Local file disclosure via unchecked query path
Published Aug 3, 2026 · Updated Aug 3, 2026
Path traversal in OpenWrt LuCI allows remote attackers to read local files through the unauthenticated bmx7-info CGI endpoint. The script treats the raw QUERY_STRING as a path under BMX7_DIR, ignores the failed check_path result, and passes traversal segments to print_query. Network access to the CGI endpoint is sufficient, and disclosure is limited to files readable by the CGI process in revisions before commit 5890760a454dad2cb00389dba2cdc5e779e0ffdd.
