Improper Restriction of Excessive Authentication Attempts

OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 0.1.0 through 2.3.1, attackers could bypass the automatic user lockout mechanisms in the OpenBao Userpass or LDAP auth systems. This was caused by different aliasing between pre-flight and full login request user entity alias attributions. This is fixed in version 2.3.2. To work around this issue, existing users may apply rate-limiting quotas on the authentication endpoints:, see https://openbao.org/api-docs/system/rate-limit-quotas/.Show less

A vulnerability was found in macrozheng mall 1.0.3. It has been rated as problematic. Affected by this issue is some unknown functionality of the component Admin Login. The manipulation leads to improper restriction of excessive authentication attempts. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The vendor was contacted early about this disclosure but did not respond in any way.Show less

The affected product does not limit the number of attempts for inputting the correct PIN for a registered product, which may allow an attacker to gain unauthorized access using brute-force methods if they possess a valid device serial number. The API provides clear feedback when the correct PIN is entered. This vulnerability was patched in a server-side update on April 6, 2025.Show less

Trilium Notes is an open-source, cross-platform hierarchical note taking application with focus on building large personal knowledge bases. In versions below 0.97.0, a brute-force protection bypass in the initial sync seed retrieval endpoint allows unauthenticated attackers to guess the login password without triggering rate limiting. Trilium is a single-user app without a username requirement, and brute-force protection bypass makes exploitation much more feasible. Multiple features provided by Trilium (e.g. MFA, share notes, custom request handler) indicate that Trilium can be exposed to the internet. This is fixed in version 0.97.0.Show less

Vault and Vault Enterprise’s (“Vault”) user lockout feature could be bypassed for Userpass and LDAP authentication methods. Fixed in Vault Community Edition 1.20.1 and Vault Enterprise 1.20.1, 1.19.7, 1.18.12, and 1.16.23.Show less

A vulnerability has been identified in the Linux kernel's ksmbd component (kernel SMB/CIFS server). A security control designed to prevent dictionary attacks, which introduces a 5-second delay during session setup, can be bypassed through the use of asynchronous requests. This bypass negates the intended anti-brute-force protection, potentially allowing attackers to conduct dictionary attacks more efficiently against user credentials or other authentication mechanisms.Show less

Grandstream Networks UCM6510 v1.0.20.52 and before is vulnerable to Improper Restriction of Excessive Authentication Attempts. An attacker can perform an arbitrary number of authentication attempts using different passwords and eventually gain access to the targeted account using a brute force attack.Show less

A vulnerability was found in Mercusys MW301R 1.0.2 Build 190726 Rel.59423n. It has been rated as problematic. This issue affects some unknown processing of the component Login. The manipulation leads to improper restriction of excessive authentication attempts. The attack can only be initiated within the local network. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

In Eclipse GlassFish versions before 8.0.3 it is possible to perform Login Brute Force attacks as there is no limitation in the number of failed login attempts. GlassFish 8.0.3 adds automatic attack protection documented in https://glassfish.org/docs/latest/security-guide.html#brute-force-attack-protection .Show less

File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.34.1, a missing password policy and brute-force protection makes the authentication process insecure. Attackers could mount a brute-force attack to retrieve the passwords of all accounts in a given instance. This issue has been patched in version 2.34.1.Show less

Improper Restriction of Excessive Authentication Attempts vulnerability in Art-in Bilişim Teknolojileri ve Yazılım Hizm. Tic. Ltd. Şti. Wi-Fi Cloud Hotspot allows Authentication Abuse, Authentication Bypass. This issue affects Wi-Fi Cloud Hotspot: before 30.05.2025.Show less

A vulnerability, which was classified as critical, has been found in xxyopen/201206030 novel-plus up to 5.1.3. Affected by this issue is the function ajaxLogin of the file novel-admin/src/main/java/com/java2nb/system/controller/LoginController.java of the component CATCHA Handler. The manipulation leads to authentication bypass by capture-replay. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less
