Detailsinfo

A vulnerability classified as problematic has been found in Netgear D7800, EX2700, EX6100v2, EX6150v2, EX6200v2, EX6400, EX7300, R7500v2, R7800, R8900, R9000, WN2000RPTv3, WN3000RPv2, WN3000RPv3, WN3100RPv2, WNDR4300v2, WNDR4500v3, WNR2000v5, XR450 and XR500 (Wireless LAN Software). This affects an unknown functionality. The manipulation with an unknown input leads to a cross site scripting vulnerability (Stored). CWE is classifying the issue as CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on integrity. The summary by CVE is:

Certain NETGEAR devices are affected by stored XSS. This affects D7800 before 1.0.1.47, EX2700 before 1.0.1.48, EX6100v2 before 1.0.1.76, EX6150v2 before 1.0.1.76, EX6200v2 before 1.0.1.72, EX6400 before 1.0.2.136, EX7300 before 1.0.2.136, R7500v2 before 1.0.3.38, R7800 before 1.0.2.52, R8900 before 1.0.4.12, R9000 before 1.0.4.12, WN2000RPTv3 before 1.0.1.32, WN3000RPv2 before 1.0.0.68, WN3000RPv3 before 1.0.2.70, WN3100RPv2 before 1.0.0.66, WNDR4300v2 before 1.0.0.58, WNDR4500v3 before 1.0.0.58, WNR2000v5 before 1.0.0.66, XR450 before 2.3.2.32, and XR500 before 2.3.2.32.
