AI-suggested

Since the vulnerability arises from transmitting sensitive tokens via GET parameters, it is recommended to avoid passing authentication tokens in URLs. Instead, use more secure methods such as HTTP headers or POST parameters. Additionally, restrict access to logs that may contain sensitive tokens and consider rotating tokens if exposure is suspected. Monitor vendor advisories for any official fixes or updates.

Description

V2Board versions through 1.7.4 expose a sensitive server authentication token via a GET parameter in the UniProxyController. This token appears in URLs and can be logged in various places such as web server logs, browser history, and proxy/CDN logs. An attacker with access to these logs could extract the token and impersonate a proxy server node, potentially intercepting user traffic.
