Horizon Alert
Summary of the vulnerability and why it matters
WWBN AVideo software contains a critical vulnerability that allows unauthenticated attackers to bypass login procedures and access any user account, including administrator accounts, by manipulating social login display names. This issue impacts systems that use Hybridauth for social logins, potentially exposing sensitive data and system control to unauthorized individuals. The main concern is confirming relevance and exposure within your deployed systems.
- Attackers bypass logins using social media names.
- Critical access gained without passwords.
- Confirm if this video platform is in use.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this vulnerability by leveraging the Hybridauth social login feature. By manipulating the display name associated with a social login, an attacker can trick the system into authenticating them as an existing user, including administrators, without needing a password. This bypasses the normal login process and grants unauthorized access.
- No prior authentication needed.
- Social login display name manipulation.
- Unauthorized user and administrator access.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow unauthenticated attackers to bypass login controls and impersonate any user, including administrators, when social login features are enabled. This could affect user accounts and administrative access to the video platform.
- User accounts and administrative access.
- Bypassed via crafted social login display names.
- Unauthorized access to platform features.
Operational Fix
Recommended remediation, mitigation, and detection steps
This critical authentication bypass vulnerability in WWBN AVideo impacts systems that utilize Hybridauth for social logins. The primary teams likely responsible for addressing this are the application owners who manage the AVideo deployment, and potentially infrastructure or platform teams if AVideo is part of a larger managed service. The immediate first step should be to identify all instances of AVideo, confirm their exposure and business criticality, and then coordinate with the vendor or internal teams to plan a remediation strategy based on the assessed risk.
- Application owners should lead remediation.
- Verify external reachability and asset criticality.
- Plan vendor coordination and patching.
