TITLE

plural NETGEAR On the device OS Command injection vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2018-016400

DESCRIPTION

Certain NETGEAR devices are affected by command injection by an authenticated user. This affects D7800 before 1.0.1.34, R7500v2 before 1.0.3.26, R7800 before 1.0.2.42, R8900 before 1.0.3.10, R9000 before 1.0.3.10, WNDR4300v2 before 1.0.0.54, and WNDR4500v3 before 1.0.0.54. plural NETGEAR On the device OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR D7800, etc. are all products of NETGEAR. NETGEAR D7800 is a wireless modem. NETGEAR R7500 is a wireless router. NETGEAR WNDR4300 is a wireless router. The vulnerability stems from the process of constructing operating system executable commands from external input data. The network system or product does not properly filter the special characters and commands. The attacker can use this vulnerability to execute Illegal operating system command. This affects D7800 prior to 1.0.1.34, R7500v2 prior to 1.0.3.26, R7800 prior to 1.0.2.42, R8900 prior to 1.0.3.10, R9000 prior to 1.0.3.10, WNDR4300v2 prior to 1.0.0.54, and WNDR4500v3 prior to 1.0.0.54
