Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability exists in MISP Modules that could allow an attacker to trick an authenticated user into performing unintended actions. This could lead to the modification of sensitive session data, which is a serious concern for the integrity of your threat intelligence platform.
- Requires authenticated user access.
- Affects session data integrity.
- Impacts threat intelligence operations.
Attack Path
How an attacker could exploit the issue
An attacker could exploit this CSRF vulnerability by tricking an authenticated user into visiting a malicious link or interacting with a crafted element. This would force the user's browser to send an unintended request to the MISP Modules home endpoint, potentially modifying session query data and allowing the attacker to gain unauthorized access or manipulate the system.
- Requires authenticated user.
- Targets MISP Modules home endpoint.
- User must be tricked.
Live Threat
Current exploitation, exposure, and threat context
This CSRF vulnerability in MISP Modules affects authenticated users by allowing unintended requests to the home endpoint, potentially modifying session query data. While attackers generally prefer vulnerabilities that grant broad unauthorized access or remote code execution, a CSRF that can alter critical configuration or query data within an authenticated session could still be valuable for targeted attacks or further exploitation if the MISP instance itself holds sensitive information. The fact that this requires authenticated access and user interaction, however, limits its appeal for widespread, opportunistic exploitation.
- Primarily targets authenticated users.
- Requires user interaction.
- No known public exploit.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize monitoring logs for unauthorized session modifications and unusual activity targeting the MISP Modules home endpoint. If exploitable, consider isolating the MISP Modules service from the network until a patch can be applied.
- Check logs for session data manipulation.
- Update MISP modules to the latest version.
- Restrict access to MISP modules.
