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

### Summary OliveTin’s live EventStream broadcasts execution events and action output to authenticated dashboard subscribers without enforcing per-action authorization. A low-privileged authenticated user can receive output from actions they are not allowed to view, resulting in broken access control and sensitive information disclosure. I validated this on OliveTin 3000.10.2. ### Details The issue is in the live event streaming path. EventStream() only checks whether the caller may access the dashboard, then registers the user as a stream subscriber: - service/internal/api/api.go:776 After subscription, execution events are broadcast to all connected clients without checking whether each recipient is authorized to view logs for the action: - service/internal/api/api.go:846 OnExecutionStarted - service/internal/api/api.go:869 OnExecutionFinished - service/internal/api/api.go:1047 OnOutputChunk The event payload includes action output through: - service/internal/api/api.go:295 internalLogEntryToPb - service/internal/api/api.go:302 Output By contrast, the normal log APIs do apply per-action authorization checks: - service/internal/api/api.go:518 GetLogs - service/internal/api/api.go:585 GetActionLogs - service/internal/api/api.go:544 isLogEntryAllowed Root cause: - the subscription path enforces only coarse dashboard access - execution callbacks broadcast to every connected client - no per-recipient ACL check is applied before sending action metadata or output I validated the issue using: - an admin user with full ACLs - an alice user with no ACLs - a protected action that outputs TOPSECRET=alpha-bravo-charlie Despite having no relevant ACLs, alice still receives the ExecutionFinished event for the privileged action, including the protected output. ### PoC Tested version: ``` - 3000.10.2 ``` 1. Fetch and check out 3000.10.2 in a clean worktree: ```bash git -C OliveTin fetch origin tag 3000.10.2 git -C OliveTin worktree add /home/kali/CVE/OliveTin-3000.10.2 3000.10.2 ``` 2. Copy the PoC test into the clean tree: ```bash cp OliveTin/service/internal/api/event_stream_leak_test.go \ OliveTin-3000.10.2/service/internal/api/ ``` 3. Run the targeted PoC test: ```bash cd OliveTin-3000.10.2/service go test ./internal/api -run TestEventStreamLeaksUnauthorizedExecutionOutput -count=1 -timeout 30s -v ``` 4.

A low-privileged authenticated user can subscribe to EventStream and receive: - action execution metadata - execution tracking IDs - initiating username - live output chunks - final command output Who is impacted: - multi-user OliveTin deployments - environments where privileged actions produce secrets, tokens, internal system details, or other sensitive operational output - deployments where lower-privileged authenticated users can access the dashboard and subscribe to live events This bypasses intended per-action log/view restrictions for protected actions.

Authentication bypass in Lantronix EDS3000PS device servers (firmware 3.1.0.0R2, EDS3016PS1NS and EDS3008PS1NS variants) lets a remote unauthenticated attacker reach protected management pages by appending a specific suffix to the request URL and supplying an Authorization header that uses 'admin' as the username. Successful bypass yields full administrative control of the serial-to-Ethernet device server without valid credentials. There is no public exploit identified at time of analysis and EPSS is very low (0.03%), but the flaw is trivially exploitable and carries a CVSS 4.0 base score of 9.3.
