An exploitable firmware modification vulnerability exists in certain Netgear products. The data integrity of the uploaded firmware image is ensured with a fixed checksum number. Therefore, an attacker can conduct a MITM attack to modify the user-uploaded firmware image and bypass the checksum verification. This affects WNR612v2 Wireless Routers 1.0.0.3 and previous versions, DGN1000v3 Modem Router 1.0.0.22 and previous versions, D6100 WiFi DSL Modem Routers 1.0.0.63 and previous versions, WNR1000v2 Wireless Routers 1.1.2.60 and previous versions, XAVN2001v2 Wireless-N Extenders 0.4.0.7 and previous versions, WNR2200 Wireless Routers 1.0.1.102 and previous versions, WNR2500 Wireless Routers 1.0.0.34 and previous versions, R8900 Smart WiFi Routers 1.0.3.6 and previous versions, and R9000 Smart WiFi Routers 1.0.3.6 and previous versions.
