CVE-2024-46373Network attack vector

Code execution via unrestricted backend file upload

Published Sep 18, 2024 · Updated Sep 19, 2024

Unrestricted file upload in DedeCMS 5.7.115 allows remote attackers to execute arbitrary code through the web backend. The public disclosure does not identify the backend handler or explain which filename, type, or content validation permits a dangerous file. Exploitation is network-reachable and unauthenticated in CISA's assessment, but requires user interaction; the resulting code runs in server context.
