CVE-2023-2453

Local file Inclusion (LFI) in Forum Infusion via Directory Traversal

Description

There is insufficient sanitization of tainted file names that are directly concatenated with a path that is subsequently passed to a ‘require_once’ statement. This allows arbitrary files with the ‘.php’ extension for which the absolute path is known to be included and executed. There are no known means in PHPFusion through which an attacker can upload and target a ‘.php’ file payload.

Remediation

Workaround:

  • Disabling the “Forum” Infusion through the admin panel removes the endpoint through which this vulnerability is exploited, and so prevents the issue. If the “Forum” Infusion cannot be disabled, technologies such as a web application firewall may help to mitigate exploitation attempts.
