VAR-202110-1760
Vulnerability from variot - Updated: 2023-12-18 13:51This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6260 1.1.0.78_1.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the setupwizard.cgi page. When parsing the SOAP_LOGIN_TOKEN environment variable, the process does not properly validate 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-14107. Zero Day Initiative To this vulnerability ZDI-CAN-14107 Was numbering.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. NETGEAR R6260 is a router from Netgear. A hardware device that connects two or more networks and acts as a gateway between the networks
