CyberRota Analysis
AI-GeneratedThe Kerberos Agent prior to version 3.6.26 is vulnerable due to improper handling of HTTP redirects, which can result in the exposure of sensitive Hub credentials through custom request headers during cross-host redirects. This vulnerability could allow an attacker to intercept and misuse the Hub private key, leading to unauthorized access to the video management system. Organizations using this software should prioritize updating to version 3.6.26 or later to mitigate the risk of credential leakage.

Original NVD Description
Kerberos Agent is an open source video (surveillance) management agent. Prior to version 3.6.26, the Kerberos Hub upload path sends the agent's Hub credentials in the custom `X-Kerberos-Hub-PrivateKey` and `X-Kerberos-Hub-PublicKey` request headers to the operator-configured Hub URL (`config.HubURI`). The HTTP client used (`&http.Client{}` in `UploadKerberosHub`) is constructed without a `CheckRedirect` policy, so it follows HTTP redirects automatically. Go's `net/http` strips only sensitive headers (`Authorization`, `Cookie`, `WWW-Authenticate`) on a cross-host redirect; it does not strip custom headers such as `X-Kerberos-Hub-PrivateKey`. As a result, if the configured `HubURI` returns a cross-host 30x redirect, the Hub private key is forwarded verbatim to the redirect target, disclosing the credential to an unintended third party. Version 3.6.26 fixes the issue by implementing the `CheckRedirect` strip plus a cross-host regression test is provided to the maintainer through the advisory's private temporary fork.
