Command line arguments can be dangerous just like any other user input. They should never be used without being first validated and sanitized. Remember also that any user can retrieve the list of processes running on a system, which makes the arguments provided to them visible. Thus passing sensitive information via command line arguments should be considered as insecure. This rule raises an issue when on every program entry points (main methods) when command line arguments are used. The goal is to guide security code reviews. Sanitize all command line arguments before using them. For more information checkout the CWE-88 (https://cwe.mitre.org/data/definitions/88.html) advisory.

When software generates predictable values in a context requiring unpredictability, it may be possible for an attacker to guess the next value that will be generated, and use this guess to impersonate another user or access sensitive information. As the Math.random() function relies on a weak pseudorandom number generator, this function should not be used for security-critical applications or for protecting sensitive data. In such context, a cryptographically strong pseudorandom number generator (CSPRNG) should be used instead. For more information checkout the CWE-338 (https://cwe.mitre.org/data/definitions/338.html) advisory.

Arbitrary OS command injection vulnerabilities are more likely when a shell is spawned rather than a new process, indeed shell meta-chars can be used (when parameters are user-controlled for instance) to inject OS commands. For more information checkout the CWE-78 (https://cwe.mitre.org/data/definitions/78.html) advisory.

SQL queries often need to use a hardcoded SQL string with a dynamic parameter coming from a user request. Formatting a string to add those parameters to the request is a bad practice as it can result in an SQL injection. The safe way to add parameters to a SQL query is to use SQL binding mechanisms. For more information checkout the CWE-564 (https://cwe.mitre.org/data/definitions/564.html) and OWASP A1:2017 (https://owasp.org/www-project-top-ten/2017/A1_2017-Injection.html) advisory.

The debugger statement can be placed anywhere in procedures to suspend execution. Using the debugger statement is similar to setting a breakpoint in the code. By definition such statement must absolutely be removed from the source code to prevent any unexpected behavior or added vulnerability to attacks in production. For more information checkout the CWE-489 (https://cwe.mitre.org/data/definitions/489.html) advisory.

Windows registry modification detected

Session storage and local storage are HTML 5 features which allow developers to easily store megabytes of data client-side, as opposed to the 4Kb cookies can accommodate. While useful to speed applications up on the client side, it can be dangerous to store sensitive information this way because the data is not encrypted by default and any script on the page may access it. This rule raises an issue when the localStorage and sessionStorage API's are used. For more information checkout the OWSAP A3:2017 (https://owasp.org/www-project-top-ten/2017/A3_2017-Sensitive_Data_Exposure.html) advisory.

Browsers allow message exchanges between Window objects of different origins. Because any window can send / receive messages from other window it is important to verify the sender's / receiver's identity: When sending message with postMessage method, the identity's receiver should be defined (the wildcard keyword (*) should not be used).\nWhen receiving message with message event, the sender's identity should be verified using the origin and possibly source properties. For more information checkout the OWASP A2:2017 (https://owasp.org/www-project-top-ten/2017/A2_2017-Broken_Authentication) and (https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage) advisory.

Same origin policy in browsers prevents, by default and for security-reasons, a javascript frontend to perform a cross-origin HTTP request to a resource that has a different origin (domain, protocol, or port) from its own. The requested target can append additional HTTP headers in response, called CORS, that act like directives for the browser and change the access control policy / relax the same origin policy. The Access-Control-Allow-Origin header should be set only for a trusted origin and for specific resources. For more information checkout the OWASP A6:2017 (https://owasp.org/www-project-top-ten/2017/A6_2017-Security_Misconfiguration.html) advisory.
