CVE-2022-4232Network attack vector

Arbitrary file upload via cmd request argument

Published Nov 30, 2022 · Updated Aug 3, 2024

Unrestricted file upload in SourceCodester Event Registration System 1.0 allows remote authenticated users to upload arbitrary files. The published record identifies the cmd request argument as the trigger but does not disclose the endpoint, handler, or validation operation that accepts the file. The CNA assessment requires high privileges, and the documented consequence is file placement rather than established code execution.
