AI risk analysis

Summary: The flaw allows a malicious PHP file to be executed with web-server privileges, enabling remote code execution.
Exploitability: Exploitation is moderately hard as it requires placing a malicious PHP file in a writable directory, but once done, it can be easily triggered by rendering a public invoice.
Blast radius: If exploited, the impact could be severe, as it allows full control over the web server running InvoicePlane.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 1.7.2-rc-1 or later.

NVD description

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2-rc-1, InvoicePlane builds its permitted template list by scanning a PHP template directory that can be written through an administrator-controlled file-write capability. A malicious PHP file placed in the directory is automatically trusted by Mdl_templates and can be selected as public_invoice_template. When a public invoice is rendered, the guest View controller includes the trusted file and executes it with web-server privileges. This issue is fixed in version 1.7.2-rc-1.
