Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability involves a security misconfiguration in the MISP threat intelligence platform where password change requirements were not enabled by default. This could allow unauthorized access to sensitive threat intelligence data if an attacker can compromise a user's account. The main concern is confirming relevance and exposure.
- Weak password controls pose a data access risk.
- MISP platforms handle sensitive threat intelligence.
- Confirm if MISP is in use and its exposure.
Attack Path
How an attacker could exploit the issue
An attacker could target users of the MISP threat intelligence platform by exploiting a vulnerability in its password change functionality. This flaw allows an unauthenticated attacker to potentially reset any user's password without knowing the current one, leading to account takeover and unauthorized access to sensitive threat intelligence data.
- Unauthenticated access to the platform is required.
- A password change request triggers the vulnerability.
- Account takeover and data theft are possible.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability could allow an unauthenticated attacker to change any user's password without prior authentication, potentially leading to unauthorized access to sensitive threat intelligence data. This is possible when the `require_password_confirmation` setting is not enabled, which was the default in the affected version.
- User account credentials could be at risk.
- Attackers could change passwords without prior authentication.
- Unauthorized access to sensitive data may occur.
Operational Fix
Recommended remediation, mitigation, and detection steps
Security and infrastructure teams are likely responsible for addressing this vulnerability in MISP, as it's a web-based threat intelligence platform often exposed externally. The immediate first step is to locate all instances of the affected technology, confirm its accessibility and business criticality, identify the accountable owner, and then prioritize remediation based on the potential risk.
- Platform/Application owners should prioritize addressing this.
- Verify if password change functionality is used.
- Plan configuration update or vendor coordination.
