Plain English Summary
AI-powered analysis for quick understanding
This vulnerability allows an attacker to access sensitive information, including the router's password and administrative password, in plain text through a flawed configuration download feature. If a user downloads this configuration, it can be stored in their browser's cache, making it accessible to anyone with access to that device.
Technical 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.
