CVE-2023-31474Public exploitNetwork attack vector

Directory listing via unchecked opkg package name

Published May 9, 2023 · Updated Jan 29, 2025

Parameter injection in GL.iNet router firmware 3.215 and earlier allows remote authenticated users to list arbitrary directories. The software installation endpoint forwards a wildcard-bearing name parameter to opkg without rejecting path patterns, then returns opkg errors containing the expanded filenames. Access requires an administrative session token, and the demonstrated consequence is disclosure of directory entries rather than file contents.
