Weaknesses (CWE)

CWE-598Use of HTTP Request With Sensitive Query String

Description

Sensitive server_token exposed via GET parameter in V2Board thru 1.7.4. In app/Http/Controllers/Server/UniProxyController.php, the server authentication token is accepted via GET parameter transmission. The token appears in URLs such as /api/v1/server/UniProxy/user?token=SECRET, causing it to be recorded in web server access logs, browser history, HTTP Referer headers, and proxy/CDN logs. An attacker who gains access to any log source can extract the token and impersonate a proxy server node, potentially intercepting all user traffic.
