Title

AVideo has Unauthenticated SSRF via plugin/Live/test.php

Summary

WWBN AVideo is an open source video platform. In versions up to and including 26.0, an unauthenticated server-side request forgery vulnerability in `plugin/Live/test.php` allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints. Commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3 contains a patch.

Vulnerability from github – Published: 2026-03-20 20:57 – Updated: 2026-03-25 20:31

Summary

AVideo has Unauthenticated SSRF via plugin/Live/test.php

Details

Summary

An unauthenticated server-side request forgery vulnerability in plugin/Live/test.php allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints.

Details

The endpoint accepts $_REQUEST['statsURL'] and only checks that it starts with http:

$statsURL = $_REQUEST['statsURL'];
if (empty($statsURL) || $statsURL == "php://input" || !preg_match("/^http/", $statsURL)) {
    exit;
}

It then calls:

$result = url_get_contents($statsURL, 2);

Inside the same file, url_get_contents() performs a real outbound request with file_get_contents() when allow_url_fopen is enabled:

$tmp = file_get_contents($url, false, $context);
_log('file_get_contents:: '.htmlentities($tmp));

There is:

no authentication check
no allowlist of trusted stats URLs
no SSRF-safe URL validation
reflected response/error output

Validated on source:

test.php

PoC

Target used during validation:

http://127.0.0.1:80

Probe a closed localhost port:

curl -s \
  'http://127.0.0.1:80/plugin/Live/test.php?statsURL=http://127.0.0.1:1/'

Observed response excerpt:

Starting try to get URL http://127.0.0.1:1/
url_get_contents start timeout=2
Warning: file_get_contents(http://127.0.0.1:1/): Failed to open stream: Connection refused
file_get_contents fail return an empty content
FAIL

Probe the local web service itself:

curl -s \
  'http://127.0.0.1:80/plugin/Live/test.php?statsURL=http://127.0.0.1:80/'

This returns upstream connection details from the server-side request and confirms the endpoint can target local/internal HTTP services.

Impact

This is an unauthenticated SSRF vulnerability affecting any deployment that exposes plugin/Live/test.php.

An attacker can:

probe localhost and internal network services
distinguish open and closed ports
target cloud metadata endpoints if reachable
retrieve reflected content from internal HTTP services when the upstream responds with a body

The server and the internal network reachable from it are impacted. No unauthenticated code execution was validated from this issue on the tested environment.

remediation

The safest fix is to remove plugin/Live/test.php from production deployments.

If it must remain:

require admin authentication
only allow requests to explicitly configured Live stats URLs
block localhost, RFC1918, link-local, and metadata IP ranges
stop reflecting fetched bodies and raw upstream errors to the client

Minimal hardening example:

require_once dirname(__FILE__) . '/../../videos/configuration.php';

if (!User::isAdmin()) {
    http_response_code(403);
    exit('Forbidden');
}

$statsURL = $_REQUEST['statsURL'] ?? '';
if (empty($statsURL) || !isSSRFSafeURL($statsURL)) {
    exit('Unsafe URL');
}

Remove `wget` Fallback Entirely

The wget fallback provides no unique value over file_get_contents + curl and introduces shell exposure. Remove lines 94–119 of test.php.

If wget must remain, escape the argument:

// BEFORE (vulnerable)
$cmd = "wget --tries=1 {$url} -O {$filename} --no-check-certificate";

// AFTER (safe)
$cmd = "wget --tries=1 " . escapeshellarg($url) . " -O " . escapeshellarg($filename) . " --no-check-certificate";

Defense in Depth

Move the file behind the admin panel URL prefix (Apache/Nginx deny rule for public access)
Add isSSRFSafeURL() check (already exists in objects/functions.php) before any fetch
Block outbound connections from the web process to RFC1918 addresses at the firewall/egress level

Severity

9.3 (Critical)

Probe a closed localhost port:\n\n```bash\ncurl -s \\\n  \u0027http://127.0.0.1:80/plugin/Live/test.php?statsURL=http://127.0.0.1:1/\u0027\n```\n\nObserved response excerpt:\n\n```text\nStarting try to get URL http://127.0.0.1:1/\nurl_get_contents start timeout=2\nWarning: file_get_contents(http://127.0.0.1:1/): Failed to open stream: Connection refused\nfile_get_contents fail return an empty content\nFAIL\n```\n\n2. Probe the local web service itself:\n\n```bash\ncurl -s \\\n  \u0027http://127.0.0.1:80/plugin/Live/test.php?statsURL=http://127.0.0.1:80/\u0027\n```\n\nThis returns upstream connection details from the server-side request and confirms the endpoint can target local/internal HTTP services.\n\n### Impact\nThis is an unauthenticated SSRF vulnerability affecting any deployment that exposes `plugin/Live/test.php`.\n\nAn attacker can:\n\n- probe localhost and internal network services\n- distinguish open and closed ports\n- target cloud metadata endpoints if reachable\n- retrieve reflected content from internal HTTP services when the upstream responds with a body\n\nThe server and the internal network reachable from it are impacted. No unauthenticated code execution was validated from this issue on the tested environment.\n\n### remediation\nThe safest fix is to remove `plugin/Live/test.php` from production deployments.\n\nIf it must remain:\n\n- require admin authentication\n- only allow requests to explicitly configured Live stats URLs\n- block localhost, RFC1918, link-local, and metadata IP ranges\n- stop reflecting fetched bodies and raw upstream errors to the client\n\nMinimal hardening example:\n\n```php\nrequire_once dirname(__FILE__) . \u0027/../../videos/configuration.php\u0027;\n\nif (!User::isAdmin()) {\n    http_response_code(403);\n    exit(\u0027Forbidden\u0027);\n}\n\n$statsURL = $_REQUEST[\u0027statsURL\u0027] ?? \u0027\u0027;\nif (empty($statsURL) || !isSSRFSafeURL($statsURL)) {\n    exit(\u0027Unsafe URL\u0027);\n}\n```\n\n### Remove `wget` Fallback Entirely\n\nThe `wget` fallback provides no unique value over `file_get_contents` + `curl` and introduces shell exposure. Remove lines 94\u2013119 of `test.php`.\n\n### If wget must remain, escape the argument:\n\n```php\n// BEFORE (vulnerable)\n$cmd = \"wget --tries=1 {$url} -O {$filename} --no-check-certificate\";\n\n// AFTER (safe)\n$cmd = \"wget --tries=1 \" . escapeshellarg($url) . \" -O \" . escapeshellarg($filename) . \" --no-check-certificate\";\n```\n\n### Defense in Depth\n\n1. Move the file behind the admin panel URL prefix (Apache/Nginx deny rule for public access)\n2. Add `isSSRFSafeURL()` check (already exists in `objects/functions.php`) before any fetch\n3. Block outbound connections from the web process to RFC1918 addresses at the firewall/egress level",
