CVE-2020-14965Network attack vector

Stored script execution via unfiltered access-control names

Published Jun 23, 2020 · Updated Aug 4, 2024

Stored cross-site scripting in TP-Link TL-WR740N v4 and TL-WR740ND v4 allows remote attackers to alter access-control pages via crafted names. The targets_lists_name and hosts_lists_name fields accept injected HTML that is preserved and rendered in target and station page contexts. Direct submission requires admin-panel access, but a crafted cross-site request can make an authenticated administrator store the payload, enabling script execution when an affected page is viewed.
