Code obfuscation techniques 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.

Cryptographic operations detected

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.

System command execution detected

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.
