CRITICAL 9.1

DescriptionGitHub Advisory

InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. A critical Remote Code Execution (RCE) vulnerability exists in InvoicePlane 1.7.0 through a chained Local File Inclusion (LFI) and Log Poisoning attack. An authenticated administrator can execute arbitrary system commands on the server by manipulating the public_invoice_template setting to include poisoned log files containing PHP code. Version 1.7.1 patches the issue.

Executive ViewAI

Why It Matters

InvoicePlane installations (versions 1.7.0+) face critical remote code execution risk that could allow attackers to take complete control of systems and access sensitive financial data. Organizations using this application require immediate patching to prevent potential data breaches, system compromise, and operational disruption.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If patch deployment is delayed: implement Web Application Firewall (WAF) rules to block LFI payloads (monitor for directory traversal patterns like '../' and log file access attempts); restrict network access to InvoicePlane to authorized users only via firewall/VPN; disable file inclusion and dynamic code execution features if application functionality permits; enable enhanced logging and monitoring for file access and process execution on affected servers.

Attack Technique

Local File Inclusion HIGH

Local File Inclusion vulnerabilities occur when an application accepts user-controlled input to specify which file should be loaded or executed, typically through functions like PHP's `include()`, `require()`, or `fopen()`.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
