CWE-613 Insufficient Session Expiration

Description

Insufficient Session Expiration

Reference: https://cwe.mitre.org/data/definitions/613.html

OWASP Category: A07:2021 – Identification and Authentication Failures

---

Vulnerable Pattern

❌ Example 1: Vulnerable Pattern

// VULNERABLE: No session timeout configured
@Configuration
public class SecurityConfig {
    // No session management configured
}

Why it's vulnerable: This pattern is vulnerable to Insufficient Session Expiration

---

Deterministic Fix

✅ Secure Implementation: Secure Implementation

// SECURE: Configure session timeout and management
@Configuration
@EnableWebSecurity
public class SecurityConfig {
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.sessionManagement(session -> session
            .sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
            .maximumSessions(1)
            .expiredUrl("/session-expired")
        );
        return http.build();
    }
}
// In application.properties:
// server.servlet.session.timeout=30m

Why it's secure: Implements proper protection against Insufficient Session Expiration

---

Detection Pattern

Look for these patterns in your codebase:

# Find session configuration
grep -rn "sessionManagement\\|session.timeout" --include="*.java" --include="*.properties"

---

Remediation Steps

1. Set appropriate session timeout (15-30 minutes for sensitive apps)

2. Invalidate session on logout

3. Limit concurrent sessions

4. Re-authenticate for sensitive operations

---

Key Imports

import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

import org.springframework.security.config.http.SessionCreationPolicy;

---

Verification

After remediation:

• Run SAST scanner to confirm vulnerability is resolved

• Review all instances of the vulnerable pattern

• Add unit tests that verify the secure implementation

• Check for similar patterns in related code
