CVE-2019-18992

Name of the Vulnerable Software and Affected Versions OpenWrt version 18.06.4

Description The issue allows for XSS via the Name fields in the /cgi-bin/luci/admin/network/firewall/rules API endpoint, specifically in the "Open ports on router", "New forward rule", and "New Source NAT" fields. This can be exploited on devices such as the TP-Link Archer C7.

Recommendations For OpenWrt version 18.06.4, avoid using the Name fields in the affected API endpoint until the issue is resolved. As a temporary workaround, consider restricting access to the /cgi-bin/luci/admin/network/firewall/rules API endpoint to minimize the risk of exploitation.
