Official description
CWE-522 Insufficiently Protected Credentials vulnerability exists that could cause authentication bypass and unauthorized credential modification, potentially leading to compromise of managed devices, when a local privileged attacker leverages weaknesses in the handling and protection of stored credentials within the application.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
