Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Requires timely remediation of identified flaws, such as patching the unrestricted file upload vulnerability in InvoicePlane's upload_file method.

SI-10 Information Input Validation good match

prevent

Mandates validation of all information inputs, including uploaded files, to reject dangerous types and content that enable remote code execution.

SI-3 Malicious Code Protection good match

preventdetect

Deploys malicious code protection mechanisms to scan and block uploaded files containing executable code leading to RCE.

NVD Description

InvoicePlane (all versions tested as of December 2024) v.1.6.11 and before contains a remote code execution vulnerability in the upload_file method of the Upload controller.

Deeper analysisAI

CVE-2024-56975 is a remote code execution vulnerability in InvoicePlane versions 1.6.11 and prior, with all versions tested as of December 2024 confirmed affected. The flaw resides in the upload_file method of the Upload controller, classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), highlighting its critical severity due to network accessibility, low attack complexity, and lack of prerequisites.

Unauthenticated attackers with network access to an affected InvoicePlane instance can exploit the vulnerability remotely without user interaction. Successful exploitation enables arbitrary code execution on the server, potentially granting full control over the system and leading to high-impact compromise of confidentiality, integrity, and availability.

Mitigation involves applying fixes from the referenced GitHub pull requests: https://github.com/InvoicePlane/InvoicePlane/pull/1127 and https://github.com/InvoicePlane/InvoicePlane/pull/1166, which address the issue in the Upload controller.
