Description

NETGEAR RAX30 cmsCli_authenticate Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within a shared library used by the telnetd service, which listens on TCP port 23 by default. 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-19918.

Affected configurations

• netgear rax30 firmware (< 1.0.11.96 2 hotfix)
