Openwrt before v21.02.3 and Openwrt v22.03.0-rc6 were discovered to contain two skip loops in the function header_value(). This vulnerability allows attackers to access sensitive information via a crafted HTTP request.

OpenWrt 21.02.1 allows XSS via the NAT Rules Name screen.

OpenWrt 21.02.1 allows XSS via the Traffic Rules Name screen.

OpenWrt 21.02.1 allows XSS via the Port Forwards Add Name screen.

There is missing input validation of host names displayed in OpenWrt before 19.07.8. The Connection Status page of the luci web-interface allows XSS, which can be used to gain full control over the affected system via ICMP.

A stored cross-site scripting (XSS) vulnerability was discovered in the Web Interface for OpenWRT LuCI version 19.07 which allows attackers to inject arbitrary Javascript in the OpenWRT Hostname via the Hostname Change operation.

The Web Interface for OpenWRT LuCI version 19.07 and lower has been discovered to have a cross-site scripting vulnerability which can lead to attackers carrying out arbitrary code execution.

applications/luci-app-ddns/luasrc/model/cbi/ddns/detail.lua in the DDNS package for OpenWrt 19.07 allows remote authenticated users to inject arbitrary commands via POST requests.

In OpenWrt 19.07.x before 19.07.7, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set. This affects the netifd and odhcp6c packages.

LuCI in OpenWrt 18.06.0 through 18.06.4 allows stored XSS via a crafted SSID.
