Authenticated code execution via unrestricted file upload
Published Sep 16, 2022 · Updated Aug 3, 2024
Unrestricted file upload in EspoCRM 7.1.8 allows remote authenticated users to execute arbitrary code by uploading a malicious server-side file. The published record does not identify a function or endpoint; it states that upload handling accepts malicious files with any extension and leaves them executable by the server. A low-privilege authenticated account is required, and successful execution compromises the EspoCRM server.
