CVE-2024-11717 (GCVE-0-2024-11717)
Vulnerability from cvelistv5
Published

CWE
  • CWE-837 - Improper Enforcement of a Single, Unique Action
  • CWE-1391 - Use of Weak Credentials
Summary
Tokens in CTFd used for account activation and password resetting can be used interchangeably for these operations. When used, they are sent to the server as a GET parameter and they are not single use, which means, that during token expiration time an on-path attacker might reuse such a token to change user's password and take over the account. Moreover, the tokens also include base64 encoded user email. This issue impacts releases up to 3.7.4 and was addressed by pull request 2679 https://github.com/CTFd/CTFd/pull/2679  included in 3.7.5 release.

CVE-2024-4629 (GCVE-0-2024-4629)
Vulnerability from cvelistv5
Published

CWE
  • CWE-837 - Improper Enforcement of a Single, Unique Action
Summary
A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.
