As of v1.5.0, the Argo API does not implement anti-automation measures such as rate limiting, account lockouts, or other anti-bruteforce measures. Attackers can submit an unlimited number of authentication attempts without consequence.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to versions 2.8.13, 2.9.9, and 2.10.4, an attacker can effectively bypass the rate limit and brute force protections by exploiting the application's weak cache-based mechanism. This loophole in security can be combined with other vulnerabilities to attack the default admin account. This flaw undermines a patch for CVE-2020-8827 intended to protect against brute-force attacks. The application's brute force protection relies on a cache mechanism that tracks login attempts for each user. This cache is limited to a `defaultMaxCacheSize` of 1000 entries. An attacker can overflow this cache by bombarding it with login attempts for different users, thereby pushing out the admin account's failed attempts and effectively resetting the rate limit for that account. This is a severe vulnerability that enables attackers to perform brute force attacks at an accelerated rate, especially targeting the default admin account. Users should upgrade to version 2.8.13, 2.9.9, or 2.10.4 to receive a patch.

The telnet server for 3Com hardware such as PS40 SuperStack II does not delay or disconnect remote attackers who provide an incorrect username or password, which makes it easier to break into the server via brute force password guessing.

BookWyrm is a social network for tracking reading. Versions prior to 0.4.5 were found to lack rate limiting on authentication views which allows brute-force attacks. This issue has been patched in version 0.4.5. Admins with existing instances will need to update their `nginx.conf` file that was created when the instance was set up. Users are advised advised to upgrade. Users unable to upgrade may update their nginx.conf files with the changes manually.

Zammad 5.2.0 is vulnerable to privilege escalation. Zammad has a prevention against brute-force attacks trying to guess login credentials. After a configurable amount of attempts, users are invalidated and logins prevented. An attacker might work around this prevention, enabling them to send more than the configured amount of requests before the user invalidation takes place.

LimitLoginAttempts.php in the limit-login-attempts-reloaded plugin before 2.17.4 for WordPress allows a bypass of (per IP address) rate limits because the X-Forwarded-For header can be forged. When the plugin is configured to accept an arbitrary header for the client source IP address, a malicious user is not limited to perform a brute force attack, because the client IP header accepts any arbitrary string. When randomizing the header input, the login count does not ever reach the maximum allowed retries.

User login brute force protection functionality bypass

In Sorcery before 0.15.0, there is a 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. This has been patched in 0.15.0.

Improper Restriction of Excessive Authentication Attempts in GitHub repository wger-project/wger prior to 2.2.
