| 제목 | Netcore NR268 Router NR268-V1.7.121109.bin Insufficient Verification of Data Authenticity |
|---|
| 설명 | The NR268 firmware authenticity check is forgeable. `mtd_write` accepts an image when bytes `0x20..0x2f` equal `MD5(MD5(file[0x50:]) || hardcoded_constant)` and does not verify a vendor signature, public key, or device secret. An attacker who can reach the firmware upload route can modify a valid image, recompute the accepted header locally, and install the forged firmware. |
