Authentication Bypass

auth CRITICAL

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

How It Works

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications. Instead of cracking passwords through brute force, attackers manipulate the authentication process itself to gain unauthorized entry. This typically occurs through one of several pathways: exploiting hardcoded credentials embedded in source code or configuration files, manipulating parameters in authentication requests to skip verification steps, or leveraging broken session management that fails to properly validate user identity.

The attack flow often begins with reconnaissance to identify authentication endpoints and their underlying logic. Attackers may probe for default administrative credentials that were never changed, test whether certain URL paths bypass login requirements entirely, or intercept and modify authentication tokens to escalate privileges. In multi-step authentication processes, flaws in state management can allow attackers to complete only partial verification steps while still gaining full access.

More sophisticated variants exploit single sign-on (SSO) or OAuth implementations where misconfigurations in trust relationships allow attackers to forge authentication assertions. Parameter tampering—such as changing a "role=user" field to "role=admin" in a request—can trick poorly designed systems into granting elevated access without proper verification.

Impact

  • Complete account takeover — attackers gain full control of user accounts, including administrative accounts, without knowing legitimate credentials
  • Unauthorized data access — ability to view, modify, or exfiltrate sensitive information including customer data, financial records, and intellectual property
  • System-wide compromise — admin-level access enables installation of backdoors, modification of security controls, and complete infrastructure takeover
  • Lateral movement — bypassed authentication provides a foothold for moving deeper into networks and accessing additional systems
  • Compliance violations — unauthorized access triggers breach notification requirements and regulatory penalties

Real-World Examples

CrushFTP suffered a critical authentication bypass allowing attackers to access file-sharing functionality without any credentials. The vulnerability enabled direct server-side template injection, leading to remote code execution on affected systems. Attackers actively exploited this in the wild to establish persistent access to enterprise file servers.

Palo Alto's Expedition migration tool contained a flaw permitting attackers to reset administrative credentials without authentication. This allowed complete takeover of the migration environment, potentially exposing network configurations and security policies being transferred between systems.

SolarWinds Web Help Desk (CVE-2024-28987) shipped with hardcoded internal credentials that could not be changed through normal administrative functions. Attackers discovering these credentials gained full administrative access to helpdesk systems containing sensitive organizational information and user data.

Mitigation

  • Implement multi-factor authentication (MFA) — requires attackers to compromise additional verification factors beyond bypassed primary authentication
  • Eliminate hardcoded credentials — use secure credential management systems and rotate all default credentials during deployment
  • Enforce authentication on all endpoints — verify every request requires valid authentication; no "hidden" administrative paths should exist
  • Implement proper session management — use cryptographically secure session tokens, validate on server-side, enforce timeout policies
  • Apply principle of least privilege — limit damage by ensuring even authenticated users only access necessary resources
  • Regular security testing — conduct penetration testing specifically targeting authentication logic and flows

NetAlertX is a network, presence scanner, and alert framework. Prior to version 25.6.7, a vulnerability in the authentication logic allows users to bypass password verification using SHA-256 magic hashes, due to loose comparison in PHP. In vulnerable versions of the application, a password comparison is performed using the `==` operator at line 40 in front/index.php. This introduces a security issue where specially crafted "magic hash" values that evaluate to true in a loose comparison can bypass authentication. Because of the use of `==` instead of the strict `===`, different strings that begin with 0e and are followed by only digits can be interpreted as scientific notation (i.e., zero) and treated as equal. This issue falls under the Login Bypass vulnerability class. Users with certain "weird" passwords that produce magic hashes are particularly affected. Services relying on this logic are at risk of unauthorized access. Version 25.6.7 fixes the vulnerability.

Graylog is a free and open log management platform. In versions 6.2.0 to before 6.2.4 and 6.3.0-alpha.1 to before 6.3.0-rc.2, Graylog users can gain elevated privileges by creating and using API tokens for the local Administrator or any other user for whom the malicious user knows the ID. For the attack to succeed, the attacker needs a user account in Graylog. They can then proceed to issue hand-crafted requests to the Graylog REST API and exploit a weak permission check for token creation. This issue has been patched in versions 6.2.4 and 6.3.0-rc.2. A workaround involves disabling the respective configuration found in System > Configuration > Users > "Allow users to create personal access tokens".

A remote code execution vulnerability in GFI Kerio Control 9.4.5 allows attackers with administrative access to upload and execute arbitrary code through the firmware upgrade feature. The system upgrade mechanism accepts unsigned .img files, which can be modified to include malicious scripts within the upgrade.sh or disk image components. These modified upgrade images are not validated for authenticity or integrity, and are executed by the system post-upload, enabling root access.

A missing authentication vulnerability in the GFIAgent component of GFI Kerio Control 9.4.5 allows unauthenticated remote attackers to perform privileged operations. The GFIAgent service, responsible for integration with GFI AppManager, exposes HTTP services on ports 7995 and 7996 without proper authentication. The /proxy handler on port 7996 allows arbitrary forwarding to administrative endpoints when provided with an Appliance UUID, which itself can be retrieved from port 7995. This results in a complete authentication bypass, permitting access to sensitive administrative APIs.

An authentication bypass vulnerability exists in GFI Kerio Control 9.4.5 due to insecure default proxy configuration and weak access control in the GFIAgent service. The non-transparent proxy on TCP port 3128 can be used to forward unauthenticated requests to internal services such as GFIAgent, bypassing firewall restrictions and exposing internal management endpoints. This enables unauthenticated attackers to access the GFIAgent service on ports 7995 and 7996, retrieve the appliance UUID, and issue administrative requests via the proxy. Exploitation results in full administrative access to the Kerio Control appliance.

An information disclosure vulnerability exists in Ruijie NBR series routers (known to affect NBR2000G, NBR1300G, and NBR1000 models) via the /WEB_VMS/LEVEL15/ endpoint. By crafting a specific POST request with modified Cookie headers and specially formatted parameters, an unauthenticated attacker can retrieve administrative account credentials in plaintext. This flaw allows direct disclosure of sensitive user data due to improper authentication checks and insecure backend logic. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-05 UTC.

The Lead Form Data Collection to CRM plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on several functions in the ~/includes/LB_admin_ajax.php file in all versions up to, and including, 3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform several actions like updating settings. Initially this CVE was assigned specifically to all AJAX actions and the doFieldAjaxAction() function, however it was determined that CVE-2025-47690 is assigned to the doFieldAjaxAction() function that leads to arbitrary options updates.
