunately the 1st 'reading' filter is the Spring (4.3.13.RELEASE) Security 'CsrfFilter' & I'm unable to set a filter before it.
I'm using a minimal (no login required) spring security chain defined by:
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/**" access="hasRole('ROLE_ANONYMOUS')" />
<access-denied-handler ref="myAccessDeniedHandler"/>
</http>
The whole application works except for reading characters outside of ISO_8859_1, I need full UTF-8 support. Ive confirmed the network traffic is UTF. But is popping out of the request.getParameter() calls as ISO_8859_1.
My solution was to add a Spring GenericFilterBean as below.
<http>
<custom-filter after="FIRST" ref="utf8Filter" />
</http>
<beans:bean id="utf8Filter" class="my.SetRequestEncodingFilter"/>
But this generates a run time startup exception.
Caused by: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: No AuthenticationEntryPoint could be established. Please make sure you have a login mechanism configured through the namespace (such as form-login) or specify a custom AuthenticationEntryPoint with the 'entry-point-ref' attribute
I'm unable to find a security chain setup that allows inclusing of a filter (but needs to before the csf filter).
I'm thinking this is really a CsrfFilter bug'et, but it shouldnt be compromising subsequent getParameter() usage - but I dont really want to go there.
I tried the following - same result
<http auto-config="true" use-expressions="true" entry-point-ref="http403EntryPoint">
<intercept-url pattern="/**" access="hasRole('ROLE_ANONYMOUS')" />
<access-denied-handler ref="myFormAccessDeniedHandler"/>
</http>
<beans:bean id="http403EntryPoint" class="org.springframework.security.web.authentication.Http403ForbiddenEntryPoint">
</beans:bean>
Any suggestions?
You can explicitly give default character encoding to be used by application by giving following argument at run time of application:
-Dfile.encoding=UTF-8
Since you're running Tomcat, you can just configure the input encoding in server.xml at the HTTP Connector like this:
<Connector port="8080" protocol="HTTP/1.1"
URIEncoding="UTF-8"
... >
Adding a WebApplicationInitializer seems to have resolved the issue without the need to worry about the servlet chain. I also didnt have to touch my web.xml.
public void onStartup(ServletContext servletContext) throws ServletException {
FilterRegistration.Dynamic encodingFilter = servletContext.addFilter("encoding-filter", new CharacterEncodingFilter());
encodingFilter.setInitParameter("encoding", "UTF-8");
encodingFilter.setInitParameter("forceEncoding", "true");
encodingFilter.addMappingForUrlPatterns(null, false, "/*");
}
Fairly new to Spring, so this may be basic.
We've recently transitioned from Spring 3 to 4 and running into some header issues with the new defaults tied to one of our partners business logic
We would like to keep the defaults everywhere except for a specific URL "/stg/strategem/strg/drammin.syg"
Currently we have:
<http use-expressions="true" entry-point-ref="web.AuthenticaionEntryPoint">
<intercept-url pattern="/admin/**" access = "hasAnyRole('GKR_ADMIN', 'GKR_ADMIN_ADV')"/>
<intercept-url pattern="/**" access = "hasAnyRole('GKR_USER')"/>
</http>
How can I configure this so that ["/stg/strategem/strg/drammin.syg"] is still secured but is the only place where the below header configuration applies?
<headers defaults-disabled="true">
<content-type-options />
<hsts include-subdomains="true" max-age-seconds="31536000"/>
<frame-options policy="SAMEORIGIN"/>
<xss-protection block="false"/>
</headers>
UPDATE 1: Was able to make the URL I need headerless more specific
UPDATE 2:
I just tried adding another http block, but I keep getting the Spring Error
A universal match pattern ('/**')
is defined before other patterns in the filter chain, causing them to be ignored.
Regardless of what order I put these blocks in, I've even tried removing the "/**" pattern, this error still comes up.
My attempt:
<http use-expressions="true" entry-point-ref="web.AuthenticaionEntryPoint">
<intercept-url pattern="/admin/**" access = "hasAnyRole('GKR_ADMIN', 'GKR_ADMIN_ADV')"/>
<intercept-url pattern="/**" access = "hasAnyRole('GKR_USER')"/>
</http>
<http use-expressions="true" entry-point-ref="web.AuthenticaionEntryPoint">
<headers defaults-disabled="true">
<content-type-options />
<hsts include-subdomains="true" max-age-seconds="31536000"/>
<frame-options policy="SAMEORIGIN"/>
<xss-protection block="false"/>
</headers>
<intercept-url pattern="/stg/strategem/strg/drammin.syg" access = "hasAnyRole('GKR_ADMIN', 'GKR_ADMIN_ADV', 'GKR_USER')"/>
</http>
UPDATE 3: Was able to find a solution, check it out in the Answers
You should be able to have multiple <http> blocks with different configuration for each. See Spring Security Reference - Multiple Security
Alright folks, I was able to get this working by using a separate HTTP block that had a pattern, but no intercept URL. Trying to make both have security configurations was what caused the issue.
Thanks Zilvinas for pointing me down the right path.
The first block applies header configs to just the specific url. Everything else gets Spring's defaults.
The second block applies security measures. (including to the specific url since I have a /** wildcard)
<http pattern="/stg/strategem/strg/drammin.syg">
<headers defaults-disabled="true">
<content-type-options />
<hsts include-subdomains="true" max-age-seconds="31536000"/>
<frame-options policy="SAMEORIGIN"/>
<xss-protection block="false"/>
</headers>
</http>
<http use-expressions="true" entry-point-ref="web.AuthenticaionEntryPoint">
<intercept-url pattern="/admin/**" access = "hasAnyRole('GKR_ADMIN', 'GKR_ADMIN_ADV')"/>
<intercept-url pattern="/**" access = "hasAnyRole('GKR_USER')"/>
</http>
I don't know how to configure spring security to specify different ROLEs for overlaping URLs.
<sec:intercept-url pattern="/app/ws**" access="ROLE_WEBSERVICE"/>
<sec:intercept-url pattern="/app**" access="ROLE_ADMIN"/>
I need to accept user with role ROLE_WEBSERVICE on /app/ws** even if this user does not have user ROLE_ADMIN.
Could you point me to the correct place of documentation? I could not find it. Thanks.
If you switch to an expression rule instead of the vanilla RoleVoter you get more flexibility, e.g.
<http use-expressions="true">
...
<intercept-url pattern="/app/ws**" access="hasRole('ROLE_WEBSERVICE') and hasRole('ROLE_ADMIN')"/>
<intercept-url pattern="/app**" access="hasRole('ROLE_ADMIN')"/>
...
what is the use of auto-config=true in spring security.
In which scenario we should use this.
what is the actual use of using auto-config=true ?
auto-config="true" is equivalent to:
<http>
<form-login />
<http-basic />
<logout />
</http>
so it gives you a very basic security configuration to boot.
Source: https://docs.spring.io/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ns-auto-config
auto-config='true' means
for the intercept-url pattern the spring security provides the default login screen
This is one of the cases where we use auto-config = true:
<http auto-config='true'>
<intercept-url pattern="/**" access="ROLE_USER" />
</http>
This declaration means we want all URLs within our application to be secured, requiring the role ROLE_USER to access them. The element is the parent for all web-related namespace functionality. The element defines a pattern which is matched against the URLs of incoming requests using an ant path style syntax
Spring Security Reference:
"Use of this attribute is not recommended. Use explicit configuration elements instead to avoid confusion."

I have a java web application running on Tomcat 7.
I am using Spring 3.2 with Spring Security 3.1 on the backend, and am exposing an API via RESTful URLs following the /api/** pattern.
The UI for the web application is built using BackboneJS. I am using Backbone models mapped directly to the RESTful URLS.
The UI is locked down using form-login authentication, so the user is always redirected to the login screen if they have are not currently authenticated.
I am now attempting to expose the same RESTful URLs to another external service using http-basic authentication. Unfortunately, when securing the same URL pattern, it seems Spring will not allow me to use more than one filter chain. Whichever is defined first in the configuration file seems to take precedence.
I would hate to have to map to separate URL patterns for the same RESTful resources, but it seems like I may not have a choice.
Here is the important sample of my (currently broken) spring security configuration:
<!-- configure basic http authentication -->
<http pattern="/api/**" create-session="stateless">
<intercept-url pattern="/**" access="ROLE_USER"/>
<http-basic/>
</http>
<!-- configure form-login authentication -->
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/ui/login" access="permitAll" />
<intercept-url pattern="/ui/logout" access="permitAll" />
<intercept-url pattern="/ui/loginfailed" access="permitAll" />
<intercept-url pattern="/**" access="ROLE_USER" />
<custom-filter ref="ajaxTimeoutRedirectFilter" after="EXCEPTION_TRANSLATION_FILTER" />
<form-login login-page="/ui/login" default-target-url="/" authentication-failure-url="/ui/loginfailed" />
<logout logout-success-url="/ui/logout" />
<session-management invalid-session-url="/ui/login"/>
</http>
My question is:
Is it possible to configure two different types of security (http-basic and form-login) for the same URL patterns using Spring Security? Is there a best practice for this type of scenario?
Thank you.
Why don't you just merge the two <http> elements like this:
<http pattern="/api/**" use-expressions="true">
<intercept-url pattern="/ui/login" access="permitAll" />
<intercept-url pattern="/ui/logout" access="permitAll" />
<intercept-url pattern="/ui/loginfailed" access="permitAll" />
<intercept-url pattern="/**" access="ROLE_USER" />
<http-basic/>
<custom-filter ref="ajaxTimeoutRedirectFilter" after="EXCEPTION_TRANSLATION_FILTER" />
<form-login login-page="/ui/login" default-target-url="/" authentication-failure-url="/ui/loginfailed" />
<logout logout-success-url="/ui/logout" />
<session-management invalid-session-url="/ui/login"/>
</http>
This would set up both a UsernamePasswordAuthenticationFilter and a BasicAuthenticationFilter in the same filter chain which could serve the ui client, and the external service as well.
Not possible out of the box to apply 2 different filter chain for a single URL pattern.
But it is a advisable to have unique URL patterns as UI and API, as you would have to apply a completely different filter chain in future.
For example the SecurityContextRepository hold the session information and is retrieved for each request. You don't want to apply the same for UI and API access through basic auth
Try to replace pattern="/" by pattern="/api/" in API config:
<http pattern="/api/**" create-session="stateless">
<intercept-url pattern="/api/**" access="ROLE_USER"/>
<http-basic/>
</http>
