Details

Vulnerability Description

Attacker-controlled data is used in a code execution context without undergoing escaping or validation. This indicates a remote code execution vulnerability.

• Severity: critical

• CVSS Score: 9 (critical)

• CWE: CWE-77: Remote Code Execution

Attack Payloads

[
1. "'; System.exit(0); //"
2. "'|| true -- |' + 'system('cat /etc/passwd')' --"
3. "'x() { echo -e '\x6a\x68\x65\x8b\x04\x89\xe3\x57\x48\x89\xe6\xb0\x0b\x89\xf3\xb3\x01\x89\xc1\xb2\x0c\xcd\x80'; } x();"
]

Testcases

Below are three test cases designed to validate the effectiveness of the mitigation strategies implemented against the attack payloads listed. These test cases simulate real-world scenarios where inputs might be manipulated to exploit vulnerabilities.

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

public class SearchControllerTest {

    private SearchController searchController = new SearchController();

    @Test
    public void testValidInput() {
        assertEquals("Expected valid result", searchController.doGetSearch("validInput"), "Valid input should not cause any issues.");
    }

    @Test
    public void testAttackPayload1() {
        Exception exception = assertThrows(IllegalArgumentException.class, () -> {
            searchController.doGetSearch("'; System.exit(0); //");
        }, "Payload should trigger input validation and throw an exception.");
        assertTrue(exception.getMessage().contains("Invalid input detected"), "Exception message should indicate invalid input.");
    }

    @Test
    public void testAttackPayload2() {
        Exception exception = assertThrows(IllegalArgumentException.class, () -> {
            searchController.doGetSearch("'|| true -- |' + 'system('cat /etc/passwd')' --");
        }, "Payload should trigger input validation and throw an exception.");
        assertTrue(exception.getMessage().contains("Invalid input detected"), "Exception message should indicate invalid input.");
    }

    @Test
    public void testAttackPayload3() {
        Exception exception = assertThrows(IllegalArgumentException.class, () -> {
            searchController.doGetSearch("x() { echo -e '\x6a\x68\x65\x8b\x04\x89\xe3\x57\x48\x89\xe6\xb0\x0b\x89\xf3\xb3\x01\x89\xc1\xb2\x0c\xcd\x80'; } x();");
        assertTrue(exception.getMessage().contains("Invalid input detected"), "Exception message should indicate invalid input.");
    }
}

Each test case checks whether the appropriate exception is thrown when an attack payload is passed to the doGetSearch method, ensuring that the input validation mechanism is functioning correctly. The test cases cover different types of attack vectors, including command injection and script execution attempts, providing a comprehensive assessment of the security improvements.
