From 2.0.0 until 2.5.0, the self-upgrade mechanism validates a downloaded binary only with a same-origin digest obtained from the same upgrade mirror. A compromised mirror or network attacker able to alter both responses can supply a malicious executable and matching digest. An operator-triggered upgrade is required, and the application installs and runs the attacker-controlled code in the Nginx UI process context on the next upgrade. This issue is fixed in version 2.5.0.</p> <p>Nginx UI is a web user interface for the Nginx web server.

Both the binary and the digest come from the same origin, and there is NO cryptographic signature / public-key verification. The downloaded binary then replaces the running executable (`selfupdate.CommitBinary`) and the process restarts, so the binary runs as the nginx-ui user (typically root).</p> <p>Because integrity rests only on a digest fetched from the same place as the binary, anyone who controls that download path can substitute a malicious binary plus a matching digest and obtain code execution as root on the next upgrade. Additionally, the `github_proxy` setting accepts `http://` URLs, so the binary+digest can be fetched over cleartext.</p> <p>## Affected code - `internal/version/url.go GetUrl(path)` = `&lt;github_proxy or cloud.nginxui.com&gt;/&lt;path&gt;` — used for BOTH the binary and the digest. - `internal/upgrader/upgrade.go DownloadLatestRelease`: digest URL and binary URL are both wrapped with `GetUrl()`, fetched, and checked with `digestFileContent == DigestSHA512(tarName)`.
