CVE-2023-50225: Tp-link tl-wr902ac firmware stack-based buffer overflow vulnerability

Tp Link · Tl Wr902ac Firmware

TP-Link TL-WR902AC dm_fillObjByStr Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR902AC routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the libcmm.so module. 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-21819.
