Executive & SecOps Summary
SECOPS ASSESSMENTAdobe Experience Manager (AEM) versions 6.5.23 and earlier (specifically with Forms module and Struts DevMode enabled)
Unauthenticated remote attackers can bypass security controls and execute arbitrary system commands or code with system privileges
Apply the official Adobe APSB25-82 security patch immediately and disable Struts DevMode in production environments
Affected Products & Version Scope
Remediation & Live Workaround Commands
PATCH & WORKAROUND1. Official Patch & Version Upgrade Commands
Apply the official cumulative fix pack or service pack recommended in Adobe Security Bulletin APSB25-82. Below is an example of deploying the patch using the AEM Package Manager API.
# Upload and install the latest AEM security patch via Package Manager API
curl -u 'admin:YOUR_ADMIN_PASSWORD' \
-F file=@'AEM-6.5.24-Cumulative-Fix-Pack.zip' \
-F force=true \
-F install=true \
http://localhost:4502/crx/packmgr/service.jsp2. Temporary Workaround & Hardening Configuration
If immediate patching is not feasible, restrict access to the vulnerable endpoints and block Struts debugging parameters at the WAF or reverse proxy level.
# Nginx configuration to block Struts DevMode and debugging parameters
server {
listen 80;
server_name your-aem-domain.com;
# Block common Struts DevMode exploitation parameters
if ($query_string ~* 'debug=') {
return 403;
}
if ($query_string ~* 'expression=') {
return 403;
}
location / {
proxy_pass http://aem-author:4502;
}
}3. Log Audit & IoC Verification Commands
Verify if Struts DevMode is enabled in your running environment and inspect the access logs for potential exploitation attempts.
# 1. Check if Struts DevMode is enabled in the running Java process arguments
ps -ef | grep -i 'aem' | grep -E 'devMode|struts.devMode'
# 2. Scan AEM request logs for suspicious debug parameters or OGNL injection attempts
grep -Ei '(\?|&)debug=|ognl|java.lang.Runtime' /mnt/crx/author/crx-quickstart/logs/request.logBlock 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
CVE-2025-54253 is a critical misconfiguration vulnerability in Adobe Experience Manager (AEM) Forms. The root cause lies in the improper exposure or activation of Apache Struts Developer Mode (DevMode) within the AEM Forms environment. This misconfiguration allows unauthenticated remote attackers to bypass built-in security mechanisms and execute arbitrary code on the host system. It has been assigned a CVSS 3.1 score of 10.0 (Critical).
2. Exploitation Mechanics & Attack Scenario
An attacker can exploit this vulnerability by sending crafted HTTP requests containing malicious parameters to the vulnerable AEM Forms endpoints. Because Struts DevMode is active or accessible, the application processes debugging parameters (such as OGNL expressions or parameter manipulation commands) without proper authentication. This enables the attacker to achieve remote code execution (RCE) without any user interaction. Due to active wild exploitation, CISA has added this vulnerability to its Known Exploited Vulnerabilities (KEV) catalog.
3. Infrastructure & Business Impact
Successful exploitation of this vulnerability grants the attacker full control over the AEM server. This can lead to complete compromise of sensitive document workflows, theft of database credentials, lateral movement within the corporate network, deployment of ransomware, and unauthorized access to personally identifiable information (PII) managed by AEM Forms.
Official Vendor Advisories & References
Adobe Experience Manager versions 6.5.23 and earlier are affected by a Misconfiguration vulnerability that could result in arbitrary code execution. An attacker could leverage this vulnerability to bypass security mechanisms and execute code. Exploitation of this issue does not require user interaction and scope is changed.
