CVE-2022-46432

An exploitable firmware modification vulnerability was discovered on TP-Link TL-WR743ND V1. 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 v3.12.20 and earlier.
