The request was rejected because the URL contained a potentially malicious String "%2e"

org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String "%2e"

org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String “%3B”

org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String “//”

类似这些报错,意思时请求URL中有非法字符“;”原因是SpringSecurity的防火墙中默认将分号,双斜线等特殊字符屏蔽掉了。

解决办法

  • 1.去掉url中的分号,双斜线等特殊字符(推荐)

  • 2.自定义防火墙规则,放行特殊字符
    SecurityConfig配置类中增加HttpFirewall的Bean

 @Bean
    public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
        StrictHttpFirewall firewall = new StrictHttpFirewall();
        firewall.setAllowUrlEncodedDoubleSlash(true);
        firewall.setAllowBackSlash(true);
        firewall.setAllowSemicolon(true);
        firewall.setAllowUrlEncodedPercent(true);
        firewall.setAllowUrlEncodedSlash(true);
        firewall.setAllowUrlEncodedPeriod(true);
        return firewall;
    }

同时在Websecurity中配置此bean

    @Override
    public void configure(WebSecurity web) throws Exception {
        super.configure(web);
        web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
    }

注:
setAllowSemicolon(true)为放行分号(;或者%3b或者%3B),

setAllowUrlEncodedSlash(true) 放行斜杠(%2f或者%2F)

setAllowBackSlash(boolean) 放行反斜杠(\或者%5c或者%5B)

setAllowUrlEncodedPercent(boolean) 放行百分号(URL编码后为%25)

setAllowUrlEncodedPeriod(boolean) 放行英文句号.(%2e或者%2E)
