Missing Authentication in RansomLook Admin Panel

Publication date: 2026-08-24

Last updated on: 2026-08-24

Assigner: CIRCL

Description
RansomLook contains a missing authentication vulnerability in the /admin/crypto/group/new endpoint. While the endpoint provides an administrative function for creating new crypto group entries, it was not protected by the application's authentication mechanism. An unauthenticated remote attacker able to access the RansomLook web interface could therefore submit requests to this endpoint and create crypto group entries without possessing a valid authenticated session or administrative credentials. Successful exploitation allows an attacker to make unauthorized modifications to data that should only be manageable by authenticated administrators. Depending on how crypto group information is subsequently consumed by RansomLook, malicious or fraudulent entries could also affect the integrity of information presented or processed by the application. The vulnerability is addressed by applying the flask_login.login_required decorator to the /admin/crypto/group/new route, ensuring that only authenticated users can access the functionality.

Executive Summary

RansomLook has a missing authentication vulnerability in the /admin/crypto/group/new endpoint. This endpoint allows creating crypto group entries but was not protected by authentication. An unauthenticated attacker could access this endpoint and create unauthorized entries without valid credentials.

Detection Guidance

To detect this vulnerability, check if unauthenticated requests can access the /admin/crypto/group/new endpoint. Use tools like curl to send a GET or POST request to the endpoint and verify if it responds without requiring authentication. Example command: curl -v http://<target-ip>/admin/crypto/group/new

Impact Analysis

An attacker could exploit this to make unauthorized modifications to sensitive data that should only be manageable by administrators. This could lead to data integrity issues or fraudulent entries affecting the application's functionality.

Compliance Impact

This vulnerability could lead to unauthorized data modifications, potentially violating integrity requirements in GDPR and HIPAA. Unauthenticated access to administrative functions may result in non-compliance with access control and audit logging mandates.

Mitigation Strategies

Apply the flask_login.login_required decorator to the /admin/crypto/group/new route to enforce authentication. This ensures only authenticated users can access the endpoint. Refer to the commit fc25bc4 for implementation details.
