Cacti <= 1.2.26 (import.php) Remote Code Execution Vulnerability

• Affected Versions:

Version 1.2.26 and prior versions.

• Vulnerability Description:

The vulnerability is located within the import_package() function defined into the /lib/import.php script. This function blindly trusts the filename and file content provided within the uploaded XML data, and writes such files into the Cacti base path (or even outside, since Path Traversal sequences are not filtered). This can be exploited to write or overwrite arbitrary files on the web server, leading to execution of arbitrary PHP code or other security impacts.

Successful exploitation of this vulnerability requires an user account having the “Import Templates” permission.

• Solution:

Upgrade to version 1.2.27 or later.

[17/01/2024] – Vendor notified through GitHub
