Adobe Commerce and Magento Open Source Remote Code Execution (RCE) Vulnerability Advisory (CVE-2022-24086)
Executive & SecOps Summary
SECOPS ASSESSMENTAdobe Commerce and Magento Open Source versions 2.4.3-p1 (and earlier) and 2.3.7-p2 (and earlier)
Unauthenticated attackers can exploit improper input validation during the checkout process to execute arbitrary code (RCE) without user interaction, potentially leading to full system compromise
Immediately apply the official Adobe security patches (APSB22-12) and update Web Application Firewall (WAF) rules
Affected Products & Version Scope
Remediation & Live Workaround Commands
PATCH & WORKAROUND1. Official Patch & Version Upgrade Commands
Apply the official security patches recommended in Adobe Security Bulletin APSB22-12 using Composer.
# Install Magento Quality Patches tool
composer require magento/quality-patches
# Apply the specific patch for CVE-2022-24086 (MDVA-43395 or MDVA-43443)
./vendor/bin/magento-patches apply MDVA-43395
# Upgrade and clear cache to apply changes
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush2. Temporary Workaround & Hardening Configuration
If immediate patching is not feasible, configure your web server or WAF to block requests containing suspicious template directives or PHP execution patterns in the checkout payload.
# Nginx configuration snippet to block common template injection patterns
server {
location / {
# Block requests containing double curly braces or PHP execution functions in the body
if ($request_body ~* '(?:\{\{|system\(|exec\(|passthru\(|shell_exec\(|proc_open\(|popen\()') {
return 403;
}
try_files $uri $uri/ /index.php$is_args$args;
}
}3. Log Audit & IoC Verification Commands
Use the following commands to inspect web server access logs and database records for potential indicators of compromise (IoCs).
# Scan web server access logs for template injection attempts targeting checkout endpoints
grep -Ei 'checkout|payment' /var/log/nginx/access.log | grep -E '\{\{|system|exec|eval'
# Query the Magento database to identify suspicious payloads in order address fields
mysql -u -p[password] [db_name] -e "SELECT entity_id, firstname, lastname, street, email FROM sales_order_address WHERE firstname LIKE '%{{%' OR lastname LIKE '%{{%' OR street LIKE '%{{%';"Block Exploits Instantly with Managed Virtual Patching Rules
Can't patch production immediately? Deploy managed WAF rules at the edge to intercept RCE, SQLi, and deserialization payloads before they hit your origin server.
Technical Root Cause & Exploitation Mechanics
1. Vulnerability Overview & Root Cause
This vulnerability (CVE-2022-24086) is a critical improper input validation flaw (CWE-20) residing within the checkout process of Adobe Commerce and Magento Open Source. The root cause lies in the application's failure to properly sanitize and validate user-supplied input before passing it to internal processing components or template rendering engines during checkout operations. This allows malicious input to be interpreted and executed as code on the server side.
2. Exploitation Mechanics & Attack Scenario
An unauthenticated attacker can initiate a checkout transaction without requiring any prior privileges or user interaction. By injecting malicious payloads containing PHP code or template directives (e.g., {{markup}}) into checkout fields such as billing/shipping addresses or customer names, the attacker targets the order processing pipeline. When the application dynamically processes or renders these fields (such as during transactional email generation), the injected payload is executed under the privileges of the web server process, granting the attacker arbitrary command execution.
3. Infrastructure & Business Impact
With a CVSS score of 9.8, this vulnerability is classified as Critical and is actively exploited in the wild, as confirmed by its inclusion in the CISA KEV catalog. Successful exploitation allows attackers to establish persistent backdoors (e.g., web shells), exfiltrate sensitive customer data and payment card information (violating PCI-DSS compliance), or deploy ransomware, posing severe financial and reputational risks to the business.
Official Vendor Advisories & References
Adobe Commerce versions 2.4.3-p1 (and earlier) and 2.3.7-p2 (and earlier) are affected by an improper input validation vulnerability during the checkout process. Exploitation of this issue does not require user interaction and could result in arbitrary code execution.
