TITLE

D-Link DIR-850L Command injection vulnerability in device firmware

Trust: 0.8

sources: JVNDB: JVNDB-2017-008110

DESCRIPTION

The DHCP client on D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices allows unauthenticated remote code execution as root because /etc/services/INET/inet_ipv4.php mishandles shell metacharacters, affecting generated files such as WAN-1-udhcpc.sh. D-Link DIR-850L The device firmware contains a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. D-LinkDIR-850LREV.A and REV.B are both D-Link wireless router products. A security vulnerability exists in the DHCP client on the REV.B device using D-LinkDIR-850LREV.A and FW208WWb02 and previous versions of firmware using FW114WWb07_h2ab_beta1 and previous firmware. The vulnerability is due to the /etc/services/INET/inet_ipv4.php file. Handle shell metacharacters correctly. A remote attacker could exploit the vulnerability to execute code with root privileges
