# AVideo: unauthenticated SSRF reads internal responses and cloud metadata credentials

AVideo's URL fetch helper accepts private, loopback and link-local destinations and skips TLS verification, and an unauthenticated login endpoint returns the fetched response body. An unauthenticated remote attacker can read internal HTTP and HTTPS responses, including cloud instance-metadata credentials, and reach internal TCP and FTP services.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the AVideo version: versions before `8.1.0` are affected, and the sources say `8.1.0` only partly fixes the issue.
- Check whether `Streamer::isURLAllowed` has an operator allowlist configured; the sources say an empty allowlist, the default, allows all sites.
- Check whether `objects/login.json.php` is reachable from the internet.

## Fix

- Upgrade AVideo past `8.1.0`, since the sources say that version only partly remediates the issue; the sources do not name a fully fixed version.
- Restrict outbound requests from the AVideo host to internal networks and cloud metadata addresses at the network layer.
- Set an explicit operator allowlist for `Streamer::isURLAllowed`.
- Block unauthenticated access to `objects/login.json.php` and `view/youtubeDl.json.php` until patched.

## From the sources

AVideo is a video-sharing Platform. Before the initial remediation attempt in 8.1.0, `url_get_contents` in `objects/functions.php` accepts caller-controlled destinations after only `FILTER_VALIDATE_URL` syntax validation, without rejecting private, loopback, or link-local addresses, and disables TLS peer verification. `Login::isLogged` reauthenticates using the attacker-settable `encoder_aVideoURL` cookie together with arbitrary nonempty `encoder_user` and `encoder_pass` cookies, and `Login::run` stores the raw fetched body in `result`. The unauthenticated `objects/login.json.php` endpoint returns that session object, enabling full-response exfiltration through a supplied `siteURL`; its `Streamer::isURLAllowed` gate allows all sites when the operator allowlist is empty, the default. An unauthenticated remote attacker can read internal HTTP and HTTPS responses, including cloud instance-metadata credentials, and reach internal TCP services. A further pre-authentication FTP variant in `view/youtubeDl.json.php` routes an ftp `videoURL` into `FTPDownloader`; `parseFtpUrl` in `objects/FTPDownloader.php` accepts its host and port for `ftp_connect`. This also enables requests to internal FTP services. Untrusted self-signed HTTPS certificates are accepted, and no account or operator interaction is required. Version 8.1.0 contains an initial remediation attempt that removes raw-response reflection and adds destination checks, but private-network exemptions and login TLS-verification defaults leave complete remediation of the described internal-network and TLS variants unresolved.
