Description

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, SuiteCRM contains an authenticated arbitrary file upload vulnerability in the Configurator module. An authenticated administrator can bypass intended file type restrictions when uploading PDF font files, allowing arbitrary files with attacker‑controlled filenames to be written to the server. Although the upload directory is not directly web‑accessible by default, this behavior breaks security boundaries and may enable further attacks when combined with other vulnerabilities or in certain deployment configurations. Versions 7.15.1 and 8.9.3 patch the issue.

Affected products

SuiteCRM: before 7.15.1; from 8.0.0 before 8.9.3 — fixed in 7.15.1, 8.9.3

How to fix

Upgrade to a fixed version: SuiteCRM 7.15.1, 8.9.3. Check the vendor advisory for mitigations.
