代码追踪
我们可以找到org.springframework.security.web.firewall.StrictHttpFirewall
/**
* <p>
* 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
* <a href="https://www.owasp.org/index.php/Reflected_File_Download">Reflected File Download Attacks</a>.
* It is also the source of many exploits which bypass URL based security.
* </p>
* <p>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:
* </p>
* <ul>
* <li><a href="https://pivotal.io/security/cve-2016-5007">cve-2016-5007</a></li>
* <li><a href="https://pivotal.io/security/cve-2016-9879">cve-2016-9879</a></li>
* <li><a href="https://pivotal.io/security/cve-2018-1199">cve-2018-1199</a></li>
* </ul>
*
* <p>
* 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:
* </p>
* <ul>
* <li>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.
* </li>
* <li>Matrix Variables - Users wanting to leverage Matrix Variables should consider
* using HTTP parameters instead.
* </li>
* </ul>
*
* @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。
