PHP 7.3.x < 7.3.31 Arbitrary File Write

medium Nessus Plugin ID 154650

Language:

Synopsis

The version PHP running on the remote web server is affected by a vulnerability.

Description

The version of PHP installed on the remote host is 7.3.x prior to 7.3.31. It is, therefore, affected by a vulnerability as referenced in the version 7.3.31 advisory. In the Microsoft Windows environment, ZipArchive::extractTo may be tricked into writing a file outside target directory when extracting a ZIP file, thus potentially causing files to be created or overwritten, subject to OS permissions.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 7.3.31 or later.
