   6 |         return yaml.load(f, Loader=yaml.FullLoader)

🔄 Data Flow Analysis

1. Step 1: The 'load_pipeline' function reads the YAML file from the 'path' parameter [test_scan/sast_test_suite_v2/python/yaml_pipeline_loader.py:3]
2. Step 2: The 'yaml.load()' function is used to deserialize the YAML data without any input validation [test_scan/sast_test_suite_v2/python/yaml_pipeline_loader.py:6]

💡 Detailed Explanation

The code uses the unsafe 'yaml.load()' function to deserialize YAML data from an attacker-controlled file. This allows the attacker to execute arbitrary code on the system by crafting a malicious YAML payload.

⚠️ Proof of Concept Exploit

   7 |     cmd = make_backup_command(path)
   8 |     # final sink, critical
   9 |     subprocess.Popen(cmd, shell=True)

🔄 Data Flow Analysis

1. Step 1: The `path` parameter is retrieved from the user's request [test_scan/sast_test_suite_v2/python/web.py:7]
2. Step 2: The `path` parameter is used to construct the `cmd` variable, which is then passed to `subprocess.Popen()` with `shell=True` [test_scan/sast_test_suite_v2/python/web.py:9]

💡 Detailed Explanation

The `subprocess.Popen()` function is used with the `shell=True` parameter, which allows user-controlled input (`path`) to be directly executed as a shell command. An attacker could inject malicious commands into the `path` parameter and gain arbitrary code execution on the server.

⚠️ Proof of Concept Exploit

path = request.GET.get("path", "/tmp")
cmd = make_backup_command(path)
subprocess.Popen(cmd, shell=True)

💡 Detailed Explanation

This code contains a Command Injection - Runtime.exec concat vulnerability (CWE-78). The vulnerable code pattern 'Runtime.getRuntime().exec("git clone " + request.getParameter("repo"));' allows an attacker to potentially exploit this security weakness. This could lead to unauthorized access, data exposure, or system compromise depending on the context.

🔧 Suggested Fix

Use safe APIs that don't invoke shell commands, or properly sanitize all inputs

💡 Detailed Explanation

This code contains a Code Injection - exec with variable vulnerability (CWE-94). The vulnerable code pattern '// preload.js contains: contextBridge.exposeInMainWorld('run', cmd => require('child_process').exec(' allows an attacker to potentially exploit this security weakness. This could lead to unauthorized access, data exposure, or system compromise depending on the context.

🔄 Data Flow Analysis

1. Step 1: The `where_clause` parameter is passed to the `run_report` function [test_scan/sast_test_suite_v2/python/reporting.py:8]
2. Step 2: The `where_clause` is concatenated into the SQL query without any sanitization or validation [test_scan/sast_test_suite_v2/python/reporting.py:9]
3. Step 3: The malicious SQL query is executed on the database, potentially exposing sensitive data or allowing further attacks [test_scan/sast_test_suite_v2/python/reporting.py:10]

💡 Detailed Explanation

The `where_clause` parameter is directly concatenated into the SQL query, allowing an attacker to inject malicious SQL code. This could allow the attacker to retrieve sensitive data, modify or delete database records, or even execute arbitrary commands on the database server.

2. Step 2: The 'BUILD_SECRET' value is assigned to the 'INTERNAL_TOKEN' environment variable. [test_scan/sast_test_suite_v2/docker/Dockerfile:3]

💡 Detailed Explanation

The Dockerfile hardcodes the 'BUILD_SECRET' environment variable as the value for 'INTERNAL_TOKEN'. This means that the internal token or secret is stored in the Docker image, which could be exposed if the image is shared or accessed by an attacker. This could lead to unauthorized access or privilege escalation.

💡 Detailed Explanation

The code uses the ECB (Electronic Codebook) mode of AES encryption, which is a weak and insecure mode of operation. ECB mode does not provide any protection against data patterns, allowing attackers to potentially decrypt sensitive information if they gain access to the encrypted data.

⚠️ Proof of Concept Exploit

An attacker could potentially inject malicious SQL code into the '$q' variable, leading to unauthorized access to the database and potential data compromise.

⚠️ Proof of Concept Exploit

$q = "SELECT * FROM accounts WHERE id=${id}"; $db->query($q);

' OR '1'='1

✅ Exact Fix Code

$id = $_GET['id']; $q = $db->prepare("SELECT * FROM accounts WHERE id = ?"); $q->bind_param("i", $id); $q->execute();

📄 Code Context

   1 | public class UserService {
   2 |     @Autowired
   3 |     Database db;
   4 | 
   5 |     public void fetchUser(String rawId) {
   6 |         String q = "SELECT * FROM users WHERE id=" + rawId;
   7 |         db.run(q);
   8 |     }
   9 | }

🔄 Data Flow Analysis

1. Step 1: User provides input rawId [test_scan/sast_test_suite/UserService.java:4]
2. Step 2: rawId is concatenated into SQL query string [test_scan/sast_test_suite/UserService.java:6]
3. Step 3: Unsanitized SQL query is executed [test_scan/sast_test_suite/UserService.java:7]

💡 Detailed Explanation

The code is vulnerable to SQL injection because it passes the unsanitized SQL query string (q) directly to the `db.run()` method, which can execute the query. An attacker could potentially inject malicious SQL code into the query and gain unauthorized access to the database.

⚠️ Proof of Concept Exploit

db.run(q);

'; DROP TABLE users; --

✅ Exact Fix Code

String q = "SELECT * FROM users WHERE id = ?"; db.run(q, rawId);

📄 Code Context

   1 | crypto.pbkdf2Sync(pass, salt, 1000, 64, 'sha256');

🔄 Data Flow Analysis

1. Step 1: The `crypto.pbkdf2Sync()` function is called with the password, salt, 1,000 iterations, 64 bytes, and the 'sha256' algorithm. [test_scan/sast_test_suite/weak_pbkdf2.js:1]

💡 Detailed Explanation

The code uses PBKDF2 with only 1,000 iterations, which is considered a weak configuration and can make the password hash vulnerable to brute-force attacks. Attackers could potentially recover the original password by guessing and testing a large number of potential passwords against the hash.

⚠️ Proof of Concept Exploit

crypto.pbkdf2Sync(pass, salt, 1000, 64, 'sha256');

An attacker could perform a brute-force attack on the password hash to recover the original password.

✅ Exact Fix Code

crypto.pbkdf2Sync(pass, salt, 100000, 64, 'sha256');

📄 Code Context

   1 | { "oauth_client_secret": "12345-SECRET" }

🔄 Data Flow Analysis

1. Step 1: The OAuth client secret is hardcoded in the JSON file [test_scan/sast_test_suite/oauth.json:1]

💡 Detailed Explanation

The OAuth client secret is hardcoded in the JSON file, which means it could be easily accessed by an attacker. This could allow an attacker to impersonate the application and gain unauthorized access to sensitive data or resources.

⚠️ Proof of Concept Exploit

{ "oauth_client_secret": "12345-SECRET" }

Use the hardcoded client secret to authenticate as the application and access protected resources

✅ Exact Fix Code

{ "oauth_client_secret": "$OAUTH_CLIENT_SECRET" }

📄 Code Context

   1 | <div id="login"></div>
   2 | <script>
   3 |     let u = location.hash.slice(1);
   4 |     document.getElementById(u).innerHTML = "HI";
   5 | </script>

🔄 Data Flow Analysis

1. Step 1: The URL hash fragment is retrieved and stored in the 'u' variable. [test_scan/sast_test_suite/dom_clobber.html:3]
2. Step 2: The 'u' variable is used to select an element by its ID and set its 'innerHTML' property, allowing the attacker to inject arbitrary HTML. [test_scan/sast_test_suite/dom_clobber.html:4]

💡 Detailed Explanation

The code is vulnerable to DOM Clobbering, where an attacker can inject malicious HTML into the page via the URL hash fragment. This allows the attacker to overwrite existing DOM elements with their own, potentially executing arbitrary JavaScript and leading to a Cross-Site Scripting (XSS) vulnerability.

⚠️ Proof of Concept Exploit

document.getElementById(u).innerHTML = "HI";

http://example.com/test_scan/sast_test_suite/dom_clobber.html#login%3C%2Fdiv%3E%3Cscript%3Ealert(1)%3C%2Fscript%3E

✅ Exact Fix Code

let u = location.hash.slice(1);
const element = document.createElement('div');
element.textContent = 'HI';
document.getElementById('login').appendChild(element);

📄 Code Context

   1 | Cipher c = Cipher.getInstance("AES/ECB/NoPadding");

🔄 Data Flow Analysis

1. Step 1: The Cipher object is created using the 'AES/ECB/NoPadding' algorithm [test_scan/sast_test_suite/ecb_crypto.java:1]

💡 Detailed Explanation

The code uses AES encryption in ECB mode, which is known to be vulnerable to certain attacks as it does not provide sufficient randomization and predictable ciphertext patterns. This can lead to the exposure of sensitive data if the same plaintext is encrypted multiple times.

⚠️ Proof of Concept Exploit

Cipher c = Cipher.getInstance("AES/ECB/NoPadding");

Attacker can use known plaintext attacks to deduce the underlying encryption key and gain access to sensitive data

✅ Exact Fix Code

Cipher c = Cipher.getInstance("AES/GCM/NoPadding");

📄 Code Context

   1 | const deepmerge = require('deepmerge');
   2 | let obj = deepmerge({}, JSON.parse(req.body));

🔄 Data Flow Analysis

1. Step 1: The 'req.body' contains user-supplied JSON data [test_scan/sast_test_suite/prototype_pollution.js:2]
2. Step 2: The 'deepmerge' library is used to merge the user-supplied JSON data into an empty object [test_scan/sast_test_suite/prototype_pollution.js:2]

💡 Detailed Explanation

The code uses the 'deepmerge' library to merge user-supplied JSON data ('req.body') into an empty object. This can lead to Prototype Pollution, where an attacker can modify the prototype of Object, affecting all objects in the application and potentially leading to Remote Code Execution or other serious consequences.

⚠️ Proof of Concept Exploit

let obj = deepmerge({}, JSON.parse(req.body));

{"__proto__": {"isAdmin": true}}

✅ Exact Fix Code

let obj = {...JSON.parse(req.body)};

🔄 Data Flow Analysis

1. Step 1: The hardcoded API key 'sk-secret-key-12345' is defined in the code [test_scan/files (1)/test_vulnerable.py:47]

💡 Detailed Explanation

The API key 'sk-secret-key-12345' is hardcoded in the source code, allowing any attacker with access to the code to potentially use the API key for unauthorized access or abuse. This could lead to a compromise of the application's API and the data it protects.

⚠️ Proof of Concept Exploit

API_KEY = "sk-secret-key-12345"

Use the hardcoded API key to make unauthorized API calls

✅ Exact Fix Code

🔄 Data Flow Analysis

1. Step 1: The user input 'user_id' is retrieved from the request [test_scan/files (1)/test_vulnerable.py:17]
2. Step 2: The user input 'user_id' is directly included in the SQL query without any sanitization [test_scan/files (1)/test_vulnerable.py:18]
3. Step 3: The SQL query is executed, allowing the injected SQL code to be executed [test_scan/files (1)/test_vulnerable.py:19]

💡 Detailed Explanation

The user input 'user_id' is directly included in the SQL query without any sanitization, allowing an attacker to inject malicious SQL code. This could lead to a compromise of the database, including data leakage, unauthorized access, and even remote code execution.

⚠️ Proof of Concept Exploit

🔄 Data Flow Analysis

1. Step 1: The user input 'filename' is retrieved from the request [test_scan/files (1)/test_vulnerable.py:41]
2. Step 2: The user input 'filename' is directly included in the file path without any validation [test_scan/files (1)/test_vulnerable.py:42]
3. Step 3: The file is opened and read, potentially exposing sensitive information

💡 Detailed Explanation

The user input 'filename' is directly included in the file path without any validation, allowing an attacker to access files outside of the intended directory. This could lead to the disclosure of sensitive information, such as system files or other application data.

⚠️ Proof of Concept Exploit

🔄 Data Flow Analysis

1. Step 1: The IAM policy grants full permissions to any resource. [test_scan/vuln_samples/iam_policy.json:4]

💡 Detailed Explanation

The IAM policy grants the 'Allow' effect with the wildcard '*' action and resource, which allows the principal (user, role, or group) to perform any action on any AWS resource. This can lead to privilege escalation and unauthorized access to sensitive data or resources.

⚠️ Proof of Concept Exploit

"Statement": [ { "Effect": "Allow", "Action": "*", "Resource": "*" } ]

An attacker with this policy attached can perform any action on any AWS resource, including accessing sensitive data, modifying configurations, or launching malicious instances.
