CVE-2025-2396Network attack vector

Authenticated code execution via unrestricted web-shell upload

Published Mar 17, 2025 · Updated Mar 17, 2025

Arbitrary file upload in e-Excellence U-Office Force before 28.0 allows remote authenticated users to execute code via a web shell. TWCERT/CC does not identify the affected upload handler or disclose how it fails to reject executable server-side content before storing it in a web-accessible location. Regular user privileges are sufficient; successful exploitation installs a backdoor that runs arbitrary code on the application server.
