CVE-2023-0862Public exploitNetwork attack vector

Authenticated code execution via traversed upload path

Published Feb 16, 2023 · Updated Mar 18, 2025

Path traversal in NetModule AG NRSW allows remote authenticated users to execute elevated commands through a malicious PHP upload. The /home/www-data/admin/include/sdkJobs.php handler appends the unvalidated scriptName field to UPLOAD_DIR and passes that path to move_uploaded_file. Administrative authentication is required; traversal into the web root permits PHP execution, and the same flaw also permits arbitrary file deletion.
