CWE-918

Allowed

Server-Side Request Forgery (SSRF)

Abstraction: Base · Status: Incomplete

API response cwe.mitre.org

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

Summary
Shopware: SSRF in Media External-Link Endpoint Bypasses IP Validation
Details

Summary

The /api/_action/media/external-link endpoint allows authenticated admin users to make server-side HTTP HEAD requests to arbitrary internal IP addresses. While the parallel uploadFromURL flow validates target IPs against private/reserved ranges via FileUrlValidator, the linkURL flow only performs a URL format check (regex for http:// or https:// prefix), allowing SSRF to internal network services and cloud metadata endpoints.

Details

The vulnerability is an inconsistency between two URL-handling flows in MediaUploadService.

Vulnerable path (external-link):

MediaUploadV2Controller::externalLink() at src/Core/Content/Media/Api/MediaUploadV2Controller.php:66 takes a user-supplied url parameter and passes it to MediaUploadService::linkURL() at src/Core/Content/Media/Upload/MediaUploadService.php:134.

linkURL() calls getContentSizeFromValidExternalUrl($url) at line 159, which only validates via validateExternalUrl():

// src/Core/Content/Media/Upload/MediaUploadService.php:207-212
public static function validateExternalUrl(string $url): void
{
    if (!preg_match('/^https?:\/\/.+/', $url)) {
        throw MediaException::invalidUrl($url);
    }
}

Then makes a server-side HEAD request with no IP filtering:

// src/Core/Content/Media/Upload/MediaUploadService.php:292-300
private function getContentSizeFromValidExternalUrl(string $url): int
{
    $this->validateExternalUrl($url);

    $headers = $this->httpClient->request('HEAD', $url)->getHeaders();
    if (!\array_key_exists('content-length', $headers)) {
        throw MediaException::fileNotFound($url);
    }

    return (int) $headers['content-length'][0];
}

Protected path (upload_by_url):

In contrast, uploadFromURL uses FileFetcher::fetchFromURL() which calls FileUrlValidator::isValid():

// src/Core/Content/Media/File/FileFetcher.php:64
if ($this->enableUrlValidation && !$this->fileUrlValidator->isValid($url)) {
    throw MediaException::illegalUrl($url);
}

FileUrlValidator::isValid() resolves the hostname via gethostbyname() and validates the IP against private and reserved ranges using filter_var() with FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE. This protection is entirely absent from the linkURL flow.

Impact

An authenticated admin user can:

  1. Probe cloud metadata services — HEAD requests to 169.254.169.254 reveal whether cloud metadata endpoints exist and leak content-length values
  2. Scan internal networks — Differentiate open/closed/filtered ports on internal hosts (10.x, 172.16.x, 192.168.x) based on response timing and error types
  3. Leak internal service information — The fileSize field stored in the database reflects the content-length header from internal services
  4. Redirect-based escalation — Symfony HttpClient follows redirects by default (max_redirects=20), allowing an attacker-controlled external server to redirect the HEAD request to arbitrary internal destinations

Impact is limited to information disclosure via HEAD requests. The admin authentication requirement (PR:H) reduces exploitability, but in multi-tenant or compromised-credential scenarios this allows network reconnaissance from the server's perspective.

Recommended Fix

Apply FileUrlValidator to the linkURL flow, consistent with the uploadFromURL flow. In MediaUploadService:

// src/Core/Content/Media/Upload/MediaUploadService.php

// Add constructor dependency:
private readonly FileUrlValidatorInterface $fileUrlValidator;

// In getContentSizeFromValidExternalUrl(), add IP validation:
private function getContentSizeFromValidExternalUrl(string $url): int
{
    $this->validateExternalUrl($url);

    if (!$this->fileUrlValidator->isValid($url)) {
        throw MediaException::illegalUrl($url);
    }

    $headers = $this->httpClient->request('HEAD', $url)->getHeaders();
    if (!\array_key_exists('content-length', $headers)) {
        throw MediaException::fileNotFound($url);
    }

    return (int) $headers['content-length'][0];
}

Additionally, consider setting max_redirects: 0 on the HttpClient request to prevent redirect-based SSRF bypasses.

Vulnerability from github – Published: 2025-07-16 18:32 – Updated: 2025-07-16 18:32
VLAI
Details

A vulnerability in the web-based management interface of Cisco Unified Intelligence Center could allow an unauthenticated, remote attacker to conduct a server-side request forgery (SSRF) attack through an affected device.

This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to send arbitrary network requests that are sourced from the affected device.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
