What is CVE-2023-35744?

The vulnerability resides in the DDP service of D-Link DAP-2622 routers, stemming from deficient validation of user-supplied data length prior to copying it to a fixed-length stack-based buffer. This oversight enables network-adjacent attackers to potentially execute arbitrary code on affected devices without the need for authentication. By exploiting this flaw, attackers can gain root-level access, thereby compromising the security and integrity of the affected installations.
