Title
JATP Series: JATP Is susceptible to slow brute force attacks on the SSH service.
Summary
Due to insufficient server-side login attempt limit enforcement, a vulnerability in the SSH login service of Juniper Networks Juniper Advanced Threat Prevention (JATP) Series and Virtual JATP (vJATP) devices allows an unauthenticated, remote attacker to perform multiple login attempts in excess of the configured login attempt limit. Successful exploitation will allow the attacker to perform brute-force password attacks on the SSH service. This issue affects: Juniper Networks JATP and vJATP versions prior to 5.0.6.0.
Severity
5.3 (Medium)

CVE-2021-1311 (GCVE-0-2021-1311)

Vulnerability from cvelistv5 – Published: 2021-01-13 21:46 – Updated: 2024-11-12 20:39

Title
Cisco Webex Meetings and Cisco Webex Meetings Server Host Key Brute Forcing Vulnerability
Summary
A vulnerability in the reclaim host role feature of Cisco Webex Meetings and Cisco Webex Meetings Server could allow an authenticated, remote attacker to take over the host role during a meeting. This vulnerability is due to a lack of protection against brute forcing of the host key. An attacker could exploit this vulnerability by sending crafted requests to a vulnerable Cisco Webex Meetings or Webex Meetings Server site. A successful exploit would require the attacker to have access to join a Webex meeting, including applicable meeting join links and passwords. A successful exploit could allow the attacker to acquire or take over the host role for a meeting.

VLAI
Summary
Nextcloud server before 19.0.11, 20.0.10, 21.0.2 is vulnerable to brute force attacks due to lack of inclusion of IPv6 subnets in rate-limiting considerations. This could potentially result in an attacker bypassing rate-limit controls such as the Nextcloud brute-force protection.

Mitigation

Phase: Architecture and Design

Description:

  • 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 ID: MIT-4

Phase: Architecture and Design

Strategy: Libraries or Frameworks

Description:

  • 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.
