Defending Apache Struts: Codenotary Guardian's Swift RCE Protection

Understanding the RCE Vulnerability in Apache Struts

Remote code execution vulnerabilities in Apache Struts typically arise due to insufficient input validation, deserialization flaws, or improper use of object-graph navigation language (OGNL). For instance, the infamous Struts 2 vulnerability (CVE-2017-5638) was caused by improper handling of untrusted user input, allowing attackers to execute arbitrary system commands via crafted HTTP requests.

Exploitation Example:

1. The attacker sends a malicious payload in the Content-Type header of an HTTP request.
2. The vulnerable Apache Struts server fails to properly sanitize the input and executes it as a system command.
3. This grants the attacker full control over the server, allowing data exfiltration, malware installation, and lateral movement across the net

How Codenotary Guardian Detects and Patches RCE Vulnerabilities in Real-Time

Traditional security solutions rely on manual patching, log analysis, or intrusion detection systems to catch such attacks after they occur. Codenotary Guardian (https://guardian.codenotary.com) , however, provides a proactive and automated approach that detects and mitigates vulnerabilities like Apache Struts RCE in real time without requiring sysadmin intervention.

Key Capabilities of Guardian:

• Continuous Runtime Monitoring: Guardian actively scans all running applications and detects anomalies in execution behavior.
• AI-Powered Threat Detection: Uses behavior-based analysis to detect unauthorized execution attempts that indicate an RCE attack.
• Automated Remediation: If a vulnerability is detected, Guardian can immediately block execution, prevent payload delivery, and deploy security patches in real-time.
• Immutable Software Bill of Materials (SBOM): Ensures only trusted and verified components run in the system, eliminating risks from unverified updates or rogue code execution.

Why Guardian Stands Out

Unlike conventional security tools that require manual intervention, Guardian provides zero-day protection by stopping exploits at runtime. If a new RCE vulnerability is discovered in Apache Struts, Guardian would automatically detect abnormal execution patterns and block malicious payloads before they execute.

The Apache Struts RCE vulnerabilities underscore the need for robust, automated security solutions. With Codenotary Guardian, organizations can achieve real-time protection without waiting for manual patches or relying on outdated intrusion detection methods. By leveraging AI-powered insights, Guardian ensures that even the most sophisticated threats are neutralized before they can compromise critical systems.
