Title

Crabbox < 0.9.0 Authentication Bypass via Admin Claim Injection

Summary

Crabbox before 0.9.0 contains an authentication bypass vulnerability in the coordinator user-token verification path where the verifyUserToken() function fails to reject payloads containing an admin claim, allowing attackers to escalate privileges. An attacker with access to the shared non-admin token can craft a user-token payload with admin: true, sign it using HMAC-SHA256, and present it to admin-only coordinator routes to gain full coordinator admin access including lease visibility, pool state management, and forced release operations.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
