Name of the Vulnerable Software and Affected Versions NETGEAR RAX30 (affected versions not specified)

Description This issue allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
