what is the use of auto-config=true in spring security - java

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."

Disabling Headers on Specific URLs

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>

Spring security access with multiple roles

I want to define access for some pages for user who has one of following roles (ROLE1 or ROLE2)
I'm trying to configure this in my spring security xml file as following:
<security:http entry-point-ref="restAuthenticationEntryPoint" access-decision-manager-ref="accessDecisionManager" xmlns="http://www.springframework.org/schema/security" use-expressions="true">
<!-- skipped configuration -->
<security:intercept-url pattern="/rest/api/myUrl*" access="hasRole('ROLE1') or hasRole('ROLE2')" />
<!-- skipped configuration -->
</security:http>
I've tried various ways like:
access="hasRole('ROLE1, ROLE2')"
access="hasRole('ROLE1', 'ROLE2')"
access="hasAnyRole('[ROLE1', 'ROLE2]')"
etc
but nothing seems to be working.
I'm keep getting exception
java.lang.IllegalArgumentException: Unsupported configuration attributes:
or
java.lang.IllegalArgumentException: Failed to parse expression 'hasAnyRole(['ROLE1', 'ROLE2'])'
how should it be configured?
Thanks
How try with , separate. See doc here and here.
<security:intercept-url pattern="/rest/api/myUrl*" access="ROLE1,ROLE2"/>
OR
hasAnyRole('ROLE1','ROLE2')
The problem was that I configured custom access-decision-manager-ref="accessDecisionManager"
and didn't pass one of the voters.
Solved by adding org.springframework.security.web.access.expression.WebExpressionVoter to accessDecisionManager bean.

Spring security for overlap URL range

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')"/>
...

Spring Security, trailing slashes, and dots in URLs

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')"/>

give access with spring security in xml file for one user

I was using waffle and spring security 3.2 to set access to jsf2 pages.
I used this example
Everything works fine, but I am curious, if posible to set access to page via xml file for one user???
Something like that:
<sec:intercept-url pattern="/**" access="PRINCIPAL='tom'" />
I couldn't find answer in internet
Thanks
Yes it is possible if you use SpEL expressions:
<sec:http use-expressions="true">
....
<sec:intercept-url pattern="/**" access="principal.name=='tom'" />
....
</sec:http>
Using #Maksym answer I found my solution (I think in some cases both can be right) :
<sec:http use-expressions="true">
....
<sec:intercept-url pattern="/**" access="authentication.name=='tom'" />
....
</sec:http>
