CVE-2025-54253: Adobe Experience Manager Forms RCE Flaw

CVE-2025-54253 Overview

CVE-2025-54253 is a critical misconfiguration vulnerability affecting Adobe Experience Manager Forms versions 6.5.23 and earlier. This security flaw enables attackers to bypass security mechanisms and achieve arbitrary code execution on vulnerable systems. The vulnerability is particularly dangerous as it requires no user interaction and has a changed scope, meaning successful exploitation can impact resources beyond the vulnerable component's security scope.

Critical Impact

This vulnerability is actively being exploited in the wild and has been added to the CISA Known Exploited Vulnerabilities (KEV) catalog. Organizations running affected versions of Adobe Experience Manager Forms should treat remediation as an emergency priority.

Affected Products

• Adobe Experience Manager Forms versions 6.5.23 and earlier
• Adobe Experience Manager versions 6.5.23 and earlier

Technical Details for CVE-2025-54253

Vulnerability Analysis

This vulnerability stems from an Improper Authorization issue (CWE-863) within Adobe Experience Manager Forms. The misconfiguration allows unauthenticated attackers to bypass security controls that should restrict access to sensitive functionality. When exploited, attackers can execute arbitrary code on the target system with no prerequisites for authentication or user interaction.

Research from SLCyber indicates this vulnerability is related to Struts DevMode functionality that remains accessible in production deployments of Adobe Experience Manager Forms. This configuration oversight exposes powerful debugging capabilities that were never intended for production use, creating a direct path to code execution.

Root Cause

The root cause is an Improper Authorization (CWE-863) vulnerability where Adobe Experience Manager Forms fails to properly restrict access to sensitive administrative or debugging functionality. The misconfiguration allows the Struts DevMode feature—designed for development environments only—to be accessible in production deployments without proper authentication or access controls.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker with network access to a vulnerable Adobe Experience Manager Forms instance can exploit this misconfiguration remotely. The changed scope indicates that successful exploitation can affect resources and components beyond the initial vulnerable application, potentially compromising the underlying server infrastructure.

The exploitation path leverages the exposed Struts DevMode functionality to inject and execute arbitrary code. Since no special privileges or credentials are required, any network-connected attacker can potentially compromise vulnerable systems.

Detection Methods for CVE-2025-54253

Indicators of Compromise

• Unusual HTTP requests targeting Struts DevMode endpoints or debugging functionality
• Unexpected process execution originating from the Adobe Experience Manager Forms application
• Anomalous network connections from AEM Forms servers to external or internal resources
• Web server logs showing requests to development or debugging URLs that should not be accessible in production

Detection Strategies

• Monitor web application firewall (WAF) logs for requests containing Struts DevMode parameters or debugging-related paths
• Implement network intrusion detection rules to identify exploitation attempts targeting known AEM Forms attack patterns
• Deploy endpoint detection and response (EDR) solutions to identify post-exploitation behavior such as unauthorized code execution
• Review Adobe Experience Manager Forms configurations to verify DevMode and debugging features are disabled in production

Monitoring Recommendations

• Enable verbose logging on Adobe Experience Manager Forms instances to capture detailed request information
• Configure SIEM correlation rules to alert on suspicious activity patterns associated with AEM Forms exploitation
• Monitor for unauthorized file creation or modification within the AEM Forms installation directory
• Track outbound network connections from AEM Forms servers for potential data exfiltration or command-and-control communication

How to Mitigate CVE-2025-54253

Immediate Actions Required

• Upgrade Adobe Experience Manager Forms to the latest patched version as documented in Adobe Security Advisory APSB25-82
• Verify that Struts DevMode is explicitly disabled in all production AEM Forms configurations
• Restrict network access to AEM Forms administrative interfaces using firewall rules or network segmentation
• Review access logs for evidence of prior exploitation attempts and initiate incident response if suspicious activity is detected

Patch Information

Adobe has released a security update addressing this vulnerability as detailed in Adobe Security Advisory APSB25-82. Organizations should apply this update immediately, particularly given the vulnerability's inclusion in the CISA Known Exploited Vulnerabilities catalog, which mandates federal agencies to remediate within specified timeframes.

Workarounds

• Disable Struts DevMode functionality in the AEM Forms configuration files if patching cannot be performed immediately
• Implement web application firewall rules to block requests targeting known exploitation patterns
• Place vulnerable AEM Forms instances behind a VPN or restrict access to trusted IP addresses only
• Consider temporarily taking affected systems offline if they are internet-facing and cannot be patched or protected immediately

# Example: Verify Struts DevMode is disabled in configuration
# Check sling.properties or relevant AEM configuration files
grep -r "devMode" /opt/aem/crx-quickstart/conf/
# Ensure devMode=false or the setting is removed entirely
