Missing Authorization
CVE CVE-2020-35948
CVSS 8.8 (High)
Publicly Published August 18, 2020
Last Updated January 22, 2024
Researcher Chloe Chamberland - Wordfence

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.
