TITLE

plural NETGEAR Injection vulnerabilities in devices

Trust: 0.8

sources: JVNDB: JVNDB-2018-016408

DESCRIPTION

Certain NETGEAR devices are affected by command injection by an authenticated user. This affects D7800 before 1.0.1.34, R6400v2 before 1.0.2.34, R6700 before 1.0.1.30, R6900 before 1.0.1.30, R6900P before 1.0.0.62, R7000 before 1.0.9.12, R7000P before 1.0.0.62, R7500v2 before 1.0.3.26, R7800 before 1.0.2.42, R9000 before 1.0.3.10, WNDR4300v2 before 1.0.0.50, and WNDR4500v3 before 1.0.0.50. plural NETGEAR A device contains an injection vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR R6400, etc. are all products of NETGEAR. NETGEAR R6400 is a wireless router. NETGEAR R6700 is a wireless router. NETGEAR D7800 is a wireless modem. Injection vulnerabilities exist in many NETGEAR products. The vulnerability stems from the fact that the network system or product lacks the correct verification of the user input data during the operation process of the user inputting the construction command, data structure or record, and the special elements are not filtered or correctly filtered, resulting in the analysis or analysis of the system or product. The explanation is wrong. No detailed vulnerability details are currently provided. This affects D7800 prior to 1.0.1.34, R6400v2 prior to 1.0.2.34, R6700 prior to 1.0.1.30, R6900 prior to 1.0.1.30, R6900P prior to 1.0.0.62, R7000 prior to 1.0.9.12, R7000P prior to 1.0.0.62, R7500v2 prior to 1.0.3.26, R7800 prior to 1.0.2.42, R9000 prior to 1.0.3.10, WNDR4300v2 prior to 1.0.0.50, and WNDR4500v3 prior to 1.0.0.50
