GHSA-JC8M-CXHJ-668X
Vulnerability from github – Published: 2020-05-07 21:16 – Updated: 2023-05-16 16:16Impact
Brute force vulnerability when using password authentication via Sorcery. The brute force protection submodule will prevent a brute force attack for the defined lockout period, but once expired protection will not be re-enabled until a user or malicious actor logs in successfully. This does not affect users that do not use the built-in brute force protection submodule, nor users that use permanent account lockout.
Patches
Patched as of version 0.15.0.
Workarounds
Currently no workarounds, other than monkey patching the authenticate method provided by Sorcery or upgrading to version 0.15.0.

"summary": "Improper Restriction of Excessive Authentication Attempts in Sorcery"
}
Mitigation
- Common protection mechanisms include:
- Disconnecting the user after a small number of failed attempts
- Implementing a timeout
- Locking out a targeted account
- Requiring a computational task on the user's part.
Mitigation MIT-4
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
- Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
CAPEC-16: Dictionary-based Password Attack
An attacker tries each of the words in a dictionary as passwords to gain access to the system via some user's account. If the password chosen by the user was a word within the dictionary, this attack will be successful (in the absence of other mitigations). This is a specific instance of the password brute forcing attack pattern.
Dictionary Attacks differ from similar attacks such as Password Spraying (CAPEC-565) and Credential Stuffing (CAPEC-600), since they leverage unknown username/password combinations and don't care about inducing account lockouts.
CAPEC-49: Password Brute Forcing
An adversary tries every possible value for a password until they succeed. A brute force attack, if feasible computationally, will always be successful because it will essentially go through all possible passwords given the alphabet used (lower case letters, upper case letters, numbers, symbols, etc.) and the maximum length of the password.
CAPEC-560: Use of Known Domain Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate credentials (e.g. userID/password) to achieve authentication and to perform authorized actions under the guise of an authenticated user or service.
CAPEC-565: Password Spraying
In a Password Spraying attack, an adversary tries a small list (e.g. 3-5) of common or expected passwords, often matching the target's complexity policy, against a known list of user accounts to gain valid credentials. The adversary tries a particular password for each user account, before moving onto the next password in the list. This approach assists the adversary in remaining undetected by avoiding rapid or frequent account lockouts. The adversary may then reattempt the process with additional passwords, once enough time has passed to prevent inducing a lockout.
CAPEC-600: Credential Stuffing
An adversary tries known username/password combinations against different systems, applications, or services to gain additional authenticated access. Credential Stuffing attacks rely upon the fact that many users leverage the same username/password combination for multiple systems, applications, and services.
CAPEC-652: Use of Known Kerberos Credentials
An adversary obtains (i.e. steals or purchases) legitimate Kerberos credentials (e.g. Kerberos service account userID/password or Kerberos Tickets) with the goal of achieving authenticated access to additional systems, applications, or services within the domain.
CAPEC-653: Use of Known Operating System Credentials
An adversary guesses or obtains (i.e. steals or purchases) legitimate operating system credentials (e.g. userID/password) to achieve authentication and to perform authorized actions on the system, under the guise of an authenticated user or service. This applies to any Operating System.
