Horizon Alert
Summary of the vulnerability and why it matters
A critical vulnerability was discovered in the MISP threat intelligence platform that could allow unauthorized access and manipulation of sensitive data. This issue stems from a missing access control check in specific components of the application, which, if exploited, could have significant implications for data confidentiality and integrity. Understanding the relevance and exposure of this platform within your environment is the primary concern.
- Missing access check on core data features.
- Protects shared threat intelligence data.
- Confirm MISP relevance and exposure.
Attack Path
How an attacker could exploit the issue
An attacker could reach a vulnerable instance of MISP over the network and trigger a flaw in how the application checks user permissions. This could allow them to access or modify sensitive threat intelligence data.
- No authentication required to access.
- Accessing specific application features triggers the flaw.
- Leads to unauthorized data access and modification.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow unauthorized access to sensitive threat intelligence data and system configurations within MISP when it is exposed to a network. The absence of an access control check in specific controller and model files could potentially enable unauthenticated users to view or modify critical information.
- Sensitive threat intelligence data at risk.
- Unauthorized network access could expose data.
- Data theft or unauthorized modification possible.
Operational Fix
Recommended remediation, mitigation, and detection steps
The MISP platform, commonly deployed as an internet-facing threat intelligence application, is susceptible to this critical vulnerability. Ownership typically falls to the security team managing the MISP instance, with potential coordination required from application or infrastructure teams. The immediate first step is to confirm the presence and accessibility of MISP, identify the accountable owner, and then prioritize remediation based on the platform's criticality and exposure.
- Confirm MISP deployment and owner.
- Verify accessibility and business criticality.
- Plan remediation or temporary risk reduction.
