| 标题 | Netcore NR268 Router NR268-V1.7.121109.bin Insufficient Verification of Data Authenticity |
|---|
| 描述 | The NR268 parameter restore path accepts any uploaded archive that begins with the three-byte marker .XG. The restore chain then strips those three bytes and untars the remainder without a signature, MAC, or full-file integrity check./router/parame_put_file.cgi validates only the first three bytes of the upload against .XG. After the prefix matches, the handler strips exactly those bytes and unpacks the remainder as a tar.gz archive. There is no signature, HMAC, or whole-file digest over the configuration payload. |
