Certain NETGEAR devices allow remote attackers to disable all authentication requirements by visiting genieDisableLanChanged.cgi. The attacker can then, for example, visit MNU_accessPassword_recovered.html to obtain a valid new admin password. This affects AC1450, D8500, DC112A, JNDR3000, LG2200D, R4500, R6200, R6200V2, R6250, R6300, R6300v2, R6400, R6700, R6900P, R6900, R7000P, R7000, R7100LG, R7300, R7900, R8000, R8300, R8500, WGR614v10, WN2500RPv2, WNDR3400v2, WNDR3700v3, WNDR4000, WNDR4500, WNDR4500v2, WNR1000, WNR1000v3, WNR3500L, and WNR3500L.

ZTE MW NR8000V2.4.4.03 and NR8000V2.4.4.04 are impacted by path traversal vulnerability. Due to path traversal,users can download any files.

An exploitable arbitrary memory read vulnerability exists in the KCodes NetUSB.ko kernel module which enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. A specially crafted index value can cause an invalid memory read, resulting in a denial of service or remote information disclosure. An unauthenticated attacker can send a crafted packet on the local network to trigger this vulnerability.

An exploitable information disclosure vulnerability exists in the KCodes NetUSB.ko kernel module that enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. An unauthenticated, remote attacker can craft and send a packet containing an opcode that will trigger the kernel module to return several addresses. One of which can be used to calculate the dynamic base address of the module for further exploitation.
