TITLE

plural NETGEAR Injection vulnerabilities in devices

Trust: 0.8

sources: JVNDB: JVNDB-2018-016340

DESCRIPTION

Certain NETGEAR devices are affected by command injection by an unauthenticated attacker. This affects D6100 before 1.0.0.57, R6100 before 1.0.1.20, R7500v2 before 1.0.3.24, 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 R7500, etc. are all products of NETGEAR. NETGEAR R7500 is a wireless router. NETGEAR D6100 is a wireless modem. NETGEAR R6100 is a wireless router. 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 D6100 prior to 1.0.0.57, R6100 prior to 1.0.1.20, R7500v2 prior to 1.0.3.24, WNDR4300v2 prior to 1.0.0.50, and WNDR4500v3 prior to 1.0.0.50
