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

An issue was discovered on COROS PACE 3 devices through 3.0808.0. The BLE implementation of the COROS smartwatch does not support LE Secure Connections and instead enforces BLE Legacy Pairing. In BLE Legacy Pairing, the Short-Term Key (STK) can be easily guessed. This requires knowledge of the Temporary Key (TK), which, in the case of the COROS Pace 3, is set to 0 due to the Just Works pairing method. An attacker within Bluetooth range can therefore perform sniffing attacks, allowing eavesdropping on the communication.

An issue was discovered in the COROS application through 3.8.12 for Android. Bluetooth pairing and bonding is neither initiated nor enforced by the application itself. Also, the watch does not enforce pairing and bonding. As a result, any data transmitted via BLE remains unencrypted, allowing attackers within Bluetooth range to eavesdrop on the communication. Furthermore, even if a user manually initiates pairing and bonding in the Android settings, the application continues to transmit data without requiring the watch to be bonded. This fallback behavior enables attackers to exploit the communication, for example, by conducting an active machine-in-the-middle attack.

The GiveWP - Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to unauthorized view and modification of data due to an insufficient capability check on the permissionsCheck functions in all versions up to, and including, 4.3.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to view or delete fundraising campaigns, view donors' data, modify campaign events, etc.

The Versa Director SD-WAN orchestration platform implements Two-Factor Authentication (2FA) using One-Time Passcodes (OTP) delivered via email or SMS. Versa Director accepts untrusted user input when dispatching 2FA codes, allowing an attacker who knows a valid username and password to redirect the OTP delivery (SMS/email) to their own device. OTP/TOTP codes are not invalidated after use, enabling reuse by an attacker who has previously intercepted or obtained a valid code. In addition, the 2FA system does not adequately restrict the number or frequency of login attempts. The OTP values are generated from a relatively small keyspace, making brute-force attacks more feasible. Exploitation Status: Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers. Workarounds or Mitigation: Versa recommends that Director be upgraded to one of the remediated software versions.

Remote code execution vulnerability in Backup Server that allows authenticated domain users to execute arbitrary code with high severity (CVSS 8.8). The vulnerability requires valid domain credentials but no user interaction, making it a significant risk for organizations with Backup Server deployments in Active Directory environments. If actively exploited or with public POC availability, this represents an immediate priority for patching.

CryptPad versions prior to 2025.3.0 contain a critical authentication bypass vulnerability that allows attackers to circumvent Two-Factor Authentication (2FA) enforcement through a trivial path parameter manipulation. An attacker who obtains valid user credentials can bypass 2FA protection by URL-encoding a single character in the access path, gaining full account access without the second authentication factor. The vulnerability has a CVSS score of 9.1 (Critical) and requires no special privileges or user interaction to exploit.

CloudClassroom-PHP-Project v1.0 contains a critical SQL injection vulnerability in the loginlinkadmin.php component that allows unauthenticated attackers to bypass authentication and gain unauthorized administrative access by injecting malicious SQL payloads into the username field. With a CVSS score of 9.8 and network-accessible attack vector requiring no privileges or user interaction, this vulnerability poses immediate and severe risk to all deployments. While specific KEV status and EPSS data were not provided in the intelligence sources, the combination of complete authentication bypass capability, high CVSS score, and trivial exploitation complexity suggests this is actively exploitable and likely to be targeted by opportunistic attackers.
