Vulnerability from variot
The Comcast firmware on Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421746-170221a-CMCST) devices allows Network Processor (NP) Linux users to obtain root access to the Application Processor (AP) Linux system via shell metacharacters in commands. Cisco DPC3939 Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Cisco DPC3939 is a wireless voice gateway product from Cisco. A security vulnerability exists in the Cisco DPC3939 firmware. Allows an attacker to execute arbitrary commands on an Application Processor (ARM) Linux instance on the gateway. Comcast is a set of firmware developed by Comcast Corporation of the United States that runs in devices such as gateways and modems. An attacker could exploit this vulnerability to gain root access by using shell metacharacters in commands
