An exploitable firmware downgrade vulnerability was discovered on the Netgear WPN824EXT WiFi Range Extender. An attacker can conduct a MITM attack to replace the user-uploaded firmware image with an original old firmware image. This affects Firmware 1.1.1_1.1.9 and earlier.

Weakness

The product does not validate or incorrectly validates the integrity check values or “checksums” of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
