CVE-2025-45479Public exploitNetwork attack vector

Remote code execution via writable NFS mount

Published Jul 7, 2025 · Updated Jul 8, 2025

Code injection in EduCoder Challenges 1.0 allows remote attackers to execute arbitrary code through a writable container-mounted export. A privileged challenge container fails to block NFS mounting, so an attacker can mount the server's /platform/eva export read-write and replace or delete hosted files. Access to a running experimental challenge container and reachability of the internal NFS service are required; successful file replacement grants server-side execution and data access.
