Horizon Alert
Summary of the vulnerability and why it matters
An authentication bypass vulnerability has been identified in Open XDMoD through version 7.5.0. This issue stems from a weak password reset mechanism, potentially allowing unauthorized account access through brute-force attacks. The technology affected is Open XDMoD, a system used for monitoring and analyzing high-performance computing usage.
- Weak password reset allows account takeover.
- Affects systems managing high-performance computing.
- Confirm relevance and review exposure.
Attack Path
How an attacker could exploit the issue
An attacker can bypass authentication by exploiting a weak password reset mechanism in Open XDMoD. By knowing that a password reset has been initiated, an attacker can perform a brute-force attack on the reset token, which is an MD5 hash. This allows them to take over user accounts.
- Attacker needs network access.
- Triggered by password reset process.
- Leads to account takeover.
Live Threat
Current exploitation, exposure, and threat context
A weak password reset mechanism could allow an attacker to bypass authentication and take over user accounts. This is possible when an attacker knows a victim has recently initiated a password reset and can perform a brute-force attack against a specific value.
- User account data could be compromised.
- Accounts may be taken over via brute-force.
- Unauthorized access to user services.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability affects Open XDMoD, a web-based analytics tool. The primary responsibility for addressing this issue likely lies with the platform or application owners who manage the Open XDMoD deployment. The first practical step is to identify all instances of Open XDMoD within the environment, confirm their exposure to the internet or internal networks, and ascertain their criticality to business operations to prioritize remediation efforts.
- Platform/application owners should address.
- Verify Open XDMoD instances and exposure.
- Plan risk-based remediation actions.
