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.

Description

CVE-2025-24813-Scanner is a Python-based vulnerability scanner that detects Apache Tomcat servers vulnerable to CVE-2025-24813, an arbitrary file upload vulnerability leading to remote code execution (RCE) via insecure PUT method handling and jsessionid exploitation.

Readme

## CVE-2025-24813 Scanner

A multi-threaded vulnerability scanner to detect Apache Tomcat servers vulnerable to CVE-2025-24813 (arbitrary file upload leading to RCE).

![License](https://img.shields.io/badge/license-MIT-green)

## Description

This scanner checks for Apache Tomcat servers vulnerable to CVE-2025-24813 by:
1. Attempting to upload a serialized Java object via HTTP PUT
2. Verifying if the uploaded file can be executed via jsessionid parameter

Features:
- Multi-threaded scanning (adjustable thread count)
- CSV input/output support
- Color-coded terminal output
- Detailed vulnerability verification
- Graceful interruption handling

## Installation

```bash
git clone https://github.com/yourusername/CVE-2025-24813-Scanner.git

```

### Full Options
```bash
python CVE-2025-24813-Scanner.py \
  -f targets.csv \          # Input CSV with host,ip,port columns
  -o vulnerable_hosts.csv \ # Save vulnerable targets
  -t 10 \                   # Use 10 threads
```

### Example Scenarios
