CVE-2026-8272Public exploitNetwork attack vector

Authenticated command injection via shell-built file operations

Published May 11, 2026 · Updated May 11, 2026

OS command injection in D-Link DNS-320 2.06B01 allows remote authenticated users to execute commands through file operations. webfile_mgr.cgi reads file path and name parameters with cgiFormString() and inserts them through sprintf() into shell commands passed to system(). A valid session and high privileges are required, and successful injection grants command execution with the CGI process's device permissions.
