我有一个Spring Boot Web应用程序(Spring Boot版本2.0.3.RELEASE),并且在Apache Tomcat 8.5.5服务器中运行。
使用Google Chrome实施的最新安全策略(自80.0开始淘汰),要求它应用新的SameSite
属性以更安全的方式进行跨站点Cookie的访问, CSRF。由于我没有做任何相关的事情,并且Chrome为第一方Cookie设置了默认值SameSite=Lax
,因此我的一个第三方服务集成失败,原因是chrome在以下情况下限制了跨站点Cookie的访问SameSite=Lax
,并且如果第三方响应来自POST
请求(由于该过程完成了通过POST
请求将第三方服务重定向到我们的站点 )。在该位置,Tomcat无法找到该会话,因此它在URL的末尾附加了一个新的JSESSIONID
(带有一个新的会话,并且先前的会话已被终止)。因此,Spring拒绝了该URL,因为它包含由新的JSESSIONID
附加项引入的分号。
因此,我需要更改JSESSIONID
cookie属性(SameSite=None; Secure
)并通过多种方法进行尝试,包括WebFilters。我在Stackoverflow中看到了相同的问题和答案,并尝试了其中的大多数问题,但最终在任何地方。
有人可以提出一个解决方案来更改Spring Boot中的标头吗?
答案 0 :(得分:1)
我之前也处于同样的情况。由于SameSite
类中没有类似javax.servlet.http.Cookie
的类,因此无法添加。
第1部分:因此,我写了一个过滤器,该过滤器仅拦截所需的第三方请求。
public class CustomFilter implements Filter {
private static final String THIRD_PARTY_URI = "/third/party/uri";
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
if(THIRD_PARTY_URI.equals(request.getRequestURI())) {
chain.doFilter(request, new CustomHttpServletResponseWrapper(response));
} else {
chain.doFilter(request, response);
}
}
enter code here
// ... init destroy methods here
}
第2部分: Cookie是作为Set-Cookie
响应标头发送的。因此,此CustomHttpServletResponseWrapper
会覆盖addCookie
方法并检查是否为必需的cookie(JSESSIONID
),而不是将其添加到cookie中,而是直接添加到响应标头Set-Cookie
中具有SameSite=None
属性。
public class CustomHttpServletResponseWrapper extends HttpServletResponseWrapper {
public CustomHttpServletResponseWrapper(HttpServletResponse response) {
super(response);
}
@Override
public void addCookie(Cookie cookie) {
if ("JSESSIONID".equals(cookie.getName())) {
super.addHeader("Set-Cookie", getCookieValue(cookie));
} else {
super.addCookie(cookie);
}
}
private String getCookieValue(Cookie cookie) {
StringBuilder builder = new StringBuilder();
builder.append(cookie.getName()).append('=').append(cookie.getValue());
builder.append(";Path=").append(cookie.getPath());
if (cookie.isHttpOnly()) {
builder.append(";HttpOnly");
}
if (cookie.getSecure()) {
builder.append(";Secure");
}
// here you can append other attributes like domain / max-age etc.
builder.append(";SameSite=None");
return builder.toString();
}
}

我能够为此提出自己的解决方案。
我有两种在Spring Boot上运行的应用程序,它们具有不同的Spring安全配置,并且需要不同的解决方案来解决此问题。
情况1:无用户身份验证
在这里,您可能已经在应用程序中为第三方响应创建了一个端点。在使用控制器方法访问httpSession之前,您是安全的。如果您以不同的控制器方法访问会话,则向临时主机发送临时重定向请求,如下所示。
@Controller
public class ThirdPartyResponseController{
@RequestMapping(value=3rd_party_response_URL, method=RequestMethod.POST)
public void thirdPartyresponse(HttpServletRequest request, HttpServletResponse httpServletResponse){
// your logic
// and you can set any data as an session attribute which you want to access over the 2nd controller
request.getSession().setAttribute(<data>)
try {
httpServletResponse.sendRedirect(<redirect_URL>);
} catch (IOException e) {
// handle error
}
}
@RequestMapping(value=redirect_URL, method=RequestMethod.GET)
public String thirdPartyresponse(HttpServletRequest request, HttpServletResponse httpServletResponse, Model model, RedirectAttributes redirectAttributes, HttpSession session){
// your logic
return <to_view>;
}
}
仍然,您需要在安全配置中允许3rd_party_response_url。
情况2:用户需要通过身份验证/登录
在通过HttpSecurity或WebSecurity配置了大多数安全规则的Spring Web应用程序中,请检查此解决方案。
我已经测试了解决方案的示例安全配置:
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.
......
..antMatchers(<3rd_party_response_URL>).permitAll();
.....
..csrf().ignoringAntMatchers(<3rd_party_response_URL>);
}
}
我要在此配置中重点强调的一点是,您应该允许Spring Security和CSRF保护(如果已启用)中的第三方响应URL。
然后,我们需要通过扩展GenericFilterBean类(Filter类对我不起作用)并将SameSite
属性设置为JSESSIONID
cookie来创建HttpServletRequest过滤器拦截每个HttpServletRequest
并设置响应头。
import org.apache.commons.lang3.StringUtils;
import org.springframework.http.HttpHeaders;
import org.springframework.web.filter.GenericFilterBean;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Arrays;
import java.util.List;
public class SessionCookieFilter extends GenericFilterBean {
private final List<String> PATHS_TO_IGNORE_SETTING_SAMESITE = Arrays.asList("resources", <add other paths you want to exclude>);
private final String SESSION_COOKIE_NAME = "JSESSIONID";
private final String SAME_SITE_ATTRIBUTE_VALUES = ";HttpOnly;Secure;SameSite=None";
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse resp = (HttpServletResponse) response;
String requestUrl = req.getRequestURL().toString();
boolean isResourceRequest = requestUrl != null ? StringUtils.isNoneBlank(PATHS_TO_IGNORE_SETTING_SAMESITE.stream().filter(s -> requestUrl.contains(s)).findFirst().orElse(null)) : null;
if (!isResourceRequest) {
Cookie[] cookies = ((HttpServletRequest) request).getCookies();
if (cookies != null && cookies.length > 0) {
List<Cookie> cookieList = Arrays.asList(cookies);
Cookie sessionCookie = cookieList.stream().filter(cookie -> SESSION_COOKIE_NAME.equals(cookie.getName())).findFirst().orElse(null);
if (sessionCookie != null) {
resp.setHeader(HttpHeaders.SET_COOKIE, sessionCookie.getName() + "=" + sessionCookie.getValue() + SAME_SITE_ATTRIBUTE_VALUES);
}
}
}
chain.doFilter(request, response);
}
}
然后通过以下方式将此过滤器添加到Spring Security过滤器链中:
@Override
protected void configure(HttpSecurity http) throws Exception {
http.
....
.addFilterAfter(new SessionCookieFilter(), BasicAuthenticationFilter.class);
}
此SameSite
cookie属性将不支持某些old browser versions,在这种情况下,请检查浏览器并避免在不兼容的客户端中设置SameSite
。
private static final String _I_PHONE_IOS_12 = "iPhone OS 12_";
private static final String _I_PAD_IOS_12 = "iPad; CPU OS 12_";
private static final String _MAC_OS_10_14 = " OS X 10_14_";
private static final String _VERSION = "Version/";
private static final String _SAFARI = "Safari";
private static final String _EMBED_SAFARI = "(KHTML, like Gecko)";
private static final String _CHROME = "Chrome/";
private static final String _CHROMIUM = "Chromium/";
private static final String _UC_BROWSER = "UCBrowser/";
private static final String _ANDROID = "Android";
/*

public static boolean isSameSiteInCompatibleClient(HttpServletRequest request) {
String userAgent = request.getHeader("user-agent");
if (StringUtils.isNotBlank(userAgent)) {
boolean isIos12 = isIos12(userAgent), isMacOs1014 = isMacOs1014(userAgent), isChromeChromium51To66 = isChromeChromium51To66(userAgent), isUcBrowser = isUcBrowser(userAgent);
//TODO : Added for testing purpose. remove before Prod release.

LOG.info("*********************************************************************************");
return isIos12 || isMacOs1014 || isChromeChromium51To66 || isUcBrowser;
}
return false;
}
private static boolean isIos12(String userAgent) {
return StringUtils.contains(userAgent, _I_PHONE_IOS_12) || StringUtils.contains(userAgent, _I_PAD_IOS_12);
}
private static boolean isMacOs1014(String userAgent) {
return StringUtils.contains(userAgent, _MAC_OS_10_14)
&& ((StringUtils.contains(userAgent, _VERSION) && StringUtils.contains(userAgent, _SAFARI)) //Safari on MacOS 10.14
|| StringUtils.contains(userAgent, _EMBED_SAFARI)); // Embedded browser on MacOS 10.14
}
private static boolean isChromeChromium51To66(String userAgent) {
boolean isChrome = StringUtils.contains(userAgent, _CHROME), isChromium = StringUtils.contains(userAgent, _CHROMIUM);
if (isChrome || isChromium) {
int version = isChrome ? Integer.valueOf(StringUtils.substringAfter(userAgent, _CHROME).substring(0, 2))
: Integer.valueOf(StringUtils.substringAfter(userAgent, _CHROMIUM).substring(0, 2));
return ((version >= 51) && (version <= 66)); //Chrome or Chromium V51-66
}
return false;
}
private static boolean isUcBrowser(String userAgent) {
if (StringUtils.contains(userAgent, _UC_BROWSER) && StringUtils.contains(userAgent, _ANDROID)) {
String[] version = StringUtils.splitByWholeSeparator(StringUtils.substringAfter(userAgent, _UC_BROWSER).substring(0, 7), ".");
int major = Integer.valueOf(version[0]), minor = Integer.valueOf(version[1]), build = Integer.valueOf(version[2]);
return ((major != 0) && ((major < 12) || (major == 12 && (minor < 13)) || (major == 12 && minor == 13 && (build < 2)))); //UC browser below v12.13.2 in android
}
return false;
}
像下面这样在SessionCookieFilter中添加以上检查,
if (!isResourceRequest && !UserAgentUtils.isSameSiteInCompatibleClient(req)) {
此过滤器在本地主机环境中不起作用,因为它需要安全(HTTPS)连接来设置Secure
cookie属性。
