An exploitable firmware modification vulnerability was discovered on the Netgear XWN5001 Powerline 500 WiFi Access Point

An exploitable firmware modification vulnerability was discovered on the Netgear XWN5001 Powerline 500 WiFi Access Point. An attacker can conduct a MITM (Man-in-the-Middle) attack to modify the user-uploaded firmware image and bypass the CRC check, allowing attackers to execute arbitrary code or cause a Denial of Service (DoS). This affects v0.4.1.1 and earlier.
