Description

Shenzhen Tenda F3 Wireless Router firmware V12.01.01.55_multi contains a sensitive information exposure vulnerability in the configuration download functionality. The configuration download response includes the router password and administrative password in plaintext. The endpoint also omits appropriate Cache-Control directives, which can allow the response to be stored in client-side caches and recovered by other local users or processes with access to cached browser data.
