CVE-2023-35756 (GCVE-0-2023-35756)

Vulnerability from cvelistv5 – Published: 2024-05-03 01:58 – Updated: 2024-09-18 18:29

Summary

D-Link DAP-2622 DDP Set Date-Time Auth Password Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2622 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the DDP service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-20084.

Severity ?

8.8 (High)
