CVE-2025-57644: Accela Automation Platform RCE Vulnerability

CVE-2025-57644 Overview

Accela Automation Platform 22.2.3.0.230103 contains multiple critical vulnerabilities in the Test Script feature. An authenticated administrative user can execute arbitrary Java code on the server, resulting in remote code execution. In addition, improper input validation allows for arbitrary file write and server-side request forgery (SSRF), enabling interaction with internal or external systems. Successful exploitation can lead to full server compromise, unauthorized access to sensitive data, and further network exploitation.

Critical Impact

This vulnerability chain allows authenticated administrators to achieve full server compromise through remote code execution, arbitrary file write, and SSRF, potentially enabling lateral movement across internal networks.

Technical Details for CVE-2025-57644

Vulnerability Analysis

The vulnerability resides within the Test Script feature of Accela Automation Platform, a government software solution widely used for civic engagement and regulatory processes. The core issue stems from improper input validation (CWE-20) that allows authenticated administrative users to inject and execute arbitrary Java code on the server.

The vulnerability chain presents three distinct attack vectors within the same feature: remote code execution through arbitrary Java code execution, arbitrary file write capabilities that can be leveraged to deploy malicious payloads or modify critical system files, and server-side request forgery (SSRF) that enables attackers to interact with internal network resources or external systems. The changed scope indicator means successful exploitation can impact resources beyond the vulnerable component's security authority.

Root Cause

The root cause is improper input validation (CWE-20) in the Test Script functionality. The platform fails to adequately sanitize or restrict user-supplied input before processing it within the Java runtime environment. This allows administrative users to craft malicious payloads that bypass intended security boundaries and execute with elevated server-side privileges.

Attack Vector

The attack is network-accessible and requires authenticated administrative access to the Accela Automation Platform. While the prerequisite of administrative credentials raises the barrier to exploitation, the vulnerability still poses significant risk in scenarios involving compromised admin accounts, insider threats, or privilege escalation from lower-privileged accounts.

The exploitation flow involves an attacker authenticating as an administrator, navigating to the Test Script feature, and injecting malicious Java code or crafting requests that trigger the arbitrary file write or SSRF vulnerabilities. The SSRF component is particularly dangerous as it can be used to probe internal network resources, access metadata services in cloud environments, or pivot to other systems.

Detection Methods for CVE-2025-57644

Indicators of Compromise

• Unexpected Java process execution or child processes spawned by the Accela application server
• Unusual outbound network connections from the Accela server to internal or external IP addresses
• Modifications to files outside of expected application directories
• Administrative access from unusual IP addresses or at unusual times
• HTTP requests to internal network resources or cloud metadata endpoints originating from the server

Detection Strategies

• Monitor and alert on administrative authentication events, particularly from new or unusual source IPs
• Implement application-layer logging for the Test Script feature to capture all execution attempts
• Deploy network detection rules to identify SSRF patterns such as requests to internal IP ranges or cloud metadata services (e.g., 169.254.169.254)
• Use endpoint detection and response (EDR) solutions to monitor for anomalous process execution on the Accela server

Monitoring Recommendations

• Enable verbose logging for the Accela Automation Platform administrative console
• Configure SIEM alerts for repeated or suspicious Test Script feature usage
• Monitor file integrity on the Accela server for unauthorized modifications
• Track outbound network connections from the application server for anomalous destinations

How to Mitigate CVE-2025-57644

Immediate Actions Required

• Review and audit all administrative accounts with access to the Accela Automation Platform
• Restrict access to the Test Script feature to only essential personnel
• Implement network segmentation to limit the blast radius of potential SSRF exploitation
• Enable enhanced logging and monitoring for the affected system
• Contact Accela support to inquire about available patches or firmware updates

Patch Information

Organizations should consult the official Accela website for patch availability and guidance on upgrading to a secured version of the Automation Platform. Review the detailed vulnerability disclosure for additional context and remediation recommendations.

Workarounds

• Disable or restrict access to the Test Script feature until a patch is available
• Implement network-level controls to block outbound requests from the Accela server to unauthorized destinations
• Apply strict IP allowlisting for administrative access to the platform
• Consider deploying a web application firewall (WAF) with rules to detect and block code injection attempts

# Example: Restrict administrative access via IP allowlist (nginx)
location /admin {
    allow 10.0.0.0/8;
    deny all;
}
