CWE-257 Storing Passwords in a Recoverable Format

The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.

• Confidentiality, Access Control: Gain Privileges or Assume Identity — User's passwords may be revealed. • Access Control: Gain Privileges or Assume Identity — Revealed passwords may be reused elsewhere to impersonate the users in question.

• [Architecture and Design] Use strong, non-reversible encryption to protect stored passwords.

• Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

• CVE-2022-30018: A messaging platform serializes all elements of User/Group objects, making private information available to adversaries
