环境信息

Springboot2.0 + Spring Security

代码追踪

我们可以找到org.springframework.security.web.firewall.StrictHttpFirewall

/**
 * 

 * Determines if semicolon is allowed in the URL (i.e. matrix variables). The default
 * is to disable this behavior because it is a common way of attempting to perform
 * Reflected File Download Attacks.
 * It is also the source of many exploits which bypass URL based security.
 * 
 * 
For example, the following CVEs are a subset of the issues related
 * to ambiguities in the Servlet Specification on how to treat semicolons that
 * led to CVEs:
 * 
 * 

 *     
cve-2016-5007
 *     
cve-2016-9879
 *     
cve-2018-1199
 * 
 *
 * 

 * If you are wanting to allow semicolons, please reconsider as it is a very common
 * source of security bypasses. A few common reasons users want semicolons and
 * alternatives are listed below:
 * 
 * 

 * 
Including the JSESSIONID in the path - You should not include session id (or
 * any sensitive information) in a URL as it can lead to leaking. Instead use Cookies.
 * 
 * 
Matrix Variables - Users wanting to leverage Matrix Variables should consider
 * using HTTP parameters instead.
 * 
 * 
 *
 * @param allowSemicolon should semicolons be allowed in the URL. Default is false
 */
public void setAllowSemicolon(boolean allowSemicolon) {
    if (allowSemicolon) {
        urlBlacklistsRemoveAll(FORBIDDEN_SEMICOLON);
    } else {
        urlBlacklistsAddAll(FORBIDDEN_SEMICOLON);
    }
}

这里提到了，如果您想要分号，请重新考虑，因为它是安全绕过的一个非常常见的来源。 下面列出了用户需要分号和替代品的一些常见原因：
在路径中包含JSESSIONID - 您不应在URL中包含会话ID（或任何敏感信息），因为它可能导致泄漏。 而是使用Cookies。

解决方案

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public HttpFirewall allowUrlSemicolonHttpFirewall() {
        StrictHttpFirewall firewall = new StrictHttpFirewall();
        firewall.setAllowSemicolon(true);
        return firewall;
    }
}

放开了该安全限制，就不会遇到该报错了，不适合对于安全性要求非常高的应用。
