CWE-522: Insufficiently Protected Credentials

What is CWE-522?

CWE-522 is Insufficiently Protected Credentials. The flaw arises when the product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval. The database currently holds 206 vulnerabilities mapped to CWE-522 and none of them are in the CISA Known Exploited Vulnerabilities catalog.

Official definition

ByMitre CWE

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

Characteristics

Modes of introduction

  • Architecture and Design: COMMISSION: This weakness refers to an incorrect design related to an architectural security tactic.
  • Implementation

Common consequences

ImpactScopeExplanation
Gain Privileges or Assume IdentityAccess ControlAn attacker could gain access to user accounts and access sensitive data used by the user accounts.

Risk mitigations

  1. Architecture and DesignUse an appropriate security mechanism to protect the credentials.
  2. Architecture and DesignMake appropriate use of cryptography to protect the credentials.
  3. ImplementationUse industry standards to protect the credentials (e.g. LDAP, keystore, etc.).

Detection methods

MethodApproachEffectiveness
Automated Static AnalysisAutomated 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.)High
