Describe the bug spring cloud version : Greenwich.SR3 gateway version : 2.1.3.RELEASE

this is a Weird bug ,my project start ok and test success, it is run some day , one day it is have this bug .

this is my config

spring:
  cloud:
    gateway: 
      routes:
         - id: recharge-mobile
           uri: lb://recharge-mobile
           predicates:
             - Path=/recharge/mobile/**
           filters:
             - StripPrefix=1

[prefectchen]

how did you solve it

restart my project ,

[wangliangliang123456789]

Upgrade version to 2.2.5+

[zhangbo6248]

这是一个 Spring Cloud Gateway 新暴露的漏洞，参考： https://cloud.tencent.com/developer/article/1950978

[phxuecan]

how ?

[prefectchen]

Upgrade version to 2.2.5+ you also have this bug? I will try but what principle?

[prefectchen]

这是一个 Spring Cloud Gateway 新暴露的漏洞，参考： https://cloud.tencent.com/developer/article/1950978 感谢,我会发给领导看一下的 会试一下的

[wangliangliang123456789]

reference https://github.com/spring-cloud/spring-cloud-gateway/issues/1915

[prefectchen]

reference #1915 I also see #1915 ,But it's a little different from his problem I am sure my project can run success, and this path /recharge/mobile/order also can access, but someday it can not access ex: 2022.03.07 this path can access ,but 2022.03.08 it can not access . in this time , nothing change on this server

[tennisdd]

I'm having the same problem,system worked normally for four months before this problem occurred.

[prefectchen]

I'm having the same problem,system worked normally for four months before this problem occurred.

do you know what reason? I restart my project it is work ,but i do not know reason

[mikewoo]

@prefectchen did you solve this problem?

[prefectchen]

@prefectchen did you solve this problem?

no but I restart my project it is work success, or change my nacos gateway.yml config

[mm-soft-kp]

What‘s the nacos version

[spencergibb]

2.1.x is no longer supported and this is fixed in later versions, please upgrade

[prefectchen]

What‘s the nacos version

1.3.2

[prefectchen]

2.1.x is no longer supported and this is fixed in later versions, please upgrade I also want to upgarde but my leader ask me what reason , can you tell me ?

[prefectchen]

Hello, author. I read the source code and found that assertions are stored in a collection, but I didn't find out why there is this problem. Can you explain it briefly? I'd like to know the reason very much I hope you can guide me in your spare time

thanks

I also encountered the same problem. In the near future, there will be an array of service reports that cross the boundary in a few days. Have you solved it

@prefectchen Are there any problems with the upgraded version？which version did you upgrade to ？My problem is the same as yours

[prefectchen]

v2.2.5 you can try

me too , but my leader tell me restart gateway ,it is work . 

or you can change you nacos config (gateway.yml) ,the list always reload . be careful!!!!!

@prefectchen @yhtsnda 我也遇到了这个问题。排查了很久解决了。 check一下access.log有没有/actuator/gateway/routes/xxxx类似的请求。然后有/actuator/gateway/refresh的请求。 原因是楼上有人提到的安全漏洞。然后公司内部or外部有人在做安全渗透。 在第一个接口OPST的时候创建含有可执行脚本的路由请求。其中predicates数组为空。 在第二个接口refresh的时候会导致出现#1915的bug然后导致请求都500. 解决方案是/actuator/gateway/*的外部请求全部禁止掉。

在我的gateway日志中 确实找到了/actuator/gateway/routes请求 不过是get方式 而且没有其他参数 并没有 /actuator/gateway/refresh请求

/actuator/gateway/routes 这个路径爆出另一个错误

可以分析一下出问题之前短时间的access。然后结合你springcloud-gateway的版本看一下源码。

okk 我先把线上的程序弄好 然后去看下源码中的处理 感谢!!!

@prefectchen @yhtsnda 我也遇到了这个问题。排查了很久解决了。 check一下access.log有没有/actuator/gateway/routes/xxxx类似的请求。然后有/actuator/gateway/refresh的请求。 原因是楼上有人提到的安全漏洞。然后公司内部or外部有人在做安全渗透。 在第一个接口OPST的时候创建含有可执行脚本的路由请求。其中predicates数组为空。 在第二个接口refresh的时候会导致出现#1915的bug然后导致请求都500. 解决方案是/actuator/gateway/*的外部请求全部禁止掉。

我检查下，问题和你的很类似，感谢兄弟提示

I am also facing the same issue (Randomly) since last 2 days spring-boot version is : 2.0.4.RELEASE spring-cloud.version : Finchley.SR3

Issue is resolve by restarting gateway service, but face same problem after 1 day. So this is not reliable solution.

If anyone have permanent soultion, then please post here.

这是一个 Spring Cloud Gateway 新暴露的漏洞，参考： https://cloud.tencent.com/developer/article/1950978 感谢,我会发给领导看一下的 会试一下的

这个漏洞我们也出现了 只出现在线上 测试暂时没有出现过

As a solution I have upgrade my gateway service to : SpringBoot : 2.5.12 Spring cloud dependency to : 2020.0.5

I see on fix in this version as below, They have gracefully handle the condition.

private AsyncPredicate<ServerWebExchange> combinePredicates(RouteDefinition routeDefinition) {
    List<PredicateDefinition> predicates = routeDefinition.getPredicates();
    if (predicates == null || predicates.isEmpty()) {
        // this is a very rare case, but possible, just match all
        return AsyncPredicate.from(exchange -> true);
    }
    AsyncPredicate<ServerWebExchange> predicate = lookup(routeDefinition,
            predicates.get(0));

    for (PredicateDefinition andPredicate : predicates.subList(1,
            predicates.size())) {
        AsyncPredicate<ServerWebExchange> found = lookup(routeDefinition,
                andPredicate);
        predicate = predicate.and(found);
    }

    return predicate;
}
