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.
AnalysisAI
V2Board through version 1.7.4 exposes sensitive server authentication tokens via GET parameters in the UniProxy API endpoint, causing tokens to be recorded in web server access logs, browser history, HTTP Referer headers, and intermediary proxies. An attacker who obtains access to any log source can extract the token and impersonate a proxy server node, potentially intercepting all user traffic passing through that node.
