CVE-2022-35239Network attack vector

Authenticated PHP code execution via file upload

Published Aug 16, 2022 · Updated Aug 3, 2024

Improper file-upload validation in CONTEC SolarView Compact 7.23 and earlier allows remote authenticated users to execute PHP code. The image file management page accepts a specially crafted PHP file without sufficient verification and permits its execution by the embedded web server. Access to an authenticated session and the upload page is required; successful exploitation grants arbitrary PHP execution on the appliance.
